Aeruginosa increased with the increased initial P concentration in the media;② Under the constant N concentration, the phosphorus uptake of M. aeruginosa was correlated positively with the initial P concentration;③ Under the constant P concentration, the accumulation of phosphorus by M. aeruginosa was correlated negatively with the initial N concentration, but the trend was not obvious and the effect of initial N concentration on the uptake P quantity became ruleless when the initial N concentration reached a higher level (21 mg/L).

结果显示，①氮磷比不变时，随着起始磷浓度的增加，铜绿微囊藻对正磷酸盐蓄积量也逐渐增加，成明显正相关；②氮浓度不变时，铜绿微囊藻对正磷酸盐的蓄积效果与磷浓度正相关；③而同一磷浓度下，铜绿微囊藻对正磷酸盐的蓄积效果与氮浓度负相关，但氮浓度超过21 mg/L时，氮浓度对于铜绿微囊藻蓄积磷的效果影响变得不规则。

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.
