摘要：为有效处理浮游植物型湖泊富营养化评价中各评价指标、评价级别以及各级别对应的水质标准浓度的不确定性，将集对分析理论运用于湖泊富营养化的水质评价中。在确定各指标权重时，将统计学中的相关关系理论引入该模型，通过计算各评价指标与叶绿素的相关关系来计算各水质评价指标在富营养化评价中所占权重，建立了基于相关系数定权的集对分析模型。最后通过国内5个湖泊的水质实测数据，将该模型与模糊评价方法，灰色评价方法进行比较验证，说明该模型简单实用、评价结果合理。

Abstract: In order to solve the uncertainty of the assessment index,order and the assessment standard of each order of lake’s eutrophication,a method of set pair analysis was adopted in the assessment of lake’s eutrophication in this study.Correlation theory of statistics was used in this model for lake’s eutrophication assessment.The weight of each water quality index was calculated according to the correlation coefficient between each water quality index and chlorophyll.this method only suits the lakes of phytoplankton type.By compared with fuzzy assessment method and grey assessment method using measured data in 5 lakes in China,the method is validated to be simple and practical with sound assessment results.
