January 2017，When General Secretary Xi Jinping inspected Zhangjiakou, he made the decision to “build the capital’s bet365 apuestas source conservation area and ecological environment support area (hereinafter referred to as the capital’s ‘two districts’)，Exploring an ecologically revitalized city in an economically underdeveloped area、Important instructions on the road to strengthening the city through ecology。Zhangjiakou and Beijing belong to the same natural ecosystem，It is a bet365 apuestas source and important ecological barrier for the capital Beijing and even North China，The "Beijing-Tianjin-Hebei Coordinated Development Plan" identified it as an ecological conservation area in the northwest of Beijing-Tianjin-Hebei。Building the "two districts" of the capital is related to the bet365 apuestas source and ecological security of the capital，Related to the promotion of coordinated development of Beijing, Tianjin and Hebei，Related to the successful hosting of the 2022 Winter Olympics。Especially with the Winter Olympics approaching，The world’s eyes will increasingly focus on Zhangjiakou，More and more concerned about its ecological environment。current，How to strive to implement the spirit of the General Secretary’s important instructions，Focus on major key areas，Accelerate the construction of "two districts" in the capital，It has become a major issue that needs to be solved。

　　Determine the spatial structure of land utilization for the bet365 apuestas the capital’s “two districts” as soon as possible，And impose rigid controls。Sufficient ecological space (land) is a rigid requirement and prerequisite for maintaining and ensuring regional ecological security，Zhangjiakou wants to create a veritable "two districts" of the capital，It is necessary to ensure that there is enough ecological space that matches the construction of the "two districts" of the capital。current，At the time of industrialization in Zhangjiakou area、Rapid urbanization development period，To avoid disorderly expansion of urban and rural construction，Ecological space is being squeezed，It is recommended to determine the spatial structure of land utilization for the construction of the "two districts" of the capital as soon as possible: the delineation includes wetland parks、Forest Park、Geopark、Ecological environment support space mainly in nature reserves and biodiversity reserves；With river wetlands、Hu Nao Wetland、bet365 apuestas source conservation space mainly composed of reservoirs, wetlands, etc.；With protective forest、Sand fixation forest、Timber forest、Fruit forest、Native grassland、Green space dominated by artificial grass；With permanent basic farmland、Basic farmland、Agricultural land space dominated by general farmland；Urban and rural construction、Urban and rural construction land space mainly used for transportation facilities construction and independent industrial and mining construction land；Secondary woodland、Barren grassland、Saline-alkali land、Swampland、Reserved space for ecological construction based on bare land, etc.，Strengthening rigid control over the use of land and space，Ensure sufficient land space for the construction of the "two districts" of the capital。

　　Reshape the river and lake ecosystem，Building a new pattern of bet365 apuestas conservation in a virtuous cycle。River and lake ecosystem，It is the symbol of the bet365 apuestas conservation area and the concentrated expression of the bet365 apuestas supply function，Yanghe、Sanggan River、Chaobai River is the mother river of Zhangjiakou，It is also the key to the construction of the capital’s bet365 apuestas conservation area。To ensure a stable bet365 apuestas source in the capital，Accelerate the construction of bet365 apuestas source conservation functional areas in the capital，Degraded river and lake ecosystems must be restored as soon as possible: First, from the overall perspective of enhancing the bet365 apuestas conservation capacity of rivers，Comprehensively carry out the mother river restoration project in the central city of Zhangjiakou and various counties，Restore Yanghe River as soon as possible、Ecological functions of Sanggan River and other bet365 apuestas systems。The second is to strictly control the development intensity of river bet365 apuestas resources，Stop the construction of various types of river diversion canals at all levels，Earnestly protect the sections of the river that have not dried up yet，Securing the Sanggan River、Yanghe、The bet365 apuestas sections of Lightning River and Black and White River will no longer dry up and dry up。The third is to stand at the height of regional sustainable development，Coordinate the Nanyang River Reservoir and Youyi Reservoir in the upper reaches of the Yang River、Cetian Reservoir and Huliuhe Reservoir in the upper reaches of Sangqian River、Yunzhou Reservoir and Lightning River Reservoir in the Chaobai River Basin、The bet365 apuestas resources utilization functions of major reservoirs in the region such as the Huanggainao Reservoir on the Anguli River，Highlight the ecological bet365 apuestas supply function of rivers，Include ecological bet365 apuestas replenishment into the reservoir dispatch plan，Regularly and irregularly supply bet365 apuestas to the downstream river，Ensuring that the downstream reaches of the river end the history of drying up，Building a virtuous cycle of bet365 apuestas source conservation security pattern。

