13.2.1 Classification and Evaluation of the Current Status of Urban Land Use
(1) Classification of the Current Status of Urban Land Use
The basic basis for carrying out the survey of the current status of urban land use and compiling the map of the current status of urban land use is the classification of the current status of urban land use. Whether or not the classification is scientific and reasonable is directly related to the results of the survey of the current status of urban land use and the value of the related information. This urban land survey implemented the GBJ137-90 promulgated by the state, that is, "urban land classification and planning and construction land standards", and formulated the following classification principles:
(1) Urban land classification is based on the premise that it is suitable for the needs of urban planning, and aims at scientifically reflecting the nature of various types of land and its structure, as well as taking The current use of the land, the nature of use as the basis for classification to determine the level.
(2) According to the meaning and subordination of the relevant standard level classification, a three-level classification system of large, medium and small categories is established in turn.
(3) The urban land use classification adopts a mixed code of English letters and Arabic numerals, with the major categories expressed in English letters, and the medium and small categories expressed in Arabic numerals in the lower right corner of the major categories' English letters.
(4) The urban land use classification and designation implement the provisions of "Table 2-0-5" in GBJ137-90.
Based on the principle of classifying the current status of land use in Zhangjiajie City and the sign of remote sensing interpretation of land use categories, using GBJ137-90 as the guideline, the three-level classification and unified coding was adopted, and finally 10 major categories of the first level, 37 intermediate categories of the second level, and 9 sub-categories of the third level were identified (Table omitted).
(2) Evaluation of construction land and land use structure
(1) Evaluation of construction land
Using computer statistics and comparing with the planning per capita single construction index of Article 4-2-1 of GBJ137-90, the situation of Zhangjiajie City's construction land is as follows: the per capita residential land use of 46.38 m2/capita exceeds the index (18.0~28.0 m2/capita); Per capita industrial land 3.60 m2/person is less than the indicator (10.0～25.0 m2/person); per capita road and square land 7.73 m2/person is in line with the indicator (7.0～15.0 m2/person); and per capita public *** green space land 5.37 m2/person is less than the indicator (≥7.0 m2/person).
(2) Evaluation of land use structure
Residential land: the area of residential land is 293.5 hectares, accounting for 47.60% of the built-up area, and residential land occupies the first place in the urban land, exceeding the national standard that residential land accounts for 20% to 32% of the built-up land. The total area of residential land in the third and fourth categories was 264.7 hectares, accounting for 90.19% of the area of residential land. Calculated from the per capita residential land is 39 m2/person, the land use index is high, but due to most of the low-rise buildings, it makes the actual residential land utilization rate is not high, and the per capita housing area is low, therefore, it is suggested that the relevant municipal management department should build multi-storey unit-type residential houses appropriately in the future.
Industrial land: Zhangjiajie's major factories are located in the south of the city, including artificial board factories, chemical factories, cement factories, chemical second factories, and paper factories. The city's spring and summer seasons the dominant wind direction for the southeast wind, when the factory emissions of smoke and dust on the urban areas have a greater impact; fall and winter seasons the dominant wind direction turns to the northwest wind, when the factories in the south of the city on the urban areas have less impact on the urban areas, affecting the urban areas is the urban life chimney emissions of smoke and dust. The city's industrial land area of 22.8 hectares, accounting for 3.69% of the built-up area, not exceeding the national standard of 15% to 25%.
Road and square land: the city's road and square land area of 48.9 hectares, accounting for 7.94% of the built-up area, basically reached the national standard of road and square land accounted for 8% to 15% of the built-up area of the standard lower boundary. Urban roads were lattice-shaped distribution, with the ring road and the main road as the framework, secondary roads for the network, the overall constitute a vertical and horizontal intertwined more developed highway transportation system.
Green space: the city's green space is 50.0 hectares, accounting for 8.10% of the built-up area, has reached the national standard that green space should account for 8% to 15% of the built-up land. Surrounded by mountains on all sides, the city has plenty of room for maneuver in opening up green space, and along with the development of the city's scenic tourism industry and the expansion of the urban area, urban greening and green space construction will be rapidly advanced.
