Through the design of AGP-test equipments and methods which could simulate the impact of input of exogenous nutrients on eutrophication, the evolution of algae and aquatic species extinction process in Miyun Reservoir under different environmental and nutritional conditions are simulated. Then the ratio growth rate in the three simulation stages are simulated and analyzed combining the numerical analysis software MATLAB 7.0. At last, the conclusion that in the three designed stage, the total phosphorus threshold which leads to a water bloom in Miyun is respctively 0.053mg/L, 0.062mg/L, 0.064 mg/L is educed. Based on the regression relationship of total phosphorus,chlorophyll-a, total nitrogen, and the transparency,we compartmentalized the evaluation standard level of eutrophication in Miyun Reservoir.
