(D) Distribution characteristics of deserts in Tarim Basin
Teacher: What geographical things do the dotted symbols on the map represent?
Health: Desert (Taklimakan Desert)
Teacher: Why did it form in the Tarim Basin?
Health: omitted.
Teacher: Show me the supplementary explanation of graphic materials.
Note: The yellow area in the figure represents the location of Tarim Basin.
Tarim basin is far from the ocean and surrounded by high mountains. The air flow from the ocean is difficult to reach, the climate is dry, and precipitation is scarce, which is an extremely arid area in China. The Taklimakan Desert, the largest desert in China, was formed in this basin.
(V) Distribution characteristics of water sources in Tarim Basin
Teacher: Why did an oasis form at the edge of Tarim Basin?
Health: omitted.
Teacher: Show me the supplementary explanation of graphic materials.
Turpan, Xinjiang (oasis in the desert)
Oasis refers to the heterogeneous ecological landscape with obvious microclimate effect that can be maintained relatively stably on the basis of large-scale desert background matrix and small-scale biological community with considerable scale. Considerable biological community can ensure the stability and system structure of oasis in space and time; Its microclimate effect ensures that the oasis can have a climate environment suitable for human and other biological population activities, which is conducive to the formation of a biological chain structure for the healthy growth of landscape ecology. In arid areas, oases can only be formed in areas with special water resources guarantee. Oasis only accounts for 8% of Xinjiang's total area, but it concentrates more than 90% of Xinjiang's cultivated land, population and GDP. Agriculture and animal husbandry are developed in oasis area. (Source: 20xx Interactive Encyclopedia)
Teacher: How to ensure the water resources on the edge of Tarim Basin?
Health: Mountain precipitation and melting water of ice and snow.
Teacher: Show me the supplementary explanation of graphic materials.
In a relatively high mountain area, when the warm and humid airflow climbs on the windward slope, the temperature drops, and its capacity to contain water vapor in the air decreases. The water vapor in the air reaches saturation in the mountainside area, which leads to rainfall. After that, the water vapor in the air decreased and the precipitation decreased.
The melting water of alpine snow and ice has the characteristics of seasonal change. In winter, the water vapor in the cold air in the mountains condenses into ice crystals, forming ice and snow. In summer, the temperature rises and the snow melts. The rivers in Tarim basin are all inland rivers, and one of the important components of water source comes from the melting water of alpine ice and snow. Ice and snow melt, replenish in summer and disappear in winter. Therefore, the inland rivers in Tarim basin are mostly seasonal rivers, which are easy to cut off. The rivers indicated by dotted lines on the map data are seasonal rivers.
Teacher: The inland rivers around Tarim Basin are like eyelashes, and the precipitation on the mountains and the water melted by the snow and ice on the mountains are like mascara. In summer, the "eyelashes" around the eyes in Tarim Basin are brushed longer.
This part of design intention leads students to discover the relationship between the main towns, oases, traffic lines, deserts and water sources in Tarim Basin through rich graphic materials and step-by-step questions. It is found that the geographical environment of Tarim Basin depends on special water resources-mountain precipitation and melting water of snow and ice. These special water resources nourish the formation of Xinjiang oasis, human activities on the oasis and the embedding of towns in the oasis.
Second, the development of oil and gas resources in Tarim Basin
(1) Oil and gas resources in Tarim Basin
Teacher: (showing the map data) Most of the roads originally built in Tarim Basin are distributed at the edge of the basin. There are two later built roads running through the Taklimakan desert. What is the main purpose of building these two expressways?
Health: develop oil and gas resources in Tarim basin.
Teacher: supplement the explanation with graphic materials.
