Abstract：The reservoir in the Yellow River Diversion Plain in Binzhou City is an important drinking water source,and the rate of total nitrogen exceeding the standard has remained high for many years.The phosphorus-containing substances in the Yellow River diversion water are rich and absorbed in sediment,and the total phosphorus content in the overlying water of the reservoir is low,which effectively curbed the eutrophication process of the reservoir to some extent.However,in recent years,there have been a large number of regional algae blooms in reservoirs in summer.Through the analogy analysis of similar reservoirs in the province,this paper concludes that there are ecological risks such as accelerated eutrophication,abnormal algae reproduction and unhealthy development of water ecosystem in severe siltation,low water level operation and hot summer,which further affect the water supply quality and should be paid great attention to.
