1. (1) Mountainous areas and plains - According to the values and sparseness of the contour lines, the southeast part of the map should be a mountainous area, and the northwest part of the map should be a plain, with an elevation of less than 200 meters above sea level, which is based on the natural area of the criteria for the division.
(2) Forestry and Farming Areas--According to the criteria for the division of agricultural areas, the mountainous areas in the southeast of the figure should be developed for forestry, and the plains in the northwest should become a farming area and be developed for cultivation. What should be done to develop the areas in the map that are steeper in slope and higher in elevation and where no trees grow? Although the entrance increases, the settlement expands, and the division into farming areas can increase food production. However, the slopes of the area are not suitable for farming and can cause soil erosion, affecting the environment of the whole region. Therefore, forestry should be developed.

1. There is similarity.
The dominant factor in the determination of boundary A is the influence of the summer winds, which roughly coincides with the 400 mm isoprecipitation line - the Northwest region is deep inland and hardly affected by the summer winds, and receives less precipitation and is drier. The eastern monsoon region is more affected by summer winds, has more precipitation, and is a humid and semi-humid region.
2. ①Boundary B is roughly closest to the distribution of the 0°C isotherm in January.
2. Boundary B is roughly closest to the distribution of the 800 mm isothermal precipitation line.
③The dominant factors in determining B are temperature and precipitation - a combination of climatic aspects.
④ Qinling-Huai River.
3. The boundaries of the first and the second ladders are basically coincident.
The dominant factor in the determination of boundary C is the topographical factor.
Section II Northern and Southern Regions 1. See the following table Qinling-Huai River North Qinling-Huai River South Qinling-Huai River Mean temperature in January (higher than 0 ℃/lower than 0 ℃) Lower than 0 ℃ Higher than 0 ℃ Annual precipitation Less than, less than 800 mm More than, more than 800 mm Main terrain Plateau, plains Plateau, plains, Hills, basins 2, the northern vegetation type is temperate deciduous broad-leaved forests, the southern vegetation type is subtropical evergreen broad-leaved forests, the main reason for the formation of the difference is the difference in temperature, the northern average temperature in January is lower than 0 ℃, the southern average temperature in January is higher than 0 ℃. Northern river flow is small, the southern river flow is large, the main reason for the formation of the difference is the difference in precipitation, the northern precipitation is less, the rainy season is short, the southern precipitation is more, the rainy season is long. Therefore, the dominant factor in the formation of natural differences between the southern and northern regions is climate, and there are obvious differences in temperature and precipitation.P10 Activity Question Answers Northern regions Southern regions Reasons Farming system Land-use type Dryland-dominated Paddy-field-dominated Climate Main crops Wheat, soybeans Rice, oilseed rape Climate Crop ripening One year or two years of ripening Three years of ripening Two years of ripening or three years of ripening Climate Traditional mode of transportation Land transportation is dominant Traditional transportation is dominated by land transportation, mostly using cars and horse-drawn carriages Water transportation Terrain Traditional dwellings Smaller roof slopes and thicker walls Larger roof slopes and higher walls Climate Other differences Clappers, Qinqiang, with high-pitched voices Yueju Opera, Huangmei Opera, with euphemistic voices 2. "Oranges are oranges when they are born in the south of the Huai River, and they are Hovenia when they are born in the north of the Huai River", which reflects the regional nature of agricultural production. is the difference in climate between the north and south of the Huai River, due to the differences in the natural conditions of the Huainan and Huabei (mainly climate), resulting in difficult to produce regional differences, so that the same seeds in the Huainan and Huabei bear fruit with different tastes. 3, the average temperature in January in the north is lower than 0 ℃, the winter temperatures are low, and lasts for a long time, and the temperature is too low for students to attend classes, so the northern winter holiday is longer, and the south is high temperature in the summer and rainy , and lasts for a long time, the temperature is too high, easy to heat stroke and other phenomena, students can not attend classes normally, so the southern summer vacation is longer. Northwest China and Qinghai-Tibet are deep inland and far away from the sea, plus the blockage of humid air currents by tall mountains, it is difficult for the humid air currents from the sea to reach, so precipitation is scarce and the climate is arid here. From east to west, the order is: grassland-desert grassland-desert P14 Activity Question Answers (1), The average annual temperature in Lhasa is around 7℃, and that in Chengdu is around 16℃. Lhasa is located at an average altitude of 4000 meters above the Tibetan Plateau, while Chengdu is located in the Sichuan Basin, the effect of terrain on the temperature is manifested in the temperature with the increase in altitude and decrease, roughly every 100 meters above sea level, the temperature drops 0.6 ℃, therefore, the same latitude zone, the higher the terrain, the lower the temperature. 