We will strengthen infrastructure support in key regions

Build a convenient and smooth comprehensive transportation system. Gradually build the backbone rail transit network of Beijing's urban sub-center, realize the Beijing-Tang intercity traffic operation, improve the overall suburban railway line, and accelerate the construction of rail transit lines such as Pinggu Line, Line 6 south extension, and Line M101. We will strengthen road traffic links with the central urban areas and new cities, and complete projects such as the widening and renovation of the Beijing-Harbin Expressway, Jiude Road and Chunming Road. Effectively darning the sub-central space of the city, completing the transformation project of the East Sixth Ring Road into the ground. We will improve the internal road network of Beijing's urban sub-center, and complete projects such as the east extension of Canal East Street and Wansheng South Street. Give full play to the role of the gateway of Beijing's urban sub-central transportation hub, build a number of comprehensive transportation hubs such as the urban sub-central station, Dongxia Park, Tongma Road, and Universal Studios North, and promote the development of "station city integration". Along the river, along the green, along the road to build continuous through the slow traffic network, to achieve dense road network, node access, good environment of the slow traffic system.

To build an ecological city that integrates water and city and interweaves blue and green. Forming a green spatial pattern of "one belt, one axis, two rings and one heart". Relying on the Grand Canal to create a blue-green interwoven ecological civilization belt that highlights the charm of public space, relying on the Sixth Ring Road to build five parks, including the Sixth Ring Road High Line Park, to create a fresh and bright innovative development axis. Zhangjiawan Park and 13 other parks have been built to close the green leisure and recreation ring around the city. By 2025, the coverage of the 500-meter service radius of the park green space will reach 95%. We will continue to improve the urban water system pattern of "three networks, four zones, multiple water surfaces and multiple wetlands" in the sub-center, strengthen the construction of waterfront ecological zones such as the North Canal and Chaobai River, and implement comprehensive management of river channels such as the Yudai River and the Xiaotaihou River. The "Tongzhou Weir" flood diversion system has been basically completed, the warm tide river reduction project has been implemented, the Songzhuang flood storage Area (Phase II), the Wenyu River and the North Canal have been comprehensively treated, and the main water quality indicators of the key reaches of the North Canal have reached the Class IV standard.

We will comprehensively improve our capacity to secure resources and energy. It has continued to strengthen the supply security of the sub-center, promoted the Beijing urban sub-center water transfer main line project, completed the second phase of the Tongzhou Water Plant Project of the South-to-North Water diversion project, built and renovated the water supply network in the old city, promoted the replacement of self-provided Wells through the inventory management, and kept the safety factor of water supply above 1.3. We will continue to optimize the regional power grid structure, strengthen the power grid emergency support capability, and promote the implementation of the black start-up project of the sub-central Power Operation support center and the regional energy center in the canal core area. Improve the regional natural gas supply pattern of "four stations, five lines, and three unicom", and promote the full coverage of gas pipeline networks in urban areas and the three characteristic towns of Zhangjiawan, Taihu, and Songzhuang. Optimize the heating network layout, innovate green energy application demonstration, and build a multi-energy coupled energy system and a renewable energy integrated heating system for Beijing City sub-central Station. In the administrative office area, cultural tourism area, canal business district and other key areas to build a comprehensive pipeline corridor framework system to support municipal energy security supply.

3. Accelerate the high-quality infrastructure construction of Pingyuan New City

Implement the functional positioning of Pingyuan New City, undertake the appropriate functions and population of the central urban area, improve the level of urban development and comprehensive service capacity, give full play to the role of multi-point support functions, effectively enhance the capacity for sustainable development, and create a convenient and efficient, viable, livable and attractive Pingyuan New city.

Build a transportation system for the new city that connects inside and outside. Strengthen the external public transportation links of Pingyuan New City, promote the construction of urban (suburban) railway and urban rail transit, complete the south extension of the first phase of rail transit Changping Line, accelerate the promotion of rail transit line 19 south extension, north extension and R4 line 1, Line 15 east extension and the overall upgrading of suburban railway line, and create a "half-hour rail transit circle" between the central city and the new city. Vigorously build Huoying (Loess Shop) station and other track micro-centers, create the urban fulcrum of station and city integration, and promote the balanced development of population, industry, housing and services in the new plain city. We will expand the road communication channels between Pingyuan New City and central urban areas, accelerate the implementation of rapid upgrading of Beiqing Road, Anli Road and Jingmi Road, and open up a number of breakpoints such as the west section of Jingliang Road and the south extension of Majiapu West Road. Improve the internal road network structure of the new city and strengthen the connection between functional areas. Improve the level of refined design, construction and management of road traffic, synchronously implement the construction of municipal facilities such as energy and drainage, optimize the spatial functions of roads according to local conditions, guarantee the right of way of slow traffic, and enhance the attractiveness of the slow traffic system.
