We will strengthen the upgrading and utilization of renewable energy, new energy and clean energy equipment and facilities and the recycling of waste building materials

By the middle of this century, China will complete the construction of a modern, high-quality national comprehensive three-dimensional transport network, with a world-class transport infrastructure system, an effective balance between transport supply and demand, equal quality services, and strong safety guarantees. New technologies are widely used to achieve digitalization, networking, intellectualization and greening. Travel is safe, convenient and comfortable, logistics is efficient, economic and reliable, to achieve "people enjoy their travel, goods better flow", to fully build a transportation power, to fully build a modern socialist country as a good first.

Third, optimize the national comprehensive three-dimensional transportation layout

(1) Building a sound national comprehensive three-dimensional transportation network

The national comprehensive three-dimensional transportation network connects all administrative regions at and above the county level, border ports, national defense facilities and major scenic spots throughout the country. Guided by overall integration, we will focus on strengthening weak links, reconnecting, improving networks, and improving performance, and pay more attention to optimizing the use of existing resources and improving the quality of incremental supply. We will improve railway, road, water transport, civil aviation, postal and express delivery infrastructure networks, and build a comprehensive national three-dimensional transport network with railways as the main task, roads as the basis, and full play to the comparative advantages of water transport and civil aviation.

By 2035, the total size of the national comprehensive three-dimensional transportation network will be about 700,000 kilometers (excluding overseas sections of international land routes, air and sea routes, and postal routes). Among them, there are about 200,000 kilometers of railways, 460,000 kilometers of highways and 25,000 kilometers of high-grade waterways. There are 27 major coastal ports, 36 major inland ports, about 400 civil transport airports, and about 80 postal and express hubs.

(2) Accelerating the construction of the main framework of an efficient national comprehensive three-dimensional transportation network

The main skeleton of the national comprehensive three-dimensional transportation network is composed of the most critical line network in the national comprehensive three-dimensional transportation network, which is the main artery of China's inter-regional, inter-urban agglomerations, inter-provincial and international transportation, the main axis supporting the development and protection of national space, and the backbone network with the highest resource allocation efficiency and maximum transportation intensity of various transportation modes.

According to the national regional development strategy and the pattern of territorial space development and protection, combined with the characteristics of future transportation development and spatial distribution, the key regions are divided into three categories according to the magnitude of transportation demand. Four regions in the Beijing-Tianjin-Hebei region, the Yangtze River Delta, the Guangdong-Hong Kong-Macao Greater Bay Area and the Chengdu-Chongqing Twin City Economic Circle serve as poles; eight regions in the middle reaches of the Yangtze River, the Shandong Peninsula, the west bank of the Straits, the Central Plains, Kazakhstan, Southern Liaoning, the Beibu Gulf and the Guanzhong Plain serve as clusters; and nine regions in Hubei Yu, Central Guizhou, central Yunnan, central Shanxi, the north slope of the Tianshan Mountains, Lanxi, Ningxia Yanhuang, Lhasa and Kashgar serve as clusters. According to the intensity of the traffic connection among poles, groups and groups, the main skeleton of the national comprehensive three-dimensional traffic network composed of spindles, corridors and passages is built. The length of the backbone of the national comprehensive three-dimensional transportation network is about 290,000 kilometers, including 56,000 kilometers of national high-speed railways and 71,000 kilometers of general speed railways. 61,000 kilometers of national expressways and 72,000 kilometers of ordinary national roads; The national high-grade waterway is 25,000 kilometers.

Speed up the construction of six main axes. We will strengthen links between the four poles of the Beijing-Tianjin-Hebei region, the Yangtze River Delta, the Guangdong-Hong Kong-Macao Greater Bay Area and the Chengdu-Chongqing Twin City economic Circle, and develop a comprehensive, multi-channel, multi-dimensional, large-capacity and fast-moving transportation main axis. Expand the four-pole radiation space and transportation resource allocation capacity, build a key platform for the coordinated development of comprehensive three-dimensional transportation in China and the convergence and transformation of domestic and international transportation, and give full play to the important role of promoting the North-South interaction and east-west integration of regional development in the country.
