This article uses the system concept to analyze the systematic attributes of river systems,including hydrological attributes that follow natural laws,resource functional attributes that serve the economy and society,and ecological attributes that provide a living environment for aquatic organisms.The interaction and influence of river system,human society and ecological environment brought by these three attributes are analyzed,and the importance of system thinking to reservoir dam safety and comprehensive benefits is pointed out.This article discusses that the scientific evaluation of the quality of the river ecosystem cannot rely on a single index for evaluation,but a complete evaluation system should be used to scientifically evaluate the quality of the river ecosystem.This article puts forward the opinions and suggestions on the river ecological environment evaluation indicators that the dam industry should focus on,and emphasizes the new legal responsibilities of the dam industry in the protection and restoration of the Yangtze River′s ecological environment stipulated by the Yangtze River Protection Law.
