Study on the estimation of ecological basedischarge in Tashisai River
Ecological basedischarge,as the key to the stability of river ecosystems and the protection of biodiversity,plays a crucial role in maintaining the function and structure of river ecological environment.This study takes the Tashisai River as a case study to analyze and calculate the ecological basedischarge in depth,aiming to provide a scientific basis for ensu-ring the ecological stability of the river and meeting the ecological water demand.Based on years of measured natural runoff data,this study comprehensively evaluates the ecological basedischarge of the Tashisai River diversion hub section using va-rious methods such as the Tennant method,the average annual flow rate of the driest month,the Qp method,and the wet perimeter method.The research results show that:(1)During non flood season,the ecological basedischarge of Tashisai River is 0.202 m3/s,while during flood season it is 1.21 m3/s;(2)By comparing and evaluating the calculation results of various methods,the river section can meet the ecological basedischarge standards throughout the year;(3)The actual run-off generally exceeds the ecological basedischarge standard,with an ecological basedischarge satisfaction rate of over 0.9 and a compliance rate of over 80％,indicating a high degree of ecological basedischarge satisfaction for the Tashisai River under current management and natural conditions.These results provide important scientific basis for the ecological protec-tion and water resource management of Tashisai River and similar rivers.
