The study investigated the species composition,community structure and species diversity of zooplankton in the eastern zone of Lake Chaohu and analyzed the water quality and the type of nourishment from June 2005 to June 2006.And one hundred and fifty-three species of zooplankton were found,of which fifty-nine species were Protozoa(38.56%),forty-eight species were Rotifera(31.37%),twenty-six species were Cladocera(16.99%),twenty species were Copepoda(13.07%).The Margralaf Index showed that the species diversity was very low during the study period and the species diversity was varied with the season.The results from the analysis of saprobic system showed that from June in 2005 to June in 2006 the eastern zone of Lake Chaohu was in the state of β-mesosaprobic zone.By using the quantity of zooplankton as the biology quantity index of nourishing degree in lakes,the eastern zone of Lake Chaohu was in the state of eutrophication from June to September in 2005 and from March to June in 2006.
