Abstract:

China's water resources shows an uneven distribution pattern of shortage in the north and abundance in the south, and the trans-basin water diversion is an effective solution to alleviate the uneven distribution. The South-to-North Water Diversion Project (SNWD) is an important strategic infrastructure to alleviate the shortage of water resources in the northern China, optimize the allocation of water resources, and improve the ecological environment. The planning and construction of the SNWD lasted more than 70 years from the initial proposal of the scheme concept to the completion of the first phase of the project. Key issues, such as optimal allocation of water resources, impact on the ecological environment, and project construction management mechanism have been studied deeply, and a series of key results have been applied to the preliminary demonstration of the SNWD, and to help high-quality planning and construction of the SNWD. In 2014, the first phase of the SNWD was officially opened, marking that the project had changed from a grand concept to a great project, and entered the stage of engineering practice from scientific research. For the 9 years since the project opened, the comprehensive benefits of the project have been continuously demonstrated. This paper comprehensively sorts out the series of scientific research results on several key issues of the high-quality development of the SNWD. Then the practical results of the SNWD in optimizing the water resource allocation pattern, improving the water safety guarantee capacity of the water receiving area, and promoting the protection and restoration of the ecological environment along the routes were systematically summarized. Finally, we put forward the thinking and prospect of the follow-up construction and operation of the project.
