Analysis of Influencing Factors of Environment Quality in Dalian Based on Grey Correlation and Systematic Clustering
The degree of correlation between representative indicators such as society,economy,nature,population,energy resource and pollution emissions in Dalian and the quality of environment is quantitatively analyzed by using gray relevance and systematic cluster analysis method.The results show that the correlation between socio-economic development and environmental quality in Dalian is medium,the correlation between economic indicators and environmental quality indicators is strong,the correlation between social,population and pollution emission indicators is medium,and the correlation between energy and natural indicators is weak.Jinpu New Area,Ganjingzi District and Changxing Island are potential environmental risk areas that need to focus on environmental quality trends.Although Pulandian District,Wafangdian City and Zhuanghe City belong to low-emission areas,the environmental quality risk is relatively large,and environmental risk management and control should be further strengthened.
