Zooplankton diversity and water quality evaluation in East Zhulong River,Zibo
In order to effectively protect the water ecological environment of rivers in Zibo city and improve the water ecological service function to the city,the zooplankton of east Zhulong River in Zibo was investigated in the autumn of 2022.A total of 31 species of zooplankton belonging to 4 categories were collected in this survey,among which the Rotifera were dominant in the species composition,with accounting for 48.39%of the total zooplankton spe-cies,and the number of Cladocera was the smallest,accounting for 9.68%,and the Brachionus calyciflorus,Philo-dina roseola and Nauplius are the dominant species.The average density of zooplankton was 17.50ind./L,and the average biomass was 0.0473mg/L.The mean value of Shannon-Wiener diversity index and Pielou evenness index of zooplankton were 2.213 and 0.818,respectively.The results showed that The composition of zooplankton was miniaturized and the community structure was simplified.The water quality evaluation results basing on biodiversity index show that the water quality of east Zhulong River was in the state of no pollution-light pollution state.It was suggested that the further effective measures should be taken to strengthen the environmental control around east Zhulong River,reduce the discharge of domestic sewage and reduce the interference from human activities.
