Abstract
In order to discuss the influence of Langtianshui Hydropower Station on river ecology,taking river health assessment as an example,the changes of the ecological flow satisfaction,benthic invertebrate species and fish species in the upstream and downstream of the hydropower station were investigated.This is mainly due to the blocking effect of the hydropower stations on the river,which makes the river sections between the hydropower stations form a relatively stable ecosystem.The purpose of this study is to analyze the reasons why the hydropower stations in small and medium-sized rivers have little impact on the river ecology after completion,and to provide a theoretical basis for the construction planning of hydropower stations.关键词
