| 摘 要： | 2007年8月至2008年4月,在湖北省三道河水库6个采样点调查底栖动物,共采集到底栖动物17种,其中水生昆虫11种,均为摇蚊科;寡毛类6种,均为颤蚓科,春季优势种为前突摇蚊,夏季优势种为小摇蚊、流水长跗摇蚊和前突摇蚊,秋、冬季优势种为霍甫水丝蚓,底柄动物种类数、密度和生物量随季节变化明显,种类数夏季＞冬季＞秋季＞春季,密度和生物量春季＞冬季＞秋季＞夏季,周年密度和生物量分别为366.42±102.93ind/m2和0.5649±0.1779g/m2,属贫营养型水库,现存量自坝前向库尾逐步递增,Shannon-Wiener指数、Margalef丰富度指数和Pielou均匀度指数均在夏季最高,秋季最低,4次调查中寡毛类密度均未超过1 000ind./m2,水质属轻度污染.

| Abstract: | During the investigation from August 2007 to April 2008, a total of 17 species of macrozoobenthos were recorded at 6 sampling stations in Sandaohe Reservoir, Hubei Province, including 11 Chironomidae and 6 Tubificidae Oligochaetes. Procladius sp. was the dominant specie in spring while Microchironomus sp., Rheotanytarsus sp. and Procladius sp. were the dominant in summer. In autumn and winter Limnodrilus hoffmeisteri was the dominant. The species number, the density and biomass changed obviously with season... |
