Abstract: Community structure characteristics of zooplankton and water quality were investigated in Chaobai River system including in 3 rivers, 7 reservoirs and 1 lake in Beijing in June and September 2016. The results showed that 98 species of zooplankton were found in the Chaobai River system in June and 131 species of zooplankton in September. The species composition of zooplankton was dominated by protozoa and rotifers. In June, there was average density of zooplankton at 4415.3 ind./L, with average biomass of 1.88 mg/L, and the average Shannon-Wiener diversity index of 2.76. In September, the average density of zooplankton was found at 2977.4 ind./L, with average biomass of 2.09 mg/L, and the diversity index of 3.15. The zooplankton diversity index and comprehensive nutrient status index evealed that the water quality was in the medium eutrophication state in Chaobai River in June 2016, with slight eutrophication in September 2016. Canonical correspondence analysis (CCA) showed that contents of Chl-a, and level and transparency(SD) and water temperature were the main environmental factors affecting zooplankton community structure in Chaobai River in September. The findings indicated that the water quality of Chaobai River in Beijing was in the medium eutrophication state, with dominant species zooplankton of protozoa and rotifers, the main environmental factors of Chl-a and water temperature, which will provide some scientific basis and basic data for the protection and ecological restoration of the ecological environment in the Chaobai River system and the evaluation of ecological service values in the future.