Land utilization rate: the city's unutilized land area is 66.9 hectares, accounting for 5.2% of the total area of the survey area. The unutilized land mainly consists of slope land along the river bank and local gray rock bare land. The survey area contains 94.8% of utilized land, so Zhangjiajie City has a high land utilization rate.
13.2.2 Atmospheric and Surface Water Pollution
(I) Air Pollution Sources - Chimneys
The scope of built-up areas controlled by aerial photography*** deciphered 13 chimneys of cement and brick structures (Table 13-1), of which there are 9 industrial chimneys and 4 domestic chimneys. Although the number of distributed chimneys in the city is not large, their emissions have a greater impact on the air quality in the city due to the small urban area and the fact that they are all within the built-up area controlled by aerial photography.
Table 13-1 Zhangjiajie City, the main sources of air pollution and exhaust emissions table
(B) sewage outlets and sewage flows
Through the aerial film interpretation, data collection and field surveys were informed that the following sewage outlets and water pollution zones in the urban area were identified.
(1) Ganxi River outfalls on both sides of the river: Located on both sides of the Ganxi River in the north of Xianrenxi Reservoir at the periphery of the southwestern part of the map area of 2 km, the sewage discharges of paper mills, chemical factories and other units of a number of sewage discharges constitute a group of sewage outfalls that discharge industrial wastewater into the Ganxi River, with an annual discharge of 600,000 tons, and with the main pollutants of Chemical Oxygen Demand (COD) and suspended solids.
(2) Zhangjiajie railroad outfall: located in the southern part of the city along the north side of the Jiao Liu Railway distribution of Zhangjiajie Chemical Factory, Zhangjiajie Artificial Plate Factory, Zhangjiajie South Railway Station (Train), and other units of the sewage outfalls constitute a group of outfalls to the industrial wastewater, mainly through the sewage outfalls in the Heron Bay at the river, with annual discharges of 300,000 tons of major pollutants for the suspended solids and cadmium.
(3) Ximen Creek sewage flow: Ximen Creek's open water flow section in the aerial film shows a 3-5 m wide brown and dark green curved band image, obviously characterized by polluted water. In fact, the creek has been turned into a sewage ditch in the urban area. The creek is discharged with domestic wastewater and part of industrial wastewater, and 4.5 million tons of wastewater is discharged into the river through the Ximen Creek estuary every year, with the main pollutants being chemical oxygen demand (COD) and suspended solids. The discharged wastewater forms a tongue-shaped polluted flow 10-15 m wide and more than 150 m long in the river water body near the north bank, which is shown as a gray strip on the aerial film.
(4) Dongmenxi Sewage Stream: The water body of Dongmenxi is dark green, gray-green and other dark colors on the aerial photographs, indicating that it is a sewage stream. Mainly for the urban area discharged into the domestic wastewater and industrial wastewater, 3 million tons of wastewater discharged into the river each year, the main pollutants are chemical oxygen demand (COD) and suspended solids. East Gate Creek discharged into the sewage in the river near the shore to form a 10-20 m wide, up to 100 m long pollution belt (aerial film on the gray, brown-green strip).
13.2.3 Classification of green areas and greening coverage
(1) Classification of green areas and current greening status
According to the Ministry of Construction's Urban Construction [1993] No. 784, "Provisions on Urban Greening Planning and Construction," and the types and distribution of green areas that specifically exist within the city, the green areas within Zhangjiajie were classified into 7 categories, and through the remote sensing decipherment of the current greening status of Zhangjiajie and the outreach survey, the respective areas of the 7 categories of green spaces in the city and their combined areas were determined (Table omitted).
(1) Public **** green space (GN1): parks, small gardens, street green spaces, etc. open to the public and the waters within their boundaries.
(2) Unit-attached green space (GN2): green space attached to factories, organizations, schools, hospitals, troops and other units and public facilities.
(3) Residential green space (GN3): green space within the residential area excluding district parks and street trees.
(4) Production green space (GN4): nursery land for producing seedlings, turf, flowers and seeds for urban greening.
