摘　　要：主要从保护河流水生生物栖息地出发,探讨山区河流生态需水量问题。文章运用Tennant法、湿周法和以河流上游某断面50%保证率的年平均流量的30%计算方法,对湖北省神农架林区长坊二级水库电站工程坝址下游最小生态需水量,进行计算、比较分析,提出其最小生态需水量为0.22m3/s,为该水电站工程环境影响评价及科学运行提供依据。On the premise of protecting fiver hydrobiology habitat, ecological water demand in mountainous rivers was studied. Taking Changfang No.2 Reservoir Hydropower Station project in Shennongjia Forest Region, Hubei Province for instance, minimum ecological water demand in lower reach of the dam was calculated and analyzed, which will offer reference for environment impact assessment and scientific operation of the proposed project.
