January 2017，General Secretary Xi Jinping made a "build the capital water source conservation area and ecological environment support area (hereinafter referred to as the capital 'two districts') when inspected Zhangjiakou，Explore an ecological city in an underdeveloped area、Ecological Strong City Road "important instructions。Zhangjiakou and Beijing belong to the same natural ecosystem，It is the water source and important ecological barrier of the capital Beijing and even the entire North China，The Outline of the "Beijing -Tianjin -Hebei Coordinated Development Plan" will be determined as an ecological conservation area northwestern Beijing -Hebei -Hebei。Certain the "two districts" of the capital is related to the capital water source and ecological safety，It is related to Beijing -Tianjin -Hebei Coordinated Development and Promotion，It is related to the success of the 2022 Winter Olympics。Especially as the Winter Olympics approach，The eyes of the world will become more and more focused on Zhangjiakou，Pay more and more attention to its ecological environment。Current，How to work hard to practice the important instructions of the General Secretary，Focus on major key areas，Accelerate the construction of the "two districts" of the capital，It has become a major issue that needs to be cracking。

　　Bet365 app download A sufficient ecological space (land) is the rigid requirements and prerequisites for maintaining and ensuring the ecological security of the region，Zhangjiakou wants to create a veritable capital "Two Districts"，It is necessary to ensure that there is enough ecological space that matches the construction of the "two districts" with the capital。Current，Industrialization of Zhangjiakou area、The rapid development period of urbanization，To avoid the disorderly expansion of urban and rural construction，Ecological space is crowded，It is recommended to determine the "two districts" of the capital to build land use space structure as soon as possible: delineation includes wetland parks、Forest Park、Geological Park、Ecological environment support space mainly based on nature reserves and biological diversity reserves;、Lake Wetland、Water sources mainly focused on the wetland of reservoirs; the protective forest、Shatin、Material forest、Guolin、Native Pacific Field、Greenland space mainly based on artificial grass fields; permanent basic farmland、Basic farmland、Agricultural land space for general farmland;、Urban and rural construction space for transportation facilities construction and independent industrial and mining construction land; secondary forest land、Wild grass、saline -alkali land、Marshland、Naked ground -based ecological construction reserved space, etc.，Strengthen the use of rigid control of land and space，Make sure that the construction of the "two districts" in the capital has enough land space。

　　Reshape the river and lake ecosystem，Construct a new pattern of water source conservation of a virtuous cycle。River and Lake Ecosystem，It is a symbol of the water source conservation area and the concentration of water supply functions，Yanghe、Sanggan River、Chaobai River is the mother river of Zhangjiakou，It is also the key to the construction of the water source conservation area of ​​the capital。To ensure the stable water source in the capital，Accelerate the construction of the capital conservation function zone of the capital，River and lake ecosystems that must be restored as soon as possible: First, the global height of strengthening the ability to enhance river water source，Comprehensive development of Zhangjiakou Central City and Mother River Restriction Project in each county area，Restore Yanghe as soon as possible、Sangan River and other water system ecological functions。Second, strictly control the development intensity of river water resources，Discontinue construction of various types of rivers and irrigation canals at all levels，Effectively keep the river section that has not yet dried up，Make sure Sanggan River、Yanghe、Lightning River and Black and White River have water and river sections no longer the phenomenon of dry flow。Third is the height of standing in the regional sustainable development，Nanyang River Reservoir and Friendship Reservoir、Book of Tutian Reservoir and Pugs River Reservoir in the upper reaches of the Sanggan River、Yunzhou Reservoir and Lightning River Reservoir in the Chaobai River Basin、The water resources utilization function of the main reservoir in the Anturi River and other areas，Highlight the River Ecological hydration function，Ecological hydration in the reservoir scheduling plan，Regularly irregularly supply water to the downstream river，Ensure the history of the end of the downstream river section，Construct a virtuous cycle of water source conservation safety pattern。

　　thoroughly cure the pollution of water sources in Yanghe to ensure water supply safety in the capital.With the construction of the government hall reservoir in the 1950s，Zhangjiakou becomes an important surface water source in the capital Beijing。Since the 1970s，The country and local and localities have been continuously increasing the governance of the water system of the upper reaches of the government hall reservoir -Yanghe pollution。After more than 40 years of hard work，The prevention and control of pollution in the Yanghe River Basin has achieved positive results，Water quality improves significantly。But some basin processing facilities need to be further improved、Improve pipe network support、Improve the capacity of sewage layout and water environment carrying capacity, etc.。Make sure to ensure water supply safety，Must be determined to cure Yanghe pollution。First, it is recommended to implement the construction of the pollution and diversion project of Yanghe，Perform the water、Sewage each line，Create conditions for the governance of sewage in the county，Lay the foundation; second, it is recommended to build a special channel for sewage discharge in Zhangjiakou area，Find a way for urban and county sewage，Realize the lower row of sewage around the warehouse; third, it is recommended to comprehensively increase the control and reuse of the county area，There is no available promotion、Before the more mature sewage deep treatment technology，Creatively constructing the county and township two -level simple sewage treatment and reuse engineering system。Maximum the processing of the processing of the treated water in the forest and pastoral ecosystem，Before the more mature sewage deep treatment technology。

　　Large -scale restoration of forest grass ecosystems，Building the capital's ecological security barrier。Forest and pasture are the main body of the construction of the capital ecological barrier，Restore the forest ecosystem under Zhangjiakou dam and the pornographic ecosystem，For the "two districts" characteristics of the "two districts" of the capital of Zhangjiakou，It is very important to build the capital's ecological security barrier。To effectively expand the ecological space of Zhangjiakou forest and grass，Strengthening ecological environment support: First, we must further promote the Mountain、Wild Po、Deep Beach、Tree planting trees that are not available in deserted and second forest and grassland、Forestry、Grass，Restore the native forest of the historical period、Praart and Rare Tree Prairie Landscape。Continue to advance high standards to promote the three north protective forests、Ring Capital Protection Forest、Construction of projects such as windproof and sandwood。Second, we must further implement the return of farmland to the forest and the grass，Zhangjiakou Agriculture's light, heat and soil conditions are relatively poor，No conditions for building arable land cities，However, due to the many large -scale large -scale forests and destruction of grass and destruction of wasteland for many times during the historical period，But it has formed a de facto farmland city。Current，The city's arable land area has reached 13.98 million mu，Per capita arable land area 3.15 acres，It is more than 2 times the per capita arable land area of ​​the country，But due to the shortage of water source、The severe climate is cold，The area of ​​water -poured land that is stable and high -yielding only accounts for 22%of the total area of ​​the city's arable land。This kind of wide species and thin collection、Eating inferior cultivated land with the sky，The role of the food security guarantee cannot be played，At the same time, a large number of native ecological space is crowded，Ecological disasters such as soil and soil loss and wind sand dust。Subjectives and objectives need to stand at the global height of the regional ecological security，Decisive adjustment of agricultural land structure，Large -scale development of inferior cultivated land to return farmland and return forest and grass project，Expand the ecological space of the forest grass。Third, we must combine the development of tourism，Promote the construction of various types of protected areas at all levels。Building Forest Park、Wetland Park、Grassland Park and other ecological tourism function areas，Increase the water source protection area、Building pace of wetland protection areas such as Huyu Reserve，Comprehensively enhance Zhangjiakou's ecological environment support and water conservation ability。
