摘　　要：对国内外河流生态环境需水量的计算方法进行了分析研究，重点分析了各种方法的优缺点及适用条件。并根据南水北调西线一期工程调水河流近40年的年月径流实测资料，分别采用7Q10改进法、最小月平均流量法、Tennant法计算了5条河流的最小河流生态环境需水量。计算结果表明，生态环境需水占径流量的10％～15％，河流基流量方法计算河道生态环境需水量符合实际情况，比较适于中国河流应用。the calculation method of water demand of domestic and foreign river ecosystem environment was analyzed and studied. We focused on the advantages and disadvantages of various methods and its applicable conditions. Based on the 40 year-month runoff measured data of first stage on the western route, 7Q10 Improving methods, minimum flow method and tennant method were adopted separately to calculate the mini- mum monthly average water demand of river ecosystem of five rivers. The results showed that eco-environmental water demand occupy for 10 ~/00 to 15 ~//0 of runoff, river ecological water demand accords for the actual conditions through the calculation of river base flow methods, which is the most suitable method for the application of China＇s rivers.
