Abstract:

Water resources in China are unevenly distributed in time and space, which mismatches with China's economic and social patterns. The water situations severely restrict China's sustainable development. There are many problems in the present river and lake systems in China, mainly including frequent occurrences of flood and waterlogging, water shortage, river and lake shrinkage, severe water pollution, and water ecology and environment degeneration. It is one of the key subjects to protect water resources in China's economic and social developments. China's water conservancy development strategy is to actively propel the establishment of the interconnected river system network (IRSN), improve the ability of water resources allocation, guarantee river and lake health, and control floods and droughts. It is of significance to conduct research on the theories and techniques of IRSN. This paper mainly analyzed the situation of water resources that faces China, and then discussed the necessity and urgency of IRSN, proposed the key scientific issues of IRSN, and prospected the research framework for solving the relevant issues.
