摘    要:倍斜率聚类法依据灰色系统理论和模糊数学理论的有关基本原则,以宽域式结构建立隶属函数,函数的左侧斜率小于右侧斜率,以大气环境质量评介为例说明了该法的具体应用,并与模糊综合评判法和灰色聚类法进行了比较,结果表明,该法更为合理,实用。

关 键 词:倍斜率聚类法  环境质量  评价

Abstract:Based on the principles of the white function construction in the grey system theory and the grey classification,and the weight thought from fuzzy comprehensive assessment,a new method for assessing environment quality,i.e.the twice-slope classification,was suggested.A successful example of using the new method to assess air environment quality was given in this paper. A function based on the twice-slope method was established,and the value range of pollutants in the function was expanded with a full use of information.Compared with other methods,the new method made the use of information much fuller and gave the conclusion more reasonable and credible. It could also overcome the defects of both fuzzy comprehensive assessment and grey classification and have more practical use in environment quality assessment.
Keywords:twice-slope classification  fuzzy comprehensive assessment  grey classification  environment quality assessment
