| 摘 要： | 大气环境质量问题一直是关注的环境问题之一,而灰色聚类分析方法在很多领域已有应用。本文对成都市大气环境监测数据进行评价：采用灰色聚类分析方法,将污染因子（SO2、NO2、PM10）进行综合评价,标准化污染因子及评价指标。白化函数得到各个污染因子每年的5×4矩阵,按照聚类系数来判定综合指标类型,并进行评价。为成都市综合大气...

| Abstract: | Atmospheric environmental quality is always paid attentions.Grey-clustering method has been applied in many fields.In this paper the atmospheric environmental monitoring data in Chengdu were evaluated using Grey-clustering method.The polluting factors such as SO2,NO2 and PM10 were comprehensively evaluated,and the polluting factors and evaluation index were standardized.By means of whitened function the annual 5×4 matrix of every polluting factor was obtained.According to the clustering coefficient,the type of comprehensive index was determined and then evaluated.It provided theoretical basis for analysis of atmospheric pollution in Chengdu. |