2 rich solar energy: Tibetan Plateau terrain is high, the atmosphere is clean, thin, air transparency is good, solar Light through the atmosphere with less energy loss, more heat reaching the ground, coupled with the Tibetan Plateau sunny days, long hours of sunshine, so the Tibetan Plateau region has an abundance of solar energy. The birthplace of great rivers: the high terrain of the Qinghai-Tibetan region, so the climate is cold, many mountain ranges year-round snow, glaciers are widely spread, is the birthplace of many great rivers. p16 activity question answer: (1) Inner Mongolia is a temperate grassland pasture, pasture area, pasture grows high and lush; Qinghai-Tibetan region is an alpine steppe pasture, Qinghai-Tibetan region is high, mountain ranges, the pasture area is relatively small, the pasture grows short and sparse. The grassland area is relatively narrow, and the pasture grows short and sparse. The reasons for this difference are: A, different terrain, Inner Mongolia Plateau terrain is flat, undulating and gentle; Qinghai-Tibet region has many mountain ranges, rugged terrain; B, different climates. Inner Mongolia Plateau is a temperate continental climate, high summer temperatures, lush pastures, a wide variety of vegetation; Qinghai-Tibetan region belongs to the alpine climate, the average summer temperature is low, only suitable for cold-hardy grass and other plant growth. 2, Inner Mongolia pastoral area is one of China's famous four major pastoral areas, the residents of the pastoral area to the main grazing in the natural conditions of the area, the pasture grass grows vigorously, the residents of the area to these areas of grazing. In order to adapt to the nomadic life needs, herders generally live in the wool felt made of easy to dismantle, handling and installation of the yurt. A yurt is a round tent made of wooden poles and covered with white wool felt. The yurt has a door, a window and a roof that can be opened for light and ventilation. National Political and Cultural Center--Beijing 1. (1) Beijing is located roughly at 40°N, 116°E, on the northern edge of the North China Plain, facing the Bohai Sea in the southeast, and neighboring Hebei and Tianjin. The terrain is dominated by the plains, and the rivers flow roughly from the northwest to the southeast, so the terrain is high in the northwest and low in the southeast. (2), Beijing's geographic location, west of the Loess Plateau energy base and the vast northwest, southeast of the Bohai Sea reaching the plains, south of the productive Huanghuaihai Plain, to the northwest can enter the Inner Mongolia Plateau, to the east can enter the northeast. Energy, raw materials and food supplies were abundant. So the capital of new China was set in Beijing after the establishment of new China. 2, Beijing is the cultural center of China: a concentration of institutions of higher learning, numerous stadiums, museums, literary and artistic groups. p23 activity questions: 1, (1) after the liao dynasty, the site of the city of Beijing has undergone some spatial changes, broadly speaking: firstly, the spatial scope of the old city of Beijing is constantly expanding, and secondly, the spatial distribution of the city from the original Liao nanjing city gradually expanding to the north and east, and then shrinking southward during the Ming and Qing Dynasties. Ming and Qing dynasties and to the south, so that the outline of the old city from the square of the Liao Dynasty to the rectangular Jin, Yuan, to the Ming and Qing dynasties evolved into a "convex" shape. (2) The continuous change of the site of the old city of Beijing is closely related to the water source. From the figure, we can see that no matter how the city site changes, it is always necessary to ensure that there is an abundant water source near the city to provide the city with sufficient water for production and living. Therefore, as the city population continues to increase and the functions of the city continue to be enriched, the abundance of water is a direct constraint on the development of the city and the change of the city site.2. Reasonable practices for the protection of the Forbidden City are: (1) limiting the number of tickets sold per day; (2) promoting civilized and environmentally friendly behavior; (3) using modern information technology to carry out virtual tours; (4) increasing the efforts of the management; and (5) increasing the financial investment in the protection of the The Forbidden City. P26 Activity Question 1. The modernization of the city involves many aspects, which can be understood from the following aspects: the construction of transportation facilities; the amount of information; green space and environmental protection; housing; modern education technology; standard of living; clothing; abundant tourist resources; shopping convenience, etc. 2. (1) Justification is enough. (2) While building and developing the city, attention is paid to maintaining the pattern and original style of the old city, protecting and repairing important ancient buildings, gardens and characteristic neighborhoods, and expanding the construction of urban green spaces and urban water networks. In order to protect the environment, emphasis is placed on the development of enterprises and high-tech industries that consume less energy, less water and less pollution. Hong Kong and Macao 1. Hong Kong: 6070, Macao: 172442. Hong Kong is crowded and narrow, with a lot of mountainous areas and little flat land. The built-up areas are mainly located in mountainous areas with sparse vegetation, which fully protects the existing land resources.3. Going up to the sky: Avoiding the repeated wastage of land, making full use of the space, and maximizing the use of land resources. Going down to the sea: expanding the land area, disadvantage: destroying the ecological environment. 