(5) Protective Greenland (GN5): forest belts and greenlands used for isolation, health and safety
(6) Scenic Forestland (GN6): forestland in the city that relies on natural landforms to beautify and improve the environment.
(7) Road Greening Land (GN7): Greening of boulevards and land covered by the vertical projection of the crowns of street trees within the city.
The total area of natural color aerial photography control greening map spots in Zhangjiajie City is 783.75 hm2, and the total greening area is 136.90 hm2. The order of each type of greening land in terms of its proportion is as follows: unit-affiliated greening land GN2 (41.7%), public **** greening land GN1 (24.8%), greening land in the residential area GN3 (23.0%), greening land for roads GN7 (4.1%), Scenic Green Space GN6 (2.5%), Protective Green Space GN5 (2.4%), Production Green Space GN4 (1.6%).
(ii) Greening Coverage Rate
After calculating the area of each greening plot and the area covered by greening, the number of plots, the area of green space, and the area of the plots included in each of the eight grades of greening coverage in the range are categorized and counted respectively (Table 13-2). Based on the number and distribution of patches included in the greening grading of this table, a remote sensing interpretation map of the current greening status in Zhangjiajie City, Hunan Province was prepared.
According to the Ministry of Construction, Jiancheng [1993] No. 84 document on the current state of urban greening statistical indicators, the urban green coverage, urban green space rate and per capita public **** green space and other three indicators in the built-up area within the control of aerial photography to be calculated.
Through the investigation of the current greening situation in the built-up area of the city and the results of the relevant data statistics and the national urban greening standard comparison and analysis, the following evaluation is made: per capita public **** green space 21.63 m2/person, which meets and exceeds the national standard (10 m2/person); and the greening coverage rate of 17.47%, and the national standard (30%) there is still a certain gap.
Table 13-2 Statistics of greening grading and the area of green space and map spots in Zhangjiajie City
13.2.4 Tectonic activity and stability zoning
(1) Neotectonic and seismic activity
(1) Neotectonic activity: According to regional data, it is presumed that since the redevelopment of the region, the region has been under the general uplift and the extrusion of the north-east-south-west direction. Under the action of the stress field, the early rupture re-activation, to tensile, torsion-based, of which the Wangjiajie - Ancient Bay rupture zone activity is the most significant. The fracture zone, which crosses the map area in a north-east-east direction, is the middle part of the Huayuan-Dayong-Cili fracture zone, which has been active for a long time since the Mesozoic Era. The fracture zone is also an important heat flow value anomaly and new tectonic activity zone in the province, and there are as many as 11 hot springs distributed along the fracture zone.
According to the field observation, the rift zone has obvious signs of activity since the Cenozoic era, and the geomorphology macroscopically shows a rift valley with a rift valley, with a strike direction of 70° north-east to east, and the total distance between the breaks is big in the west and small in the east, and the west is bigger than 2800 m, while the east side is less than 1000 m, which is of the nature of lifting and slanting. Microgeomorphologically, small gullies develop along the secondary rupture surface within the rift zone. On the outcrops, there are fault muds of varying widths on the main and secondary rupture surfaces, in which flakes and strips of debris are slightly oriented, suggesting that the fault zone is still active since the Cenozoic era, and there is intermittent rebound at the same time.
(2) Seismic activity: According to historical records: 18 earthquakes have occurred in the area of Huayuan, Yongshun, Dayong and Cili since 1604. Figure area is located in the middle of the zone, the history of the earthquake occurred or was affected by 12 times, most of them are non-sensory earthquakes, only two for the felt earthquake. The largest one occurred on December 28, 1786 in Dayong (present-day Zhangjiajie City), with an intensity of 6 degrees and a magnitude of 5.1, causing mountains to crumble and rivers to flow backward for dozens of miles due to blockage. The earthquakes in the map area are tectonic earthquakes, and the source of the earthquakes is the north-east-east oriented rupture zone (i.e., the Wangjiajie-Ancient Bay rupture) of Huayuan-Dayong-Cili. The rupture zone is highly active in the near future, and according to the information of the relevant departments, Zhangjiajie City in the map area is designated as a 6-magnitude seismic intensity zone.
