| 摘 要： | 为研究梯级电站修建及运行不同阶段导致的河流生境变化对鱼类群落结构和生态类型的影响，本研究于2005-2017年间在乌江下游银盘电站坝上坝下江段开展了蓄水前（2005、2008-2009年）、蓄水后两年内（2011-2012）蓄水6年后（2017年）共6个年度鱼类资源监测，采用多样性指数和多元统计方法分析了该江段鱼类种类组成、群落结构特征及其变化。6年共监测到鱼类93种，鱼类种类数随蓄水进行呈现先降低后升高的趋势。受生境变化影响，鱼类优势物种发生变化，电站蓄水前后差异较大，特别是蓄水后两年内差异尤其显著。蓄水前后鱼类群落结构也发生了变化，在61.79%的Bray-Curtis相似性水平上，蓄水前鱼类聚为一组，蓄水后两年内鱼类聚为一组，2017年单独一组，在0.05水平上差异显著。总体上看，生态类型组成上以缓流型、底层、定居性、杂食性和产粘性卵鱼类占优；蓄水后两年内中上层鱼类和静水型鱼类个体数占比显著增大。