Tarim Basin is the largest oil-bearing basin in China with a total area of 560,000 square kilometers. According to the latest round of resource evaluation data of PetroChina and Sinopec, the total proven oil and gas resources in Tarim Basin are about 65.438+0.629 billion tons, of which: the total proven oil and gas resources in Tarim Oilfield of PetroChina are 65.438+0.5 billion tons; The total proven oil and gas resources in Tahe Oilfield of China Petrochemical Company are 65.438+0.276 billion tons, and the total proven oil and gas resources in Baolang Oilfield of China Petrochemical Company are 20xx.94 billion tons. As of 20xx, the total amount of remaining oil and gas resources in the basin ranks first among all major oil and gas fields in China, and the amount of natural gas resources ranks first among more than 500 basins in China. At present, it is still in the early stage of exploration, and its resource potential is huge.
The design intention is to explore the purpose of highway construction across the Taklimakan desert on the map through the progressive problem of the previous plate, which leads to the rich oil and gas resources in the Tarim Basin, and further explains it with graphic materials, so that students can obtain rich graphic information and form a specific understanding of the oil and gas richness in the Tarim Basin.
(2) West-East Gas Transmission
Post-Bar Simulation of Student Activity Forum ── West-East Gas Transmission
Landlord:
On February 24th, 20xx, the National Development and Reform Commission held a meeting on the completion and acceptance of the West-East Gas Pipeline Project in Beijing. After four years' construction and five years' operation, the West-to-East Gas Transmission Project undertaken by China Petroleum successfully passed the national acceptance.
What exciting news!
Floor 1: I dare ask the landlord, what is "West-East Gas Transmission"?
Second floor: The West-to-East Gas Transmission Project refers to the transportation of natural gas from the west of China to the east, mainly from the Tarim Basin in Xinjiang to the Yangtze River Delta.
Third floor: That far? You must have passed many places along the way, right?
4th floor: The West-East Gas Transmission Project is divided into two lines. The first-line project starts from Lunnan oil and gas field in Tarim Basin, Xinjiang in the west and reaches Shanghai and Hangzhou in the east, with an annual gas transmission capacity of 654.38+0.2 billion cubic meters. The second-line project trunk line transports natural gas imported from Central Asia to Guangzhou and Guangxi at Horgos Port in Xinjiang, with an annual gas transmission capacity of 30 billion cubic meters. The West-East Gas Pipeline is the longest and largest natural gas pipeline in China. I have some pictures here, let's have a look!
Fifth floor: Such a big span must be expensive, right?
6th floor: That's right! The total investment exceeds 654.38+05 billion yuan, and some foreign capital has been introduced, making it the most invested gas pipeline in China.
7th floor: "The longest distance, the most investment and the most complicated construction conditions", so why luck all the way?
8th floor: That means a lot! The West-to-East Gas Transmission Project can transport natural gas from Tarim Basin to the east of China. The development of these oil and gas resources not only brings opportunities for Xinjiang's economic development, but also gives play to the resource advantages of the western region. But also eased the energy supply in the eastern region and optimized the energy structure in the eastern region. Do you understand now?
9th floor: The project is so big that it will definitely not have a great impact on the environment?
10 Building: This problem has been considered by the engineering designer! In order to avoid damaging the ecological environment along the west-to-east gas transmission project, the project strictly stipulates that the construction area is 28 meters wide; During the construction, it is necessary to avoid destroying the surface vegetation as much as possible, recycle all the wastes, backfill all the earthwork, and the environmental protection funds along the line account for 3.6% of the total cost!
Pay attention to the construction area defined by Caiqi Yang in the drawing.
Architecture 1 1: economic benefit+ecological benefit = win-win!
/building kloc-0/2: the main line of the second west-to-east gas transmission project has also been completed!
The design is intended for this part of teaching, and an interesting student activity "Forum Post Bar Simulation Show-West-East Gas Transmission" is designed. By asking students to consult materials (mainly from the teaching materials of People's Education Publishing House), presenting materials, explaining the West-East Gas Transmission Project with illustrations, and creating an interesting learning situation for students in the form of network simulation "forum", the major national projects and constructions far away from students are brought closer to topics that students can discuss and comment on. Let students inquire, record and make statements, which will promote students' learning ability in many aspects, turn the knowledge they want to learn into vivid and concrete simulation activities, and learn new knowledge, understand and master in the activities.