(2) Stability zoning
The main factors for stability evaluation are:
(1) Tectonic stability: mainly the intensity of present-day activity of the fracture structure and its relationship with the frequency of seismic activity;
(2) Stability of rock and soil: mainly the characteristics of bedrock rock and loose sediment grain size and cementation characteristics;
(3) Ground stability: mainly rock winds and winds, but also the stability of the ground;
(4) Stability of the soil: mainly the rock winds and winds, but also the stability of the ground. ) ground stability: mainly refers to rock weathering, denudation, soil erosion, collapse and landslides.
Tectonic stability is the main factor in determining stability, is the main basis for the first level of stability zoning, only in the case of the same tectonic stability, the latter two under certain conditions can rise to become an important factor.
From the analysis of regional geological and tectonic background, this area is located in the middle of the northwest Hunan landmass, and is divided into Jurassic fold deformation area and Garidong fold reverse deformation area by the boundary of Huayuan-Dayong deep and large rupture (with the Wangjiajie-Ancient Bay Fracture Zone as a section of it), while the Wangjiajie-Ancient Bay Fracture Zone is the rupture zone which has long time activity since the Mesozoic era, so according to the stability zoning factors and evaluation principles, the region is divided into three zones: (Ⅰ) sub-stable zone; (Ⅱ) more stable zone; (Ⅲ) stable zone.
13.2.5 Motorized and Non-motorized Traffic Flow
(I) Motorized Traffic Flow
Through aerial film measurement and calculation of motorized vehicles in the road, the average daily (10:00-15:00) bidirectional flow rate of motorized vehicles on the 13 main and secondary roads in Zhangjiajie City, and daily (10:00-15:00) bidirectional flow rate of motorized vehicles on the 14 intersections in Zhangjiajie City were determined. (10:00～15:00) two-way flow rate (Table 13-3). The remote sensing interpretation map of traffic flow in Zhangjiajie City, Hunan Province was prepared.
Table 13-3 Zhangjiajie City, Zhangjiajie City, the main intersections of two-way motor vehicle traffic statistics
(B) non-motorized traffic
Through the aerial piece of road non-motorized measurements, calculations and tests to determine the Zhangjiajie City, urban areas of the 13 main and secondary non-motorized daily (10:00 ~ 15:00) two-way average flow of non-motorized 14 intersections day (10:00 ~ 15:00), and day (10:00 ~ 15:00) non-motorized. 10:00 ~ 15:00) bidirectional flow (Table 13-4).
13.2.6 Building Density Grading and Types
(I) Building Density Grading
Based on the interpretation and calculation, the building density in Zhangjiajie City can be classified into seven levels. According to the computerized video screen interpretation and comparison with the building density of similar "sample areas", the building density of each type of plots is calculated (Table 13-5).
Table 13-4 Zhangjiajie City, the main intersections of non-motorized daily two-way traffic statistics
Table 13-5 Zhangjiajie City, the percentage of building density map spot statistics
(2) building density type
(1) high-density building area: mainly refers to the building density > 50% of the area (or spot), the total area of the building area of this category 132.40 hm2, accounting for 19.80% of the total built-up area of the map area, mainly distributed in the residential areas along both sides of the river and the residential areas in front of the mountains in the north of the city. This kind of building area is mostly low-rise old-style buildings with small floor area ratio, small spacing between buildings, narrow roads and poor infrastructure. In addition to retaining a part of the old building area with cultural relics and tourism value reflecting the characteristics of the national style, it should be gradually renovated or planned for reconstruction to make full use of the urban land resources, increase the building floor area ratio, and improve the urban environment. Its construction should reflect the style of the scenic belt along the river.
(2) Medium Density Building Area: It mainly refers to the area (or map spot) with a building density of 25.01% to 50.00%, with an area of 292.81 hm2, accounting for 43.80% of the total building area of the map area. This kind of building area is mainly distributed in the main urban area in the north of the map area and along the railroad in the south, it is the building area which has been built through formal planning and design, mainly for the authorities, schools, factories and commercial and new-style residential areas, mainly low and medium-rise buildings, and there are also newly constructed high-rise buildings, with a more reasonable layout, fuller facilities, and a better environment, which is the main building area of Zhangjiajie city nowadays, and the main carrier group of the economy and culture.
