摘    要:2010年4月至12月对微山湖水体中浮游动物进行了4次调查,共检出浮游动物77种,其中原生动物18种,轮虫45种,枝角类8种,桡足类6种。夏、秋季浮游动物物种数最多(48种),春、冬季最少(43种)。春季浮游动物丰度最高(1.26×10^3ind.·L^-1),夏季最低(0.47×10^3ind.·L^-1),秋季和冬季分别为0.75×10^3ind.·L^-1和0.71×10^3ind.·L^-1。夏季浮游动物生物量最高(6.69mg·L^-1),冬季最低(1.52mg·L^-1),春季和秋季分别为2.41mg·L^-1和4.03mg·L^-1。浮游动物香农指数变化在1.74~2.15;均匀度指数变化在0.48~0.74。综合评价,微山湖为中营养型水体,应加强对湖区水质保护和合理开发。

Abstract:The community structure of zooplankton was surveyed four times in Weishan Lake from April of 2010 to December of 2010. Totally, 77 species of zooplankton including 18 species of protozoa, 45 species of rotifers, 8 species of cladocera and 6 species of copepods were found, the maximal zooplankton species (48) in summer and autumn and the minimal (43) in spring and winter. There was zooplankton density of0.75×10^3ind.·L^-1 in autumn and 0.71 × 10^3 ind.·L^-1 in winter, the highest density ( 1.26×10^3ind.·L^-1 ) in spring and the lowest (0.47×103ind.·L^-1 ) in summer. The biomass of zooplankton was found 2.41 mg·L^-1 in spring and 4.03 mg·L^-1in autumn, the maximum (6.69mg·L^-1 ) in summer and the minimum ( 1.52mg·L^-1) in winter. The Shannon-Weiner index was varied from 1.74 to 2.15 while the Pielou index was changed from 0.48 to 0.74. The water quality in Weishan Lake was comprehensively e-valuated as moderate pollution.
