介绍了湄公河渔业资源概况及其流域下游主要的洄游鱼类,分析了萨拉康水电站阻隔对洄游鱼类造成的影响,确定了上游湄公河洄游系统的主要过鱼对象;根据萨拉康水电站枢纽布置以及所在地的地形地质特征,对可行的鱼道布置方案进行了优选论证,并对右岸方案鱼道进口、鱼道出口、鱼道结构、附属设施等进行了初步设计探讨。

This paper introduced the general situation of fishery resource in the Mekong River and the main migratory fishes in its downstream.It also analyzed the effect of separation in Sanakham hydropower station on migratory fishes and determined the main fish pass objects in migratory system in the upper Mekong River.According to the layout and the geological and geomorphologic features in Sanakham hydropower station,the feasible fishway layout scheme was selected and proofed,and the fishway entrance,fishway exit,fishway structure and subsidiary facilities in the right bank scheme were preliminary designed and discussed.