(3) low-density building area: building density <25.00% of the area (or map spot), with a total area of 243.32 hm2, accounting for 36.40% of the total area of the building area of the map area. Its main urban parks, river south of the municipal government seat Nanzhuangping Development Zone, civil aviation summer villa, southern scattered residential housing and so on. The construction of new areas in this category represents the development and future of Zhangjiajie City's architecture, and it can be seen from the remote sensing images that these are some of the neighborhoods planned and designed with brand new concepts. For example, in Nanzhuangping New District, a neat and wide network of high-grade cement roads has been built, and the outline of the district is already visible. There is a large area in the south of the zero construction area is now cultivated fields, vegetable fields and fish ponds, is now the city's vegetable supply base, such as the consideration of the base outward, coupled with the village community planning and transformation, will be able to provide a large area of building land for the expansion of the urban area.
13.2.7 Urban Tourism Resources Development
Zhangjiajie City not only has extremely rich natural tourism resources such as Wulingyuan and the sandstone peak forest scenery of Tianzishan Mountain, but also, as can be seen from the results of remote sensing surveys, the urban area of Zhangjiajie is also rich in tourism resources, which are mainly characterized by historical, modern, and contemporary humanistic landscapes.
Zhangjiajie was founded as a city because of tourism, and it also relies on tourism development to develop the city. Since the founding of the city, the municipal government formulated the "tourism-driven strategy" towards the goal of "building Zhangjiajie into a well-known tourist destination at home and abroad" (Jiang Zemin, March 28, 1995), strengthened the planning and opening up, and gradually transformed the advantages of tourism resources into tourism resources. It has strengthened the planning, increased the opening to the outside world, and gradually transformed the advantages of tourism resources into the advantages of tourism economy. In the urban area, the main thing is to increase the investment and construction of tourism facilities, complete the construction of the railway station, the Lotus Airport, the new second bridge over the river and other key projects, the development of telecommunication, radio and television and other information industries, road traffic, greening and other municipal construction has also been rapidly improved, the sound tourism institutions, tourism education, a number of new tourist hotels and shopping malls, the ecological environment has been governed and protected. All this has greatly enhanced the function and role of Zhangjiajie urban tourism center.
Some of the major tourist resources in the city have been protected and developed, such as the famous Puguang Zen Temple and Xiang-E-Chuan-Qian Soviet Memorial Hall, which have become must-see places. However, some other resources may not have been included in the planning, yet to be developed.
(1) About the old city wall: According to the aerial photos in the 1950s, the old city wall, which reflected the history of Zhangjiajie and was of great tourist value, was still intact after the liberation, but unfortunately it was demolished in the process of the later construction of the city, and was built into the present city wall road. In our investigation, found that a corner of the southeast section still exists, so it is recommended that: ① this section of the ancient city wall, should be protected by the Department of cultural relics protection, not allowed to be damaged; ② organization of the relevant departments to carry out surveys, planning, project development, restoration of the wall of the ancient city of the original; ③ in the city wall to build a reflection of Zhangjiajie's ancient city of the style of the pavilion.
This project, if developed, I believe will add a new scenery to Zhangjiajie's city tourism, adding an ancient city rhyme.
(2) on Nanzheng Street, along the river street: near the river Nanzheng Street, along the river street area is still intact with the old residential houses and old stores, it used to be a bustling commercial center, is with the characteristics of the ancient city style. It is suggested that this ancient commercial street according to the Ming and Qing Dynasty style unified planning, refurbishment, restoration of the original appearance of the ancient street. In this operator can wear Tujia, Bai, Miao and other ethnic costumes, can be built theater, teahouse as Dayong Yang opera, Nuo wish play, drums, swinging hand dance, embroidery, pick flowers, paper-cutting and other folk performances of the venue. Nanzheng Street, along the river street of the original appearance of the ancient street once restored, is bound to become another tourist hotspot in the urban area of Zhangjiajie City.
