Grey Clustering Assessment of Industrial Pollution Based on Triangle Whitenization Weight Function——Taking Jiangsu Province as an Example

This paper chose the industrial "three wastes"(waste gas,industrial waste water and industrial solid waste) as the research object.And waste gas,sulfur dioxide,soot,dust,waste water,chemical oxygen demand(COD),ammonia nitrogen,solid waste and hazardous waste were selected to establish the evaluation index system of urban industrial pollution.This paper based on triangle whitenization weight function,which classified the industrial pollution in 13 cities of Jiangsu Province into different grey classes and then had comprehensively grey clustering assessment.Research showed that,due to scale effect,structural effect and generalizedly technical effect,Nanjing,Suzhou and Wuxi were relatively seriously polluted,while Changzhou,Zhenjiang,Yangzhou,Taizhou,Nantong,Huaian and Xuzhou were generally polluted.As to Yancheng,Suqian and Lianyungang were just slightly polluted.
