摘要
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.关键词
