In order to understand the water ecological environment and the characteristics of plankton community structure in the Zibo area, a survey and study of plankton was conducted in the Zibo Basin in the autumn of 2022. By collecting zooplankton from nine major rivers within the country, a total of 122 species were collected from four phyla. Among them, rotifers are the most abundant, with a total of 77 species, accounting for 63%; Next are protozoa, with a total of 24 species, accounting for 20%; There are a total of 11 species of cladocerans, accounting for 9%; There are 10 species of copepods, accounting for 8%. The average density is 229.58/L, and the average biomass of zooplankton is 2.1997mg/L. The Shannon Wiener diversity index for zooplankton is 3.35. The survey results show that the water quality in the Zibo section is generally in a light pollution state. It is recommended to take further effective measures to strengthen the environmental governance around the watershed, reduce the discharge of domestic sewage, and reduce human activity interference.