Summarize the new lesson
The outline of Tarim basin is similar to human eyes, and it is an important organ of human body, which is called the window of the soul. Tarim basin is also like a precious eye of the motherland. Because of its unique geographical location and topographic factors, a unique pattern of towns, oases and traffic lines has been formed at the edge of the basin, just like the eyeliner drawn by mother's beautiful eyes. The towering mountains around are shaped like orbital brow bones. They are mountain precipitation and melting water of ice and snow, which moisten the rivers in Tarim basin, just like the beautiful eyelashes of the beautiful eyes of the motherland. Some people say that this eye is trachoma because it is full of yellow sand. As we all know, when you open the yellow sand, you will see the deep black pupil under the sand, which is the rich oil and gas resources in Tarim Basin. May the charming eyes of the motherland look to the east of the motherland and illuminate the motherland. May the motherland become more and more beautiful and stronger!

First, the introduction of new courses.
Show courseware:
Please look at the word "Xinjiang". Do you all recognize it? This is the topographic map of Xinjiang. Let's look at interesting place names.
The right half of the word Xinjiang vividly summarizes the topographic characteristics and national defense importance of Xinjiang. Bow is an ancient weapon, and "earth" refers to 500,000 square kilometers of land occupied by Russia. Xinjiang is located in the northwest border of the motherland, far away from the political center, always reminding us to hold our weapons tightly and defend the territory of the motherland. In this lesson, we will walk into the Tarim Basin, a treasure house for understanding the drought in Xinjiang.
Show courseware when entering a new class.
Teaching objectives:
Show the schematic diagram of Xinjiang satellite image and tell the location of Tarim basin.
Tarim Basin is located in the south of Xinjiang, China, and its area is equivalent to that of China. This basin lies between Tianshan Mountain and Kunlun Mountain. It covers an area of 530,000 square kilometers. In the middle of the basin is Taklimakan Desert.
Taklimakan Desert, a desert area in China.
Taklimakan Desert is a desert with an area of 330,000 square kilometers in China. The average annual precipitation does not exceed 100 mm, and the lowest is only about 4-5 mm, which is extremely arid in China.
Cooperative inquiry 1:
1. Read the climate map of Kashgar, analyze the climate characteristics of Tarim Basin, and summarize the climate types of Tarim Basin. Temperature and precipitation in Kashgar
Leng Xia is a temperate continental climate with hot winter, scarce precipitation and arid climate.
2. Discuss and analyze the causes of climate drought in Tarim Basin: show courseware.
Tarim basin is far away from the ocean (land and sea) and is surrounded by tall mountains (terrain). The air flow from the ocean is difficult to reach, the climate is dry, and precipitation is scarce, which is an extremely arid area in China. Taklimakan Desert is a big desert in China, which was formed in this basin.
Cooperative Inquiry 2: Read Figure 8. 18 and discuss the following questions in groups.
Find out the main towns in Tarim basin and tell their distribution characteristics.
Cities and towns are mainly distributed in oases with water sources, and are distributed in a ring along the edge of Tarim Basin.
What are the characteristics of oasis distribution in the observation map? Find out the important river here-Tarim River.
Oasis refers to the green land with aquatic plants in the desert. Oasis is distributed in hilly areas and rivers on the edge of the basin. Oases are scattered and far apart. The small oasis area limits agricultural production; Oases are far apart, which causes inconvenient transportation in Xinjiang and affects economic development.
This paper discusses the relationship between the distribution of towns and traffic lines and the distribution of water sources and oases in Tarim Basin.
Cities and towns are mainly distributed in oases with water sources, and the traffic lines are connected in series with cities and towns, which are distributed annularly along the edge of Tarim Basin.
There are two roads running through the Taklimakan desert. Guess why these two roads were built.
It is mainly used for the development and utilization of oil and gas resources in Tarim Basin.
