Abstract

The benthic fauna of the Jinan reservoir ecosystem and river ecosystem is dominated by Insecta species, followed by Gastropoda species, and the species of Insecta and Gastropoda are more in rivers than in reservoirs. Judging from the seasonal changes of benthic species in the two ecosystems, both showed a trend of high in spring and low in autumn. Judging from the changes in the density of benthic invertebrate in the water bodies of the two ecosystems, the total density of benthic invertebrate in the water bodies of the reservoir is low, and the monthly density changes are small, the total density of benthic invertebrate in the river ecosystem is higher than that in the reservoir ecosystem, and the density fluctuation is relatively large. The fluctuation range of benthic diversity in the reservoir ecosystem is smaller than that in the river ecosystem.
