摘  要：
河流生态需水量是维持河流生物生命周期所需要的水量,对维护河流生态系统稳定和健康具有重要的意义。基于河流水文学原理,采用Tennant法、月保证率法和最小月径流法,对鄱阳湖流域河流[赣江、抚河、信江、饶河(昌江、安乐江)、修河(潦河、修水)]的生态需水量进行了初步分析。根据3种方法计算的结果,取平均值作为鄱阳湖流域河流的生态需水量。结果表明,4-9月河流生态需水量为16.93亿m3/月,10-3月为12.81亿m3/月,分别占流域河流年径流量的10.92%和4.13%,全年生态需水量占流域河流多年平均径流量的15.05%。

摘  要：
The ecological water demand of river is needed to maintain the biological life cycle in river,it is vital important to keep the ecosystem stability and health of river.Based on principles of river hydrology,using the Tennant method,the monthly guaranteeing rate method and the minimum monthly runoff method,the ecological water demands of the rivers of the Poyang Lake basin,including Ganjiang river,Fuhe river,Xinjiang river,Raohe river(Changjiang river,Anlejiang rive),Xiu River(Liaohe river,Xiushui river)) are preliminarily analyzed.According to the calculation results of three methods,the average value is taken as the ecological water demand of Poyang Lake basin.The result shows that river ecological water demand is the 16.93 ×108 m3/month in 4-9 month,12.81×108 m3/month in 10-3 month,accounting for total runoff in 10.92% and 4.13% respectively.The annual ecological water demand of rivers accounts for 15.05% of total multi-year average runoff.