4. The construction of the urban environment is also very important. P32 Activity Question Talent flow: facilitating the exchange of talents between Hong Kong and Macao and the motherland mainland; scientific and technological exchanges: promoting the rapid development of science and technology in the two places; the tourism industry of Hong Kong and Macao is well developed and the number of Hong Kong and Macao travelers in the motherland's inner regions is on the increase, which pulls up the development of the economy of the Hong Kong and Macao regions. Xinjiang 1 Xinjiang's topography is characterized by "three mountains and two basins" ' "three mountains" refers to the north for the Altai Mountains, in the Tianshan Mountains, south for the Kunlun Mountains." The "two basins" refer to the Junggar Basin in the north and the Tarim Basin in the south. 2. (1) The population, cities and transportation facilities of the Tarim Basin are mainly located in the oases. Since Xinjiang is far from the sea, it is dry and has little rain, so its water sources are mainly alpine ice, snow and glacier meltwater. As a result of this water, many oases have appeared in the foothills at the edge of the basin, and the population and cities are concentrated in these oases. Cities and populations are also found along the rivers. The distribution of transportation facilities is inextricably linked with the population and cities, mostly along the edge of the basin, linking the population, cities and oases where economic activities are concentrated, which is close to the water source and also promotes the development of cities and the economy, and facilitates the people's life. (2) The oases are far away from each other, resulting in inconvenient local transportation and the lack of information communication between the people in the oases, which hinders the trade between the people in the oases and hinders the development of the local society and economy. The main way to improve the situation is to improve the local transportation conditions and build railroads or highways. (3) Desertification is most likely to occur in the fringe areas of oases, i.e. areas bordering on deserts. The environment in these areas is very fragile, and the destruction of vegetation and the irrational use of water resources can easily lead to desertification and salinization of land. When producing and living in these areas, people should protect the environment, prohibit overgrazing, prohibit the destruction of vegetation, rationally utilize water resources, and protect existing farmland. Activity 1: Xinjiang is located in the inland northwest of China, with little precipitation, strong sunshine, strong evaporation, scarce water resources, and extensive deserts. The construction of "qan'erjing" and other water conservancy projects adapted to the local environment to make up for the lack of local water resources, to maintain the survival of the oasis, the development of oasis agriculture with rich characteristics. Qan'erjing" consists of four parts: vertical wells, culverts, open channels and flood dams. The precious underground water is transported from the foothills to the basin through the culverts, irrigating many oases. Qan'erjing, together with the Great Wall of China and the Beijing-Hangzhou Grand Canal, is known as China's three major ancient projects.2 Positively, Xinjiang should do the following in the development and utilization of water resources: (1) more Qan'erjing irrigation projects should be maintained and constructed; (2) water conservancy infrastructure should be vigorously constructed, such as cross-boreal transfer of water and the construction of reservoirs, etc.; (3) advanced water-saving irrigation technologies, such as drip and sprinkler irrigation, should be actively adopted to develop water-saving agriculture (4) people should (4) People should conserve water and prevent water pollution; (5) change the structure of agricultural cultivation and increase the proportion of crops that use less water and are drought-resistant. 