Description
Summary:zooplankton played an important role in freshwater ecosystem. Its distribution was influenced not only by biological factors such as fish and aquatic plants, but also by physical and chemical factors such as water temperature, chlorophyll and pH. By analyzing the relationship between zooplankton and physical and chemical factors in urban lakes of Lingnan, the results showed that water temperature was one of the important factors affecting the distribution of zooplankton which had half of the species and dominant species being tropical or subtropical. The abundance of zooplankton was positively correlated with the chlorophyll content in the water, positively correlated with the suspended matter content, and negatively correlated with the transparency and pH. The study was helpful in providing support for the ecological restoration of tropical shallow water urban lakes.
