| 摘 要： | 2012年9月对太子河流域39个采样点的鱼类群落结构和环境因子特征进行野外调查,并运用香农威纳指数、均匀度指数和典范对应分析等方法分析鱼类的群落结构。结果表明;共采集到7目35种鱼类,鲤形目为优势种类,各采样点鱼类个体数量平均值为164.97尾,香农维纳指数平均值为2.56,均匀度指数平均值为0.82,物种丰富度指数平均值为1.38。典范对应分析表明:影响鱼类群落的主要环境因子是总氮、河宽和溶解氧,太子河流域受到了一定程度的干扰。

| Abstract: | The com m unity structure and spatialand tem poraldistribution of fish w ere surveyed in 39 collecting sites in TaiziR iver B asin in Septem berof2012 to show the relationship betw een the com m unity structure offish and the associated environm entalfactors by Shannon-W einerIndex,Pielou Index,M argalefIndex and C anonicalcorrespondence analysis.There w ere 35 fish species in Taizi R iver B asin,w ith average fish density of 164.97 fish per sam pling site, Shannon-W iener Index of 2.56 and Pielou Index of 0.82. C anonicalcorrespondence analysis revealed thatfish com m unity structure w as heavily determ ined by TN,river w idth and dissolved oxygen level(DO),indicating thatthe w aterin Jinan R iverw asfound to be polluted. |
