| 摘 要： | 分别于2009年8月和2010年5月对太湖流域37个采样点的大型底栖动物进行调查采样.共采集到大型底栖动物69种,其中寡毛类15种,占21.7％；软体动物16种,占23.2％；甲壳动物5种,占7.2％；水生昆虫27种,占39.1％；多毛类6种,占8.7％.利用大型底栖动物的物种组成以及物种相对丰度,应用双向指示种(TWINSPAN)和无偏对应分析(DCA)将37个采样点分为4组,第1组的指示种为齿吻沙蚕和河蚬等多毛类及软体动物；第2组的指示种为太湖大螯蜚和方格短沟蜷等多毛类及软体动物；第3组的指示种为霍甫水丝蚓等环节动物；第4组的指示种为正颤蚓和摇蚊幼虫.典范对应分析(CCA)结果表明:电导率和总氮是影响底栖动物分布的主要环境因子,铵氮、CODcr、透明度、叶绿素a、水深及硝态氮对底栖动物分布也有影响.

| Abstract: | An investigation was conducted on the macrobenthos at 37 sampling sites in the Taihu River basin in August 2009 and May 2010.A total of 69 macrobenthos species were collected,of which,15 species(21.7% of the total) were oligochaetas,16 species(23.2%) were mollusks,5 species(7.2%) were crustaceans,27 species(39.1%) were aquatic insects,and 6 species(8.7%) were polychaetes.Based on the species composition and relative abundance,and by using two-way indicators species analysis(TWINSPAN) and detrended correspon... |