3. (1) Farmers in Turpan have adjusted the types of crops they grow in order to rapidly increase their income and get rich as soon as possible. The direction of adjustment is to grow specialty crops that meet market demand. (2) Some of the advanced technologies implemented in the region are in response to the scarcity of water resources in Xinjiang. With the lack of water resources and the limited area of oasis in Xinjiang, the adoption of advanced technology has not only rationally utilized soil and water resources, but also improved the yield and quality of agricultural products. (3) Suggestions: A, on TV, the Internet and other advertising, increase product promotion, B, local processing of fruits, fruit processing into industrial products, not only increased such as the local economy, but also to facilitate the long-distance transportation of products C, and actively adjust the industrial structure, the development of a variety of business as soon as possible out of poverty to become rich. Textbook P46 Activity 1 West-East Gas Pipeline on the significance of the economic development of the East and West is: the implementation of the West-East Gas Pipeline project, will enable China's central and western energy, raw material advantages to give full play to the rapid increase in local financial income, drive the local related industries, such as construction, steel industry development, to provide more employment opportunities for the local people, and greatly promote the economic development of the west, narrowing the economic gap between the East and the West. Meanwhile, the West-to-East Gas Pipeline Project At the same time, the implementation of the West-East Natural Gas Pipeline Project has alleviated the problem of energy shortage in the economically developed regions in the east, lowered production costs in the east, and improved the increasingly serious environmental situation in the east. 2. Xinjiang's oil and gas resources are very rich, with huge potential. The predicted reserves account for about 1/3 of the national total reserves, and the natural gas in the Tarewood Basin alone accounts for 22% of the total onshore natural gas resources in the country, and the West-East Natural Gas Pipeline Project will drive the development of large-scale oil and gas fields in the west such as Karamay, Luntai, and Kuqa, as well as the development of oil and gas fields in the Tsaidam Basin of Qinghai and the Yumen Basin of Gansu Province, etc. The West-East Natural Gas Pipeline Project will bring about economic benefits in the west in terms of: increasing the local financial income, driving the development of local related industries, and providing benefits to the local people. The economic benefits of the West-East Gas Pipeline Project to the west include: increasing local financial revenue, driving the development of local related industries, providing more employment opportunities for local people, greatly promoting the economic development of the western region, and narrowing the economic gap between the east and the west. During the construction process, the project must not exceed the prescribed limits to avoid damaging the surface vegetation. The implementation of the West-East Natural Gas Transmission Project has improved the energy structure of the cities and villages around the Tarim Basin and protected the local environment. Favourable factors for opening up the Pearl River Delta to the outside world: Location: The Pearl River Delta has an advantageous geographic location, being at the "southern gate" of the motherland, with the South China Sea in the south, adjacent to Hong Kong and Macao, and across the sea from Southeast Asia, with convenient land and sea transportation. Human factors: large population, abundant labor resources, many places are famous overseas Chinese hometowns, attracting a large number of overseas Chinese and overseas Chinese to invest here. Policy factors: the state has implemented the policy of "opening up to the outside world and prioritizing development" for the Pearl River Delta region. p531: (1) The per capita Gross Domestic Product (GDP) of the Pearl River Delta has grown rapidly, while that of the whole country has grown slowly, and the difference is very obvious. (2) This difference became more and more obvious after the mid-1980s. The reason for this phenomenon is that the Pearl River Delta has utilized its superior geographical location and a large number of overseas Chinese and overseas Chinese have come here to invest. The State has implemented an open-door policy in the Pearl River Delta and established special economic zones, focusing on the development of an externally oriented economy, which has greatly contributed to the rapid development of the economy of the Pearl River Delta. 2. The main factors affecting the industrial layout are: ① raw materials and fuel; ② land and labor; ③ market; ④ transportation conditions; ⑤ level of science and technology. The main reason why the Yangtze River Delta has become a hotspot for Taiwanese investment is that it is rich in human resources and strong in science and technology, which makes it more suitable for the development of high-tech industries and promotes the rapid development of the economy. 3. As shown in the table below. Textbook P56 Activity
1 In 1984, at the beginning of the reform and opening-up period, the distribution of cities and towns in the Pearl River Delta region was sparse, the number of cities and towns was relatively small, the scale of cities and towns was relatively small, and the growth of the non-agricultural population was slow. The main reason for this is that with its advantageous geographical location, famous overseas Chinese hometowns and preferential policies from the State, the Pearl River Delta has experienced rapid development of export-oriented industries, which require a large number of laborers. The population has been moving southward to the Pearl River Delta in search of better employment opportunities, higher economic incomes and a better standard of living, resulting in a sharp increase in population.
