Abstract：The Zhanghe River,an important river in the Zhangwei South Canal system of the Haihe River Basin,originates from the Shanxi Plateau and flows through Shanxi,Henan,and Hebei provinces,converging with the Wei River at Xuwancang to form the Wei Canal.This article takes the mainstream of the Zhanghe River as the research object,reviews the previous management of the mainstream of the Zhanghe River,and conducts a retrospective evaluation of the river flow,ecological water discharge satisfaction,water environment quality,terrestrial ecological environment,and aquatic ecological environment of the mainstream of the Zhanghe River.The results show that due to the interception and storage of Yuecheng Reservoir,the mainstream of Zhanghe River often experiences flow interruption,the ecological water discharge of the river is not satisfactory,the aquatic organisms are scarce,and coupled with illegal sand mining in history,the ecological environment of the river is poor.Based on the main ecological and environmental issues existing in the mainstream of the Zhanghe River,suggestions for subsequent protection and management have been put forward.
