中文摘要：
在模糊综合评价方法的基础上,提出范数灰关联度的概念.通过范数的近距和远距,获取各因子的关联度和权重系数,充分利用了样本的共性和个性信息.利用灰关联度赋权的模糊综合评价法对延安市境内延河流域上的8个监测断面进行水质评价,取得了较好的结果,并与熵权模糊综合评价法、灰色关联分析法进行比较,结果更加客观、合理.
英文摘要：
Based on the fuzzy synthetic evaluation, a new weight evaluation method com- bining grey theory with norm was established. The correlation and weight coefficients of factors were obtained by the near and far distances of norm theory, which made full use of the commonness and individuality of factor information. The water quality of eight sections of Yan River in Yah An territory was assessed by the method. Compared with entroy-based fuzzy synthetic evaluation and grey correlation analysis methods, the assessment result was objective and reasonable.
