| 摘 要： | 为揭示现阶段太泊湖底栖动物群落现状及时空分布,于2013年5月至2014年5月对太泊湖底栖动物进行为期1周年的季度调查。7个采样点共记录底栖动物10属11种,现阶段底栖动物优势种为羽摇蚊幼虫(Chironomus plumosus)、多鳃齿吻沙蚕(Nephtys polybranchia)、霍甫水丝蚓(Limnodrilus hoffmeisteri),占83.53%以上。密度和物种数在四季差异较大,密度高值在春季,为1 019.64 ind/m~2;冬季和秋季为437.5ind/m~2和287.5 ind/m~2;夏季为264.29 ind/m~2。生物量最高为夏季和冬季,为87.53 g/m~2和86.32 g/m~2、秋季和春季低,为47.26 g/m~2和35.41 g/m~2。多样性分析显示各指数绝对值低,采样点间采集到底栖动物数和物种数差异大。研究结果表明太泊湖底栖动物群落结构单一,生物总数四季差异明显,水质营养化严重。

| Abstract: | To describe the status of benthic animal communities and its spatial and temporal distribution in Taibo Lake, we surveyed quarterly the benthic animals in Taibo Lake from May 2013 to May 2014. 11 species of benthic animals belonging to 10 genera were collected in 7 sampling sites. Chironomus plumosus, Nephtys polybranchia and Limnodrilus hoffmeisteri were dominant species in Taibo Lake, accounting for 83.53% of total animal number. Density and species mumber of benthic animals changed significantly with seasons. The highest density of benthic animal appeared in Spring, and it was 1019.64 ind/m2. Winter and Autumn were 437.5 ind/m2 and 287.5 ind/m2, Summer was 264.29 ind/m2. The highest biomass appeared in Winter and Summer with 87.53 g/m2 and 86.32 g/m2. Autumn and Spring were 47.26 g/m2 and 35.41 g/m2.Diversity analysis indicated that some various index absolute values are low.There was significant difference in benthic animal number and species mumber that were collected in 7 sampling sites The results showed that the community structure of benthic animals was simple and the total species had obviously seasonal differences in Taibo Lake. The water eutrophication is serious. |
