系统聚类方法对大气污染地区的划分

Division of Air Pollution Areas by Systematic Cluster Method

当前国内经济快速发展的同时带来了环境质量下降等问题,地区间发展落脚点不同,受到的大气污染程度不同。从主要的大气污染监控物PM2.5、PM10、一氧化碳、二氧化碳、臭氧和二氧化硫6个方面构建大气污染地区分类的聚类评价指标体系,建立地区分类的聚类分析模型。并以北京、上海、海口、西安、佛山、酒泉、拉萨和重庆8个城市为例,应用评价指标的数据进行聚类分析,根据聚类结果提出具有针对性的环境保护建议.

The present rapid development of the domestic economy brings about problems such as the decline of environmental quality. The regional difference in the development focus leads to different degree of regional atmospheric pollution. Based on the six major atmospheric pollutants of PM2.5, PM10, carbon monoxide, carbon dioxide, ozone and sulfur dioxide, we construct an evaluation index system for air pollution area classification and build a cluster analysis model. We employ the data of the evaluation index to make a cluster analysis of eight cities: Beijing, Shanghai, Haikou, Xi'an, Foshan, Jiuquan, Lhasa and Chongqing, and then propose targeted environmental protection solutions based on the cluster analysis results.