(3) on the Tianmen Cave aerobatics competition: "99" Zhangjiajie aerobatics show at home and abroad caused a huge sensational effect, the special flight competition brings people to the development of tourism resources, new ideas, new forms, new content.
First, this is an investment by the Zhangjiajie Yellow Dragon Cave Tourism Company to host the event, changing the previous practice of the whole government to take over, this organization is the first in the province, for the future of similar large-scale activities to provide a new way of thinking.
Second, the airport's superior flight conditions and Tianmen Cave's peculiar natural conditions cleverly combined together, successfully held a flight adventure show, which fully proves that in the realization of the optimal allocation of tourism resources integrated combination of the masses in the unlimited imagination and creativity.
Thirdly, the choice of time for the special flight race is also praiseworthy. It is in the off-season of tourism, this move will attract tourists from all directions to Zhangjiajie, forming a new tourism boom. This activity reveals how to break through the limitations of climatic conditions, fully develop and utilize resources, so that tourism here thrives in all seasons.
13.2.8 Zhangjiajie City in Historical Changes
(1) Dayong County Town in the 1950s
The first remote sensing image of Dayong County Town (Yongding Town) after liberation was obtained by aerial photography in 1958, which truly recorded the changing face of the county town in the early liberation period. As can be seen from the image, the ancient city wall of the Qing Dynasty is still intact, and the city retains the basic architectural pattern consisting of the ancient city pool and the commercial area along the north bank of the river. The new changes are the widening of roads and the construction of a number of infrastructure such as government offices, the building area expanded by 0.54 km2. external transportation is still mainly river shipping (built in 1951, the South Gate dock). 1953 Yongshun to Dayong highway opened to traffic (through Jishou, Yongshun).
(2) Dayong County in the early 1980s
The second remote sensing image taken by aerial photography in 1980 showed a great change in the appearance of the county.
Changes in transportation conditions: In 1978, the Jiao Liu Railway passed through the south of the county in a nearly east-west direction, setting up Dayong South Station and Dayong North Station, which led to the construction of the station area and the urban area. Dayong South Station is a mixed passenger and cargo station mainly for freight transportation, and it is the distribution point of goods for the border area of Hunan, Hubei, Sichuan and Guizhou provinces, forming a transportation pattern mainly by railroad.
Development of urban construction: most of the ancient city wall was demolished in 1978, and the wall road was reconstructed along the northwestern section. 1980 reconstructed north-south streets include Nanzhengjie, People's Road, Qiba Road, Beizhengjie, and Daqiaoxiao Road, etc. East-west streets include Along Road, Jiefang Road, Tianmen Road, and Chongwen Road, etc. The total length of the reconstructed streets is up to 1,000 kilometers. The total length of the reconstructed and expanded streets reaches 8160 m, the width of the streets is 20~25 m, the road area is 255.5 mu, or 17 hm2. The urban area expands to the east and west, and the new building complexes appear in the southern part of the river centered on the southern and northern railway stations, the buildings have been constructed with reinforced concrete structures, and the urban building area has reached 1.29 km2 and the number of the population has reached 26,173 people.
(3) Present-day Zhangjiajie City
The natural color image map of Zhangjiajie City obtained by using micro ultra-low altitude aerial remote sensing technology is the third aerial remote sensing data in the history of Zhangjiajie City, which reflects in detail the new appearance and scene of today's Zhangjiajie City.
Rapid expansion of urban area: The speed of urbanization is accelerating, the urban area is expanding dramatically, and the population is increasing greatly. According to the statistical data of remote sensing survey on the current situation of the land of this topic, the built-up area of the mapping range is 6.16 km2, and the built-up area is 4.78 times as large as that of 1980, 11.41 times as large as that of 1954, and 18.12 times as large as that of the pre-liberation period. The population of the built-up area is 63,300 people.
