Comparative studies on community structure and biodiversity of copepods and rotifers were carried out in four lake areas with different trophic levels (mesotrophic, eutrophic and hypertrophic) in Lake Donghu. The results show that the higher the trophic level of the lake water, the lower the species diversity (measured as species number and biodiversity index) of the copepods and rotifers. The long - term ecological studies in Lake Donghu show that the much more and more serious eutrophication has resulted in a remarkable decline in the biodiversity of the plankton communities.
