| 摘 要： | 于2008年5月至2009年4月,在太湖北部湖湾-五里湖设置10个监测站点,对该湖的鱼类群落结构进行了调查,采用生物多样性指数对该湖鱼类生物多样性的时空变化进行了分析,并分析了五里湖鱼类资源的种类组成、优势种以及物种多样性水平。结果表明：调查期间,达氏鲌Erythroculter dabryi dabryi和湖鲚Coilia ectenes taihuensis为各个监测站点的绝对优势种;各个站点鱼类群落的Shannon-Wiener多样性指数（H′）介于1.759～3.011,据此判定五里湖鱼类资源群落的多样性和丰富度尚处于相对正常水平。各个监测站点间的鱼类群落结构差异不大,即五里湖的鱼类空间分布比较均匀。渔父岛与鹿丁山以及渔父岛与水上明月间多样性指数在夏、秋季节间以及春、秋季节间差异均显著（P〈0.05）。

| Abstract: | The species composition of fish resources,dominant species and biodiversity were analyzed in Wulihu Lake by investigation of fish community structure and the biodiversity index of species of fish resources at 10 sampling stations in the lake from May 2008 to April 2009.Statistically,Erythroculter dabryi dabryi and estuarine tapertail anchovy Coilia ectenes taihuensis were the dominant species at each sampling station.The biodiversity was ranged from 1.759 to 3.011 at each sampling station,indicating that th... |