2. The transformation of a large amount of agricultural land into industrial, commercial, residential and transportation land may lead to a series of environmental problems (e.g. pollution of water sources, deterioration of air quality, piles of garbage, reduction of green areas, etc.) and social problems (e.g. traffic congestion, vehicular traffic jams, noise pollution, shortage of housing, etc.). The only way to achieve moderate development in the PRD during the process of urban development is to carry out scientific and reasonable planning, pay attention to environmental protection, and introduce foreigners appropriately. Only by focusing on environmental protection, introducing foreign population and improving publicity and education can the Pearl River Delta solve its environmental and social problems, harmonize human-land relations and achieve sustainable development.
Xishuangbanna 1, Xishuangbanna annual average temperature of more than 20 ℃, the highest temperature occurs in May each year; precipitation by the monsoon is greatly affected by the whole year is clearly divided into rainy season and dry season. May to October each year from the Indian Ocean prevails in the southwest monsoon, precipitation is more, for the rainy season; January to April prevails from the continental interior of the northeast monsoon, precipitation is very little, for the dry season, and thus become a typical tropical monsoon climate. 2. Xishuangbanna is located in the southern part of Yunnan, south of the Tropic of Capricorn, belonging to the tropical monsoon climate, the average annual temperature of more than 20 ℃, the climate is hot and humid, the Dai live in a bamboo building in order to ventilate the heat, but also to prevent insects and snakes. The Dai people live in bamboo buildings in order to ventilate and dissipate heat, as well as to prevent insects and snakes. The local food crop is rice, and the bamboo tube rice, which is made of rice packed in bamboo tubes and stewed and roasted, is one of the favorite staple foods of the Dai people.3 (2) The primitive rainforests here are well-preserved, and you can enjoy the unique landscapes of the rainforests and the tropical animals. This is a place where ethnic minorities live, and you can enjoy the distinctive ethnic culture of the Dai people. Textbook P63 Activity 1 For a long time, the economy of Xishuangbanna region is mainly based on agricultural production. In the mid- to late 1980s, by virtue of the unique location and resource advantages, tourism has developed rapidly, and its proportion has been increasing, reaching more than 45% at the end of the 1990s, which has become the pillar industry of the region. The development of tourism has led to the development of many sectors, increased employment opportunities and per capita income, improved people's living conditions, and promoted the economic development of Xishuangbanna, and the tourism industry has become an important pillar industry.2. The factors of the decline of tourism are: ① the emergence of neighboring tourist attractions; ② the attractions are scattered, not formed a scale, reception is not international; ③ illegal traders lure customers to shop, affecting the reputation; ④ ecological environment is under pressure; ⑤ some attractions are the same and have no characteristics. 3. Measures to increase the development of tourism: ① the integration of the existing tourist attractions; ② to strengthen the planning and renovation of tourist attractions; ③ to strengthen the management and supervision of tourist attractions; ④ to increase the publicity; ⑤ the development of new tourism projects. Loess Plateau 1, the location and scope of the Loess Plateau: the Loess Plateau from the Taihang Mountains in the east, west to the Usshering Ridge, south of the Qinling Mountains, north of the Great Wall. It spans most or part of seven provinces and regions, including Shanxi Province, Shaanxi Province, Ningxia Hui Autonomous Region and Gansu Province. 