摘要
It is shown that the eutrophication of lakes and reservoirs has been very serious in China according to the data of recent years,and the level of eutrophication is deteriorating,which affects the fuictions of water body seriously,decreases the use value,destroys the ecological balance,and endangers human health.The formation causes of eutrophication are analyzed based on the influencing factors,such as nutrient,dissolved oxygen,temperature,light,hydrodynamics and bottom mud etc.,respectively.In accordance with the restoration objectives of water body eutrophication,the aquatic plant remediation techniques,the microorganism remediation techniques and the aquatic animal remediation techniques are discussed in detail.Their treatment mechanism,process characteristics,existing problems and the solving measures are put forward.
