| 摘 要： | 为了解淀山湖大型底栖动物群落结构特征及其与环境因子的关系,于2014-2015年对淀山湖11个采样点的大型底栖动物按季度进行8次调查,同时对12项水环境指标进行监测。结果表明,大型底栖动物共计47种,其中寡毛类4种(9%),多毛类4种(9%),甲壳类6种(13%),摇蚊幼虫18种(38%),软体动物12种(26%),其他3种。河蚬Corbicula fluminea为第一优势种(IRI=41.26),其次为疣吻沙蚕Tylorrhynchus heterochaetus(5.23)、红裸须摇蚊Propsilocerus akamusi(3.17)、霍甫水丝蚓Limnodrilus hoffmeisteri(2.37)、日本旋卷蜾蠃蜚Corophium volutator(2.1)、寡鳃齿吻沙蚕Nephtys oligobranchia(1.92)、三角石缨虫Laonome triangularis(1.92)、太湖裸须摇蚊Propsilocerus taihuensis(1.43)。底栖动物密度存在显著的空间差异和季节变化,空间上,其最高值主要集中在湖心区,平均密度为385个/m~2,湖口区次之,为343.2个/m~2,湖湾区平均密度最小,为252.3个/m~2;大型底栖动物的密度在冬季最大,秋季最小,冬季出现大量的红裸须摇蚊。全年与四季的底栖动物密度和水质数据冗余分析(RDA)以及经蒙特卡罗置换检验(Monte Carlo)表明,淀山湖水体的电导率(SPC)、水温(WT)、总氮(TN)、高锰酸钾指数(COD_(Mn))和溶解氧(DO)是影响底栖动物群落分布关键的环境因子。
