We will strengthen infrastructure support in key regions

Build a new forest city surrounded by green sea. The forest space should be continuously optimized to achieve at least one urban forest of more than 1,000 mu in each new plain city, and the green coverage rate of the built-up areas should reach more than 48%. Shunyi New City area, the construction of Shunhe Park, eliminate the blind area covered by the 500-meter service radius of the urban park, improve the quality of green ecological space of the capital's international exchange gateway. In the Daxing New City area, the Central Ecological Park of airport economic zone will be built around Beijing Daxing International Airport, and 1,900 hectares of ecological nodes and ecological corridors along the South Central Axis, Yongding River and important transportation links will be afforested, and the ecological barrier in the south of the city will continue to be strengthened. Changping New City area, the construction of Aobei Forest park, new park area of 207 hectares, to achieve the Hui Tian area, future science City and Wenyu River along the park green organic series. Fangshan New Town area, the construction of Liangxiang University town central landscape green belt park, new city forest park, continue to improve the level of the new city's ecological environment.

4. Protect the green waters and mountains of ecological conservation areas

Firmly establish and practice the concept that green water and green mountains are gold mountains and silver mountains, strictly implement the regulations on ecological protection and green development of ecological conservation areas, strengthen infrastructure support, and build ecological conservation areas into the strategic hinterland of the capital and the golden card of ecological civilization.

We will strengthen ecological protection of drinking water sources. We will protect the water source with Miyun Reservoir as the core, strengthen the protection of the shoreline of various reservoirs, and improve the surrounding environment of reservoirs. Implementation of the Miyun Reservoir water protection Beijing-Hebei joint action to promote the Guanting reservoir water protection project. Complete the reinforcement of existing dangerous reservoirs, eliminate engineering safety hazards, and simultaneously improve the long-term mechanism of reservoir operation management and protection. Focusing on the upstream area of the reservoir, focusing on the ecological conservation area to "clean water down the mountain, clean water into the river into the reservoir" as the goal, to carry out the construction of ecological clean small watershed, the "14th Five-Year Plan" to build ecological clean small watershed of more than 600 square kilometers, the upstream of Miyun reservoir to achieve full coverage, by 2025, the city's soil and water conservation rate of 90%.

Improve the ecological functions of mountain forests. We will continue to strengthen ecological protection and restoration in mountain areas, carry out healthy forest management, and fully protect natural secondary forests. Ecological protection and restoration should be carried out in the Yanshan region, and forest fires and pest invasion should be strictly prevented and controlled. In the Taihang Mountain area, we should strengthen the treatment of abandoned mines and continuously improve the quality of forest stand. In the shallow mountain area, increase the resistance of strong, live rural longevity tree species and color leaf tree species, and create a forest landscape stretching and colorful. We will further strengthen the protection of nature reserves, scenic spots, forest parks, and wildlife habitats. Enhance the ecological landscape along the Great Wall and along the Yongding River.

We will strengthen transport infrastructure. We will make use of existing railway resources to accelerate the construction of projects such as the overall upgrading of Jingmen Line, Menda Line and Tongmi Line, and promote the development of tourism and culture industries along the line. Give full play to the radiating role of expressways in regional development, and complete the construction of national Highway 109 new line expressways, Xitai Road, leisure Assembly North Road and other expressway connection lines. Improve the internal road network conditions in the ecological conservation area, and improve the construction of shallow mountain road projects such as Nanshan Ring Line Phase III and Shuangda Road Phase II.

5. Strengthen the infrastructure support capacity of key functional areas

Firmly seize the opportunity of the "two zones" construction, highlight key points, take points with aspects, give play to the guiding and driving role of infrastructure, and improve the quality and service level of infrastructure construction in key functional areas.

Invigorate the "two zones". We will build a comprehensive transportation system outside the Fourth Embassy Area, complete the first phase of rail transit Line 3 and Line 12, and promote the first phase of Line R4, Liangma Hebei Road, Dongwei Road, Tianwei Road and other projects. Strengthen the external traffic supply of the new national exhibition, and promote the purchase of additional vehicles on Line 15, the Beijing-Michigan Expressway, and the new National Exhibition liaison line. Improve the backbone road network of Jinzhan International Cooperation Zone, and build Dongba Street, Fuyang West Street, Xingba Road and other main roads. Strengthen the port function platform of the pilot Free Trade Zone, promote the construction of multimodal transport facilities in the cargo area of Beijing Daxing International Airport, promote the construction of the East and West hubs of the Capital International Airport and improve and upgrade the existing cargo facilities, and improve the cargo support capacity and transportation efficiency of the airport port.
