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
Reported the fish populations and their relative numbers in the river reach of several hydropower stations in Sichuan Province, of which the number of fish in the dehydrated section of the power station and the tailrace section of the power station reservoir area is scarce and has no fishery significance; and the reservoir area or the tailrace area Compared with the natural river channel, the number of fish species is rather rich, which has some fishery significance.We also compared the natural rivers with a length of about 15km between Ganpu and Li County water diversion power plants in the upper reaches of the Minjiang River, However, the number of fish species in the dehydrated reach is significantly reduced; however, the number of fish species in the river reach of the reservoir area and the tailrace is still relatively abundant. Designing a cascade hydropower station should take the form of development of the Ganpu and Lixian Power Stations to protect Water environment, aquatic organisms and fish diversity, less affected