2. (1) Distribution pattern of the Gobi, desert and loess: from left to right, the Gobi, desert and loess. Due to the wind force, the wind to the Gobi, the desert in the loess material blowing away, loess in the desert area of the downwind zone accumulation, day after day, month after month, year after year, the formation of the loess plateau. (2) Loess Plateau loess material source of a "wind into the said" based on t ① loess thickness is generally uniform, that loess is blown from the sky, rather than running water; ② loess particles from north-west to south-east is getting finer and finer, indicating that the direction of the flow of material is from north-west to south-east; ③ loess in the ancient soil, indicating that it is not a local rock weathering of the production of the threat, but foreign; ④ mineral composition and Central Asia, Mongolia and other places in the Gobi, the desert mineral composition. Mineral composition and Central Asia, Mongolia and other places in the Gobi, the desert mineral composition is the same, indicating that its source in Central Asia, Mongolia. Textbook P69 Activity 1 The role of surface vegetation (including forests and grasslands) is to maintain soil and water, prevent wind and sand, and reduce soil erosion. Surface vegetation is abundant, local soil erosion is very small; surface vegetation is lacking, local soil erosion is very serious. 2. Loess Plateau soil erosion is serious reasons: ① natural causes: a. terrain: steeper slope, longer ground, strong erosion force of scouring; b. vegetation: bare bare, lack of vegetation protection; c. soil: loose, porous and vertical fissures; d. climate: precipitation is concentrated in July, d. Climate: precipitation is concentrated in July and August, with heavy rainfall. ② man-made causes: a. deforestation and destruction of grass, steep slopes, the destruction of the surface vegetation; b. mining, road construction and other activities to make the surface loose. 3. China's serious soil erosion in the northern part of the North China Plain, Loess Plateau, the upper reaches of the Yangtze River and Yunnan-Guizhou Plateau. These areas have sparse vegetation on the surface or steep slopes and are characterized by heavy rainfall and long rainy seasons. Zones along the Yangtze River1 (1) The topography of the upper reaches of the Yangtze River is dominated by mountains, while the middle and lower reaches of the Yangtze River are dominated by plains and low hills. (2) Different ways of utilizing resources in the east and west along the Yangtze River: ① Can we develop hydropower in the upper reaches of the Yangtze River? Because the water here flows rapidly at the end and the drop is larger. ② We can develop tourism along the Yangtze River because the areas along the Yangtze River are rich in tourism resources. ③We can develop freshwater aquaculture in the middle and lower reaches of the Yangtze River because there are many lakes here. (iv) We can develop inland waterway shipping industry in the middle and lower reaches because the middle and lower reaches of the river are wide and deep. 2. (D The natural resources along the Yangtze River belt are mainly coal, iron, non-ferrous metals, natural gas and hydroelectric energy. (2) Natural resources in the upper reaches of the Yangtze River mainly include coal, natural gas and hydroelectric energy. The natural resources in the middle and lower reaches of the Yangtze River mainly include iron and nonferrous metals. Hydraulic energy of the Yangtze River is mainly concentrated in the upper reaches. Non-ferrous metals are distributed in the middle and lower reaches of the Yangtze River, and are rich in reserves and varieties. The area along the Yangtze River is an economically developed region in China, which plays an important role in linking and radiating the development of China's economy. Textbook P78 activity 1 (1) drawing sketches of the main cities along the Yangtze River and through the railroad line: Chongqing (Chengdu-Chongqing line), Wuhan (Beijing-Guangzhou line〉, Jiujiang (Beijing-Kowloon line), Nanjing (Beijing-Shanghai line), Shanghai (Beijing-Shanghai line). (2) The direction of economic radiation along the Yangtze River is from the zone to the north and south radiation, to the south can reach the southern coast of the Pearl River Delta region, to the north can reach North China, the farthest to the northeast. This integrates the economies of the north and the south and strengthens inter-regional economic cooperation. () ① The non-ferrous metals and hydroelectric resources along the river can be transported in the north-south direction by means of the north-south tributaries and the main lines of transportation; ② The trade along the river can be connected with the Pearl River Delta, North China and Northeast China by means of the main lines of transportation, which promotes the development of trade. I think the proponent is right. The construction of railroads and highways along the river