采用加速遗传算法和Logistic曲线建立了富营养化评价模型。利用该模型对乌梁素海1996 ~ 2003年不同季节的富营养化水平进行了预测。在此基础上，分析了乌梁素海富营养化主控因子的季节变化。结果表明，1996 ~ 2003年，各主控因子均保持四级水平，除总磷波动较大外，其余各因子均呈上升趋势。水质总体水平已超过四级，接近五级。
The assessment model of eutrophication has been established by used of Accelerating Genetic Algorithm and Logistic Curve in this paper. According to the model, the eutrophication levels of the different season from 1996 to 2003 in Wuliangsuhai Lake have been concluded. Based on the level, the season-year changes of the eutrophication main-control factors in Wuliangsuhai Lake have been analyzed. The result shows that all the main-control factors of eutrophication remain forth level and except that the total phosphorus has great fluctuation, the others are rising by and by from 1996 to 2003. The whole levels of the water quality have beyond the forth level and close to the fifth level.