　　Completely eradicate bet365 apuestas source pollution in Yanghe River and ensure the safety of bet365 apuestas supply in the capital.With the construction of Guanting Reservoir in the 1950s，Zhangjiakou has become an important surface bet365 apuestas source for the capital Beijing。Since the 1970s，The state and local governments have been continuously increasing their efforts to control the pollution of Yanghe River, the upstream bet365 apuestas system of Guanting Reservoir。After more than 40 years of hard work，Potential prevention and control in the Yanghe River Basin has achieved positive results，bet365 apuestas quality improved significantly。However, some watershed treatment facilities need further improvement、Improving pipe network supporting facilities、Improve sewage discharge layout and bet365 apuestas environment carrying capacity, etc.。To ensure the safety of the capital’s bet365 apuestas supply，We must be determined to eradicate Yanghe River pollution。First, it is recommended to implement the construction of Yanghe River pollution cleanup and diversion project，Effectively guarantee clean bet365 apuestas、Sewage goes its own way，Creating conditions for county sewage treatment，Laying the foundation；Second, it is recommended to build a special channel for sewage discharge in Zhangjiakou area，Find a way out for urban and county sewage，Realize sewage drainage around the reservoir；Third, it is recommended to comprehensively increase county sewage treatment and recycling，Nothing available for promotion、Before the more mature sewage advanced treatment technology，Creatively build a simple sewage treatment and reuse engineering system at the county and township levels。Use treated gray bet365 apuestas to maximum extent in forest and pasture ecosystems，Reducing pollution pressure in Yanghe River Basin and Guanting Reservoir。

　　Restore large-scale forest and grass ecosystem，Build a strong bet365 apuestas security barrier in the capital。Forests and grasslands are the main components of the capital’s ecological barrier，Restore the forest ecosystem under the dam and the grassland ecosystem above the dam in Zhangjiakou，To show the characteristics of the "two districts" of Zhangjiakou's capital，Building a strong ecological security barrier in the capital is of great significance。In order to effectively expand Zhangjiakou’s forest and grass ecological space，Strengthening ecological environment support: First, we must deepen the development of barren mountains、Barren Slope、Desolate beach、Tree planting in unused areas such as wastelands, secondary forests and grasslands、Afforestation、Growing grass，Restore the native forest from the historical period、Pasture and savanna landscape。Continue to promote the Three-North Shelterbelt with high standards、Protective forest around the capital、Construction of windbreak and sand-fixing forest and other projects。Second, we must further implement the return of farmland to forest and grassland，The light, heat, and soil conditions for agriculture in Zhangjiakou are relatively poor，Does not have the conditions to build a large farmland market，However, due to many large-scale deforestation and grassland reclamation in historical periods，But it has formed a de facto farmland market。Currently，The city’s cultivated land area has reached 13.98 million acres，Per capita cultivated land area 3.15 acres，More than twice the per capita cultivated land area in the country，But due to bet365 apuestas shortage、Cold climate，The area of ​​irrigated land with stable and high yields only accounts for 22% of the city’s total cultivated land。This kind of extensive planting but poor harvest、Inferior farmland that depends on God for food，Neither plays a role in ensuring food security，At the same time, it also occupies a large amount of native ecological space，Intensified ecological disasters such as soil erosion and sand and dust。Both subjective and objective aspects need to be based on the overall perspective of regional ecological security，Determined to adjust the structure of agricultural land，Carry out large-scale construction of poor-quality farmland conversion project to forest and grassland，Expand forest and grass ecological space。Third, we must combine the development of all-region tourism，Promote the construction of protected areas at all levels and types。Add forest park、Wetland Park、Grassland Park and other eco-tourism functional areas，Increase bet365 apuestas source protection areas、The pace of construction of wetland reserves such as Hunao Reserve，Comprehensively improve Zhangjiakou’s ecological environment support and bet365 apuestas conservation capabilities。
