| 摘 要： | 于2006年和2007年对东平湖水域2条断面、9个站位的底栖动物进行了3次采样调查,研究了东平湖底栖动物的群落组成和生物多样性;并应用大型底栖动物污染指数(MPI)和生物学污染指数(BPI)对东平湖水域环境质量现状进行了评价。结果表明:已鉴定出底栖动物31种,其中腹足纲10种、瓣鳃纲11种、甲壳纲4种、昆虫纲2种、寡毛纲1种和蛭纲3种。平均栖息密度相对较低,为186.79(±102.35)ind./m2;螺类最多,其次为昆虫类和寡毛类,甲壳类、腹足类和水蛭类所占比例较少。平均生物量为157.72(±188.74)g/m2;腹足类占绝对优势,其次为螺类,昆虫类、寡毛类、甲壳类和水蛭类所占比例较少。随采样时间的推移,底栖动物栖息密度和生物量均逐渐显著降低。底栖动物多样性指数、丰富度指数和均匀度指数均较低。MPI和BPI评价结果表明:东平湖水域环境质量以轻度污染(轻中污染和轻污染)为主,总体处于良好状态。

| Abstract: | In order to understand the biodiversity of macrozoobenthos fauna and environmental quality of Dongping Lake,three times survey was made at 2 sections with 9 sites in 2006 and 2007,with the species composition,biomass,inhabit density,macrozoobenthos pollution index(MPI) value,biological pollution index(BPI) value of macrozoobenthic fauna investigated,and the environmental quality analyzed.A total of 31 macrozoobenthos species were recorded,including 10 species gasteropod,11 species lamellibranch,4 species Cr... |
