Abstract: 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 the results 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 of aquatic 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.
