We will work hard to improve the quality of infrastructure services

Strengthen the implementation of standards and norms. Focus on strengthening the implementation of standards and norms in the fields of municipal infrastructure, urban public transportation, information infrastructure, resource conservation and environmental protection, as an important basis for planning and design, investment and construction, operation and management, and provide support for improving the level of urban fine management.

3. Create high-quality ecological living space

We will further expand ecological Spaces such as rivers, parks and green Spaces, improve the living and working environment of citizens, and improve service functions such as recreation, parent-child and sports according to local conditions, so as to provide high-quality and inclusive ecological Spaces for citizens to enjoy nearby.

Improve the pattern of water ecology. We will intensify the battle against clear water, accelerate the treatment of confluence overflows and initial stormwater pollution in central urban areas, strengthen regulation, storage and purification, control the mixing and misconnecting of rain and pollution, and upgrade 100 kilometers of pipe networks in accordance with local conditions. We will further improve the sewage collection and treatment capacity in urban areas, continue to promote the construction of sewage treatment facilities in new cities and towns, build and rebuild 1,000 kilometers of sewage collection pipelines, and basically achieve full coverage of sewage collection networks in built-up areas. To open up the links between river and lake systems, build a water network system with river basins being coordinated, multi-line connections, multi-layer circulation and ecological health, enhance the mobility of river and lake water bodies, improve the self-purification capacity and pollution absorption capacity of water bodies, improve the overall level of the water environment in the central urban area, and form a pattern of "three rings of blue water around the capital". To study the ecological water quantity and water source guarantee scheme of key river channels, ensure the ecological water use of key rivers and lakes, and increase the regeneration water to supplement the ecological water use of river channels. The breeding and release of suitable species should be carried out in rivers and lakes where conditions permit, so as to maintain the ecological balance and optimize the water environment.

Expand the public's hydrophilic space. Continue to expand the hydrophilic area to better meet the various hydrophilic needs of citizens such as leisure, entertainment and viewing experience. The Qinghe River, Bahe River, Tonghui River and other urban river and lake landscape upgrading projects will be implemented to improve the design quality of river landscape and hydraulic buildings. By 2025, the length of landscape water system in the central urban area will reach 350 kilometers. Relying on the construction of the Grand Canal Cultural Belt, we will accelerate the construction of supporting facilities such as waterways, locks and wharves along the route, gradually restore the landscape of the historic waterway, and realize the navigation of the whole section of the North Canal, the Tonghui River, the Liangma River, and some sections of the Chaobai River. Further enhance the accessibility and openness of waterfront walks in built-up areas, improve the supply of diversified hydrophilic services, set up fishing, skating, kayaking and other service areas according to local conditions, and realize the opening of local fishing areas and skating rink in rivers and lakes.

Improve the quality of parks and green Spaces. We will improve the system of community parks, urban parks and country parks, and develop "growth parks". Through the construction of small and micro green Spaces and pocket parks, expand community green Spaces and realize open door green. Seven first green barrier urban parks, including Nanyuan Wetland Forest Park and Aobei Forest Park, have been built to complete the "One Green Barrier Urban Park Ring", and 10 second green Barrier country parks, including Wenyu River Park and Chaobai River National Forest Park, have been added, and the "Two Green Barrier Country Park rings" have been continuously improved. The functions of existing parks have been upgraded in an orderly manner, and more than 50 "all-age friendly" parks have been transformed into green Spaces. According to the needs of citizens, cultural facilities, sports venues, parking, emergency shelter and other functional facilities are set up according to local conditions. Combined with new technologies such as smart scene application, 30 demonstration natural recreation places of different types have been built. By 2025, the city will achieve 1,200 hectares of new urban green space, the urban green coverage rate will reach 49%, and the coverage rate of the 500-meter service radius of the city's park green space will reach 90%.

Improve the greenway network. Overall planning of river and lake water systems, parks and green Spaces, slow traffic and other Spaces, further improve the urban greenway network, build a municipal greenway system of "one core, two rings, five belts, and ten districts", and further enhance the systematic and connectivity of the city's ecological space. The Yongding River, Chaobai River, Tonghui River and other waterfront greenways, the Chaoyang Shuangao Green Way and the Xishan Green Way have been completed, and 350 kilometers of new urban greenways have been added. Relying on the municipal greenway node, 44 star-rated greenway service stations have been built to further improve the greenway service function. In the countryside and mountain areas, we plan to build a "hundred thousand" forest trail system, build a 100 km forest recreation trail connecting the mountain plain, 10 forest marathon trails, 100 10 km fitness trails, and 1,000 3-5 km mini trails, and create a distinctive full, half and mini marathon track.
