摘　　要：分析了水文学法、水力学法和栖息地法计算河道生态需水量的原理及适用性,以姜射坝水电站减水段为例,分别应用Tennant法、R2-Cross法和PHABSIM模型计算了重口裂腹鱼产卵期生境需水量,并进行了对比分析。建议当河流水生生态敏感程度较高时采用栖息地法来计算河段需水量,以期最大程度地保护关键生境条件,为实现水电开发与生态环境协调发展提供技术支持。The principles and applicability of hydrology method, hydraulic method and habitat method in calculating raver ecological water requirement are analyzed herein. The Tennant method, R2-Cross method and PHABSIM model are used to ascertain the habitat water demand during Schizothorax David I spawning period in the decrease water section of Jiangsheba Hydropower Station. By comparing three calculation results, the habitat method （PHABSIM） is recommended for calculating river ecological water requirement when the aquatic ecological sensitive degree of river is higher. The habitat method can provides technical support to realize the harmonious development between hydropower and ecologic environment.