The rapid development of urban construction: the new municipal party committee compound, the municipal government office building and the municipal construction committee, traffic control and other municipal organs building; the new Zhangjiajie Lotus Airport, Zhangjiajie Railway Station; a number of cultural and educational facilities such as the new Wuling Higher Education College, a number of new factories; a number of new roads, bridges such as the Meridian Road (for the first-class asphalt road), Lingshiyuan Road, the teaching ground road, the Airport Road and the river. Guanyin Bridge, etc.; a large number of new tourist hotels, trade buildings, farmers' markets, tourism management, tourism services; a number of new residential areas and modern-style accommodation buildings.
After just over ten years of construction, now Zhangjiajie city has become a modern tourist center with a certain scale, sound management institutions, more developed modern transportation, urban utilities supporting.
13.2.9 Suggestions for the planning of the built-up area of Zhangjiajie City
One of the ultimate purposes of this project to carry out remote sensing surveys of the urban environment and resources is to provide a scientific basis for the municipal government's decision-making departments to formulate future urban construction plans. The current planning and design of Zhangjiajie City should first consider the following issues can be summarized:
Build the second class residential area, river pollution urgent treatment;
Widen the ring road in the northern part of the city, the construction of flood control cement embankment;
Planting trees and plants greening the city, accelerating the development zone of the building;
Changing the history of the inheritance of the creation of a new content of tourism;
Establishment of remote sensing monitoring stations
The city has been in the fast lane of information.
Specific planning recommendations are summarized in the following nine articles:
(1) Renovation of the city's three and four types of residential land, the construction of two types of residential land, mainly medium-rise buildings, and then build a residential district with a beautiful environment and complete supporting facilities.
(2) Treating surface water pollution in the first stage, strictly prohibiting the discharge of domestic sewage and industrial wastewater into the river and its tributaries. Dredging the river, building swimming pools, so that the urban area of the river section of the river become playful beaches and waters. At the same time, the energy structure of residential production and living fuels should be gradually transformed to manage man-made air pollution.
(3) for the river across the city, should improve its flood control dyke construction, urban areas on both sides of the river should be all changed from earth dykes to cement dykes, which is an important initiative to prevent floods and mitigate disasters.
(4) in the construction of urban transportation system, first of all, should be expanded in the north of the city by the Meridian Road, Lingshiyuan Road (North), A Long Road, Tianmen Road (West), such as the composition of the triangular loop. The loop of the north line, the east line has been a high-grade pavement, the construction of the southwest line of the widening of Tianmen Road, A Long Road can complete the construction of the loop. The completion of the loop not only ease the traffic pressure in the city, but also created the first beautiful scenery into the city.
(5) the development of urban areas in the north, west and south, along the edge of the city planting scenic forests, the construction of forest parks; the city's main streets to replenish street trees, increase green space, hedges and green islands; on both sides of the river construction of green scenic belts along the river. Make Zhangjiajie City become a veritable green eco-city.
(6) Remodeling the high-density low-rise old-style buildings in the urban area, expanding the planned medium-rise-oriented buildings in the medium-density zone, and accelerating the construction of the Nanzhuangping Development Zone in the low-density zone. In addition, Zhangjiajie city built-up area of the expansion and development of the lot are in the "sub-stability zone" range, so the building design of the construction of new areas should be considered seismic factors.
(7) the city's history of early buildings of the ancient city wall and the ancient commercial street is a valuable historical heritage, should be inherited, protection, development, so that the ancient city, the ancient street rejuvenation "youth", become a new tourist hotspot. Enhance the city's historical and cultural taste, so that the "humanities landscape" and "natural landscape" two kinds of tourism resources, intermingled, integrated.
(8) Zhangjiajie aerobatic show provides new ideas for the development of urban tourism resources, so it is recommended to carry out scenic tours at the same time, more innovative forms of colorful tourism activities, in order to accelerate the development of urban tourism.
(9) The construction of "urban environmental resources remote sensing monitoring system" with the technology of "three S's (RS, GIS, GPS)" is included in the construction plan of digitalized Zhangjiajie City, which will make Zhangjiajie City's tourism economy and social development enter into the fast lane of information highway in the new century. The fast lane of the information highway in the new century.
