摘　　要：灰关联分析法是水质评价系统中的重要评价方法。针对传统灰关联分析法存在静态分辨系数均质化,关联度比较差异性低,因子权重评价影响程度低等缺点,提出了引入动态分辨系数和综合评价指标的改进型灰色关联分析法,并应用于四湖流域湿地环境监测系统MIS软件部分,与传统灰关联分析法和聚类因子分析指标及结果进行了对比,结果表明,改进型灰关联分析法有效地提高了评价结果的可靠性和准确性。Grey relational analysis method is an important method to evaluate the water quality in the evaluation system.The traditional method of grey correlation analysis has several shortcomings,including the static resolution coefficient homogenization,the low correlation comparison difference and the low influencing degree of factors weight.This paper puts forward an improved grey relational analysis method by introduction of dynamic resolution coefficient and comprehensive evaluation indexes.Then the method is applied in the MIS software part of Four Lake Basin wetland environment monitoring system,and compared with the traditional grey correlation analysis method and the clustering factors analysis method.The results show that the improved grey correlation analysis method effectively improves the reliability and accuracy of the evaluation results.
