摘要
本文对雅砻江锦屏二级减水河段,依据国外提出的Tennent法、R2-Cross法中对水力生境参数描述,以及相关冷水鱼大西洋鲑和褐鳟产卵期对水力生境参数的报导,结合该河段鱼类生境的具体情况,对目标鱼类的水力生境需求问题进行了探讨。确定了河段鱼类生境需求的流速、水深、水面宽、湿周、水温等水力参数。为确定鱼类生境需求的水力参数进行了探索性的工作。
The water of river reach from the dam to tail water with length of llgkm in No.2 Power Station of Jinping Hydro Project will be reduced due to diversion of power station. The hydraulic parameters of habitat requirement for the existence and growth of fishes in this river reach are investigated. The parameters are determined according to the Tennent method and R2-Cross method and referring to the demand of spawning Atlantic salmon and brown trout. The required flow velocity, average water depth, fiver width, hydraulic perimeter and cross section area of flow are suggested.
