水环境质量的模糊综合评价

FUZZY COMPREHENSIVE EVALUATION FOR ENVIRONMENTAL QUALITY OF WATER

在水环境质量综合评价中,计算隶属度时应考虑水质指标监测值的统计波动性,确定权值时应考虑权值的模糊性,进行模糊矩阵运算时宜选择加权综合运算模型。

The fluotuation of values of monitoring water quality and fuzryness of weights of pollution factors should be considered in the fuzzy comprehensive evaluation for water environmental quality because they have significant influcncoc on the calculation of membership and decision of weight.It is important to select operational model on which the fuzzy matrix is opcratcd.It is worth noting that the model M( · ? ) can get more satisfactory result which has weighted and comprehensive property than model M(∧ ,∨ ),M(· , ∨)andM(∧. ?).
