摘    要:2009年夏季和冬季对龙滩水库浮游动物进行了2次调查,共检出浮游动物73属、137种;夏季为100种,冬季为108种;夏季优势种10种,冬季优势种11种,两季共有的优势种为6种。浮游动物平均密度为5 800个/L,原生动物占绝对优势;平均生物量为1.2366 mg/L,轮虫所占比重最大。两季浮游动物现存量无明显差异,但在水平分布上差异显著。依据浮游动物密度聚类分析,龙滩水库各断面浮游动物分为3大类群。龙滩水库成库后,库尾段浮游动物现存量变化较小,坝前、库中明显增加。依据浮游动物生态学指标评价,龙滩水库水质为贫-中营养型。

关 键 词:龙滩水库  浮游动物  群落结构

Abstract:In summer and winter of 2009, 137 species of 73 genera zooplanktons have been observed in Longtan Reservoir. It is 100 species in summer with 10 dominant species and 108 species in winter with 11 dominant species; and 6 dominant species are observed both in summer and winter. The mean density of zooplanktons is 5800ind./L, protozoa dominating; average biomass is 1.2366mg/L with rotifers amounting to the most part. Zooplankton standing crop in summer and winter is with no significant difference, while the horizontal distributions both in summer and winter are with significant differences. From the density-based clustering analysis on them, zooplanktons in sections of Longtan Reservoir are classified into 3 groups. Since the reservoir was constructed, zooplankton standing crop in the flowing sections at the tail of the reservoir has changed slightly, while significant increases have taken place in the head and middle of the reservoir. According to ecological indicators for zooplankton, the water quality of Logntan Reservoir belongs to mesotrophic-oligotrophic type.
Keywords:Longtan Reservoir  Zooplankton  Community structure
