摘　　要：针对模糊评价中对多因子赋权时因计算繁琐,工作量大,未考虑多个评价对象间联系等缺陷,提出利用熵权法对多评价因子赋权的新思路,建立了基于熵权的属性识别模型,并用此模型对福州市山仔水库的水质进行评价,比较了利用熵权法与传统的评价因子赋权的差异。此模型为湖泊水质的富营养化评价提供一种简便实用的评价方法。Considering the difficulties of calculation using fuzzy synthetic evaluation method and the relationship among evaluators being ignored,a new weight evaluation process using entropy method was established.Aiming at the water quality assessment on Shanzi Reservoir,the differences of entropy method and the traditional method were compared in the weight calculation of evaluating indicators using the fuzzy mathematics.This model provides a simple and pracical method for evaluating eutrophication of water in lakes.
