四川几个水电站影响区的鱼类

报道了四川境内几个水电站影响区河段的鱼类种群及其相对数量。其中电站脱水河段、电站库区尾水区河段鱼类数量稀少，已无渔业意义；库区或尾水区与天然河道相连区河段，鱼类种类数量较丰富，有一定渔业意义。还比较了岷江上游支流杂谷脑河的甘堡、理县引水式电站间留有长约15km左右的天然河道，其脱水河段鱼类显著减少；但库区及尾水区与天然河道相连的区河段鱼类种类数量仍较丰富。设计修建梯级水电站应采取甘堡、理县电站的开发形式，能保护水域环境、水生生物和鱼类多样性，少受影响。

Fishes in Various Sections of Rivers of Some Water Power Stations in the Sichuan Province

The paper is about the initial finding of fishes in various sections of rivers of some water power stations in the Sichuan Province. There are few fishes in man-made dried sections and the tails of rivers of the power stations, but there are lots of fishes in the station sections, station water tails and sections connected with natural rivers. The writer has also compared the fishes in different sections of the Ganbao and Lixian Water Power Stations on the branch, the Zagunao River, of the Minjiang River and proposed that the design and building of the two stations should be adopted as a model.
