The study investigated the benthic community structure, β-diversity and its composition in Lake Ulansuhai, and the effects of environmental/spatial factors on benthic β-diversity were analyzed by the Mantel test. The results showed that the benthic community structure in Lake Ulansuhai had significant seasonal differences, and the variance analysis also showed that there were differences in the biomass and diversity index for zoobenthos. The β-diversity of the benthic community in the Lake Ulansuhai was maintained at a high level and dominated by the turnover component, with the ratio of the turnover component reaching 80%. Mantel's test showed that the geographic distance did not have a significant effect on the β-diversity in the benthic community (P > 0.05). In contrast, environmental factors (mainly total nitrogen) in the water were positively correlated with benthic β-diversity and its turnover component, which indicated that environmental factors were the main drivers affecting the structure of benthic communities in Lake Ulansuhai.
