中文摘要：

最小下泄流量的确定是环境影响评价工作的重点,以金沙水电站为例,采用生态水力学法,在综合评判河段水深、流速、水面宽、湿周率、过水断面面积等水力参数以及水力形态要素的基础上,确定金沙水电站最小下泄流量,以满足下游河道鱼类生产繁衍的必要条件。

英文摘要：

Determination of minimum discharge is the focus of the environmental impact assessment. In the case of Jinsha Hydro-electric Power Station, based on the comprehensive evaluation of the hydraulic shape elements and Hydraulics factors such as water depth, flow velocity, flow width, wetted perimeter frequency and flow area, this paper determined the minimum discharge at the Jinsha Hydroelectric Power Station by using eco-hydraulics method to meet the necessary conditions of fish breeding production in downstream river.