can give full play to the link and radiation of the Yangtze River along the river zone to promote the development of the economy of the east and west, but also to make China's north and south of the economy into one, more conducive to the rapid development of the economy. Textbook P83 activities along the lower reaches of the river zone due to industrial development, densely populated, large electricity consumption. The upstream area is rich in hydroelectric resources and has plenty of electricity. The way of cooperation is to send electricity from the west to the east, to transmit hydropower from the middle and upper reaches of the Yangtze River to the downstream areas to alleviate the problem of energy shortage. The lower reaches are characterized by dense industry, developed economy, advanced technology and strong scientific and technological strength, while the middle and upper reaches are the opposite. The way to collaborate is to respond to the national call for the development of the western part of the country, and to increase financial and technological support for the western part of the country in order to accelerate its economic development. The development and utilization of the Yangtze River has caused a series of ecological and environmental problems. Textbook P85 activity 1 measures to prevent soil erosion in the upper reaches of the Yangtze River: ① construction of the upper and middle reaches of the Yangtze River protection forests; ② planting trees and grasses; ③ retired from cultivation to forests and grasslands and wetlands; ④ prohibit overgrazing; ⑤ construction of retaining dams; ⑤ control of the population, change the concept of. 2. 2. natural lakes reduce the area, flood storage capacity is reduced a return to return to the lake, expand the area of the lake, improve the flood storage capacity of the lake. Plant trees and grasses around the lakes to keep water and nourish water. Large and concentrated precipitation, heavy rainfall - build flood control facilities, such as building or reinforcing reservoirs and rebuilding embankments on both sides of the Yangtze River. 3. Measures to prevent and control water pollution of the Yangtze River: ① government departments to carry out macro-control, management, according to law, and increase publicity and law enforcement; ② control the number of people; ③ prohibit factories untreated slag, waste gas and waste water discharged into the river; ④ industrial upgrading of equipment to completely control the problem of acid rain; ⑤ industry to strive to achieve the recycling of the "three wastes". Textbook P88 Activity
1 Analyze the conditions for economic development in terms of geographic location, natural conditions, resources, land and labor, markets, and technological strength.
2. Take the example of the West-to-East Power Transmission Project.
(1) The energy distribution area and the place of energy consumption are not uniform.
1) coal is concentrated in Shanxi, Shaanxi and western Inner Mongolia, hydroelectric resources are mainly concentrated in the southwest and the Yangtze River, Yellow River, the main reaches of the region; ② energy consumption is mainly concentrated in the energy (power) shortage of economically developed eastern coastal areas.
(2) the significance of the "west to east".4
In order to meet the needs of the national economic development of the power growth, to achieve sustainable development of energy resources and the environment, we must accelerate the development of the southwest and the Yangtze River, the Yellow River, the upper reaches of the rich hydropower resources and coal resources, the transmission of the relatively economically developed eastern coastal areas, the implementation of the development of electric power, "west to east" strategy to promote the economic and social development of the east and west regions, and the development of the power industry. The strategy of "sending electricity from the west to the east" is being implemented to promote the coordinated economic and social development of the eastern and western regions.
(3) The "Western Electricity Sending to the East" project consists of three parts.
(1) hydropower and thermal power from Yunnan, Guizhou and Gui are sent to Guangdong; (2) hydropower from the upper reaches of the Yangtze River is sent to East China; and (3) hydropower from the upper reaches of the Yellow River and thermal power from Shanxi and Inner Mongolia are sent to Beijing, Tianjin and Tangshan.
