摘要：
In order to explore the influence of the water system connectivity on the development and utilization of water resources in the Three Outlets Basin of Southern Jingjiang River, the evolution of water level and the variation characteristics of runoff in the years of 1965—2017 were analyzed by the method of Mann-Kendall trend test. This paper focuses on the analysis of the influence of the water system connectivity on the water resources quantity, hydrological drought and the development and utilization of different river systems in the Three Outlets Basin of Southern Jingjiang River. The results show that: The characteristic water levels of the Three Outlets Basin of Southern Jingjiang River changed significantly. and the average annual water level has decreased, which is not conducive to the development of water resources. The variation range of average annual runoff of the Three Outlets Basin of Southern Jingjiang River is large, and the development and utilization of water resources are more difficult. The number of hydrological droughts in the Three Outlets Basin of Southern Jingjiang River system showed an increasing trend, and the drought duration is increasing. The problem of water shortage is severe. The regional distribution of annual runoff in the Three Outlets Basin of Southern Jingjiang River is not balanced and the annual variation is large, which is very disadvantageous to the development and utilization of water resources in the basin. © 2021, Editorial Board of Water Resources Protection.
