摘　　要：文中以辽河干流为研究区,选取干流上游福德店、铁岭水文站,中游马虎山水文站,下游六间房水文站为代表站,采用流量历时曲线法计算河流生态流量,并结合蒸发渗漏需水、河口湿地生态需水计算成果,进行辽河干流生态需水整合。在此基础上,以水文循环过程为主线,按消耗型生态需水及非消耗型生态需水2个类别,对各河段生态需水进行评估整合,求得辽河干流河流生态需水总量,可为辽河生态治理提供参考。In this paper,the Liaohe River Main Stream is taken as the research area,and four representative stations of Fudedian and Tieling hydrological stations in the upper reaches of the main stream,Mahushan hydrological station in the middle reaches,and Liujianfang hydrological station in the lower reaches are selected.The flow duration curve method is used to calculate the river ecological discharge,and the ecological water demand of the Liaohe River main stream is integrated by combining the calculation results of evaporative and seepage water demand and estuarine wetland ecological water demand.On this basis,the hydrological cycle process as the main line,according to two categories of consumptive ecological water demand and non-consumptive ecological water demand,the ecological water demand of each reach was evaluated and integrated,and the total ecological water demand of the Liaohe River Main Stream was obtained.It can provide reference for ecological governance of Liaohe River.
