Abstract：In order to explore the differences in zoobenthos community structures between the upper and lower lakes of Nansi Lake, the largest freshwater lake in Shandong Province, and their driving factors, the seasonal changes and impacts of environmental conditions on zoobenthos community structures were analyzed based on the benthos and environmental survey data from May (spring) and September (autumn) 2025 by conventional community structure analysis and multivariate statistical analysis methods. The results showed that arthropods were found to be most abundant in the upper lake, while annelids dominated in the lower lake in the spring; in autumn, however, species richness was shown to be declined in the upper lake and increased in the lower lake, with a higher proportion of mollusks. The generally higher abundance was observed in the lower lake than that in the upper lake where the biomass was higher during spring and higher in the lower lake during autumn. There was higher community diversity in the upper lake during spring, while the higher diversity was found in the lower lake in autumn. Two-way ANOVA indicated that the interaction between season and lake zone led to significant effect on biomass, Shannon-Wiener's diversity index (H'), and evenness index (J'). There were higher species richness, Shannon-Wiener's diversity index, and evenness index in the upper lake than those in the lower lake in spring, without significant difference. In autumn, however, there were higher species richness, Shannon-Wiener's diversity index, and evenness index in the lower lake than those in the upper lake, with significant differences in the Shannon-Wiener's diversity index and evenness index (P<0.05). SIMPER analysis showed that, in spring, Richerius marqueti, Stenothyra glabra, and Dicrotendipes lobifer contributed the most to the community structure differences between the upper and lower lakes; in autumn, Nodularia douglasiae, Paracercion sp., and Gabbia fuchsiana made larger contributions. Redundancy analysis (RDA) indicated that the factor significantly affecting species distribution was of transparency in the upper lake in spring, and of dominant role of dissolved oxygen in the lower lake in autumn. The transparency was found to be a key factor for species distribution in the lower lake. The finding provides scientific evidence with future regional ecological management and conservation.
