摘　　要：传统的灰色聚类法,当指标数较多时,设计白化函数的工作量很大,实际使用不便。为减少白化函数的设计个数并使之规范化,设定适当的指标参照值和指标值的规范变换式,对灰类和白化数进行规范和归类,从而减少工作量提高效率。以山东省水环境安全评价为例,利用基于指标规范值的灰色聚类方法对水安全进行综合评价,并与属性识别理论和TS-SVM模型的结果进行了对比。结果表明:与传统的灰色聚类法相比较,该方法将115个白化函数减少到25个,工作效率提高4倍,是有效的水安全评价分析工具。In traditional grey clustering method,the design of whitening function often involves a heavy workload when there are quite a few indicators.It is inconvenient in actual use.In order to reduce the number of white functions and make them standardized,appropriate transform of reference indicators and transformation forms will be set and grey type and white functions will be standardized and classified.In this way,the workload can be reduced and efficiency improved.This paper,making Shandong province as an example,assesses the water safety based on grey clustering method with standardized indicator and compare with the result of attribute recognition theory and TS-SVM model.The results indicate that this approach reduces the number of whitenning fuction from 115 to 25,and improves the efficiency by 4 times compared to the traditional grey clustering method.It is an effective tool for water safety evaluation and analysis.
