介绍了灰色关联分析法在水质评价中的运用,并进行了改进.引入斜率的概念消除传统方法对关联度序列的影响,并确保关联度的保序性,并且根据天津市引滦输水沿线氮、磷污染严重的水质特点,调整水质指标的权重,得到的水质评价结果不仅比单因子评价、综合指数评价等常用简易方法更合理,也比传统灰色关联度方法的评价结果体现出更好的关联度差异性.

This paper brought out improvement with introduction on the application method of gray relational analysis in the water quality assessment. The method introduced the concepe of slope ratio to eliminate the effect of traditional GRM on sequence of associative degrees,ensured the isotonicity,and adjusted the weight in accordance with the water delivery area of Luanhe River in Tianjin characteristic of heavy pollution of nitrogen and phosphorous. The results were not only more reasonable comparing with common assessment methods as single index and comprehensive index,but also more distinguished associative degrees than traditional GRM methods.
