摘 要：
为了解海河流域滦河水系的生态完整性和底栖动物群落的恢复,2013年5—8月对滦河水系大型底栖无脊椎动物的群落结构特征进行了初步调查,共检测到大型底栖无脊椎动物90种,隶属于7纲11目65属。利用Shannon-Wiener多样性指数、Margalef丰富度指数、Pielou均匀度指数、Simpson多样性指数对滦河水系的水质进行了初步评价,在主成分分析和因子分析的基础上,对23个定量采样点的类型做了聚类分析。结果显示,水生昆虫23种,占26%;甲壳类2种,占2%;环节动物9种,占10%;软体动物10种,占11%;摇蚊幼虫46种,占51%。生物多样性指数表明滦河水系的整体水质为轻度污染,底栖动物的多样性与底质类型关系密切。

摘 要：
In order to understand ecological integrity and recovery of benthic animal community of Luanhe River basin, a preliminary investigation of benthic macroinvertebrate community structure in Luanhe River basin was conducted from May to August in 2013. A total of 90 species, belonging to 65 genera, 11 orders and 7 classes were detected. Biodiversity indices were calculated using Shannon-Wiener diversity index, Margalef abundance index, Pielou evenness index and Simpson diversity index. 23 locations were clustered based on theresults of principal component analysis and factor analysis. The results showed that mosquito larvae species were most abundant, with 46 species accounting for 51% of the overall species, followed by 23 species ofaquatic insects(26%), ten species of mollusks(11%), nine species of annelids(10%) and two species of crustaceans(2%). Biodiversity indices indicated that diversity of benthic macroinvertebrates was closely related to sediment type and the water quality of Luanhe River basin was lightly polluted.
