摘要：
The national water network project is a major strategic deployment in the 14th Five-Year Plan (2021-2025) and the Outline of the 2035 Vision Goals. However, under the influence of global changes, it is facing new opportunities and challenges. Based on the analysis of the background of climate, geography and economic and social development and the characteristics of unbalanced distribution of soil and water resources, this paper has completed three research works. It studies the relationship between supply and demand of water resources in the changing environment. Then it analyzes the planning and layout of the national water network and the effectiveness of the typical water network. Finally, some problems and countermeasures in the planning and construction of the national water network are discussed. Research shows that the impact of global change is more and more prominent. As the country enters the stage of high-quality development, people have higher requirements on the quality and guarantee of water supply. Moreover, the construction of national and regional water networks is an important measure to cope with the impact of environmental change and improve national water security. The construction of the national water network can significantly improve the guarantee of water supply and irrigation, flood control and drainage capacity, and enhance the quality of natural river and lake water environment, but it still has room for optimization and improvement. We need to coordinate regional "water-soil-air-gas" and "man-land" relations, strengthen scientific and technological innovation in the construction of the national water network, improve the comprehensive benefits of ecological environment and economic development of the project, and support the construction of national ecological civilization and high-quality development. © 2023 Science Press.
