以阳澄湖水质分析为例，利用改进密切值法分别对其东、中、西3个湖区湖体水质进行评价。结果表明，在复杂的湖泊生态系统水质评价中，该方法不仅具有模型构建简便灵活、计算量小、结果直观的特点，而且区别于以往笼统的将不同时段、不同区域湖体水质判断为某一类标准的评价模式，能够客观准确地分析不同时空的水质分布规律，预判水质变化趋势，同时区别于将污染指标等权处理或忽略指标权重的评价方式，通过引进熵权法计算权重判断主要污染因子，使湖泊生态系统水质评价结果更真实合理。

The modified osculating method was used for the analysis of the water quality of the Yangcheng Lake as an exemplary wa-ter body.Evaluation of the east,middle,and west area of the lake water highlighted the advantages of the osculating method for eval-uating water quality of complex lake ecosystem.This method uses a simple and flexible model and requires only minor amount of cal-culation.The result is direct and visual.Compared with previous methods which utilize a general model for evaluating water bodies that are different in time and in space,the modified osculating method is capable of providing more accurate and objective evaluation for the water distribution law in different time and in space,and of predicting the change trend of water quality.At the same time,it calculates entropy weight to determine the main pollution factors,which is different from the evaluation method of equal index weight or ignored index weight.It could make the evaluation result on water quality of lake ecosystem more reasonable.
