【摘要】：金沙江乌东德水电站的建设对河段水文情势及水环境产生了较大影响,从而改变了当地的鱼类生境。为了探讨电站建成后大坝上下游鱼类生境的变化以及鱼类新的分布格局,在收集河段鱼类资料的基础上,对当地的鱼类资源和鱼类适宜的生存条件进行了分析。结果表明:乌东德水库建成后,大坝的阻隔效应将使鱼类生境片段化和破碎化,下游白鹤滩库区适宜流水生境的鱼类将大幅减少,其适宜环境将集中在白鹤滩库尾不受回水影响河段和部分支流河段,同时,适应缓流、静水开阔水域生活的鱼类将大幅增加,并成为库区的优势种。研究结果将有助于乌东德水电站建成后相关水域的鱼类保护。
[Abstract]:The construction of the Wudongde Hydropower Station on the Jinsha River has a great impact on the hydrological situation and the water environment of the reach. Therefore, the local fish habitat has been changed. In order to study the change of fish habitat and the new distribution pattern of fish in the upper and lower reaches of the dam after the construction of the power station, the fish data of the river reach are collected. The local fish resources and the suitable living conditions of the fish were analyzed. The results show that the barrier effect of the dam will make the fish habitat fragmentation and fragmentation after the construction of the Wudongde Reservoir. The fish suitable for income habitat in the Baihetan reservoir area will be reduced greatly, and the suitable environment will be concentrated in the backwater unaffected reach and some tributaries of the Baihetan reservoir, at the same time, it can adapt to the slow flow. The fish living in the open area of still water will greatly increase and become the dominant species in the reservoir area. The research results will be helpful to the protection of fish in the relevant waters after the completion of the Udongde Hydropower Station.
