A survey of macrozoobenthos in and aquatic physicochemical properties of the Huangpu River was conducted in an attempt to explore community structure of the macrozoobenthos and its relationship with environmental factors. Samples of macrozoobenthos and deposits were collected at 11 sampling sections along the Huangpu River and its upstream tributaries in November 2013 and July 2014. A total of 29 species of macrozoobenthos were harvested and identified to be 14 Annelid species, 10 Arthropoda species and 5 Mollusca species. Among them, Limnodrilus hoffmeisteri,Limnodrilus grandisetosus,Corbicula fluminea and Corbicula nitens were dominant species. The macrozoobenthos in the river system was 3 646.4 m-2 in average density, with Annelida being the highest, reaching 3 575.6 m-2, and 16.74 g·m-2 in average biomass with Arthropoda being the highest, reaching 9.35 g·m-2. Annelida was mainly distributed in the middle and lower reaches of the Huangpu River, while Mollusca and Arthropoda were in the upstream and upstream tributaries of the Huangpu River. Correlation analysis indicates that CODMn, TN and TP were the main environmental factors affecting distribution of the macrozoobenthos in the Huangpu River.
