According to water quality pollution level of Huadi River in Guanazhou,we analyzed the status of SD,chlorophyll a,phytoplankton and zoobenthos in the waterbody.The results indicated that the dominant phytoplankton were cyanophytes which were contaminative-resistant habit and proliferated in the waters.The density of Limnodrilus sp.contaminative-resistant of zoobenthos increased yearly,and the concentration of TP and TN also increased year after year.Besides,the pollution resulted from organic matter became more serious.The self-purification capacity of Huadi River can't treat the pollution by itself,so related government departments should attach importance to integrated environmental control.This paper pertinently advised that we should take effective measures which combine ecological theories and multi-side co-operation to control the pollution in Huadi River.
