Benthic animals molluscs biomass as the highest, with more moderate aerobic benthic organisms exist, and the water body suited Zoobenthos survival.
底栖动物中软体动物的生物量为最高，有较多中等需氧底栖生物存在，水体状况适合底栖动物生存。

The concept and main groups of zoobenthos was summarized, and studies of assessment and monitoring of water quality by using benthic animal in China were reviewed.
The present paper embodies two studies: faunal analysis of aquatic oligochaeta in Zhongshan, South China, and environment gradient analyses of zoobenthos in 13 Yangtze shallow lakes.
