摘要
采用全国空气污染监测站点监测所得的污染物实际浓度和空气污染物排放量作为空气质量系统的衡量指标,重点构建了空气质量评价体系。同时,构建了经济发展和城市化的综合评价指标体系,运用耦合度和协调度模型评估了全国283个城市的耦合度与协调度,并对三系统的综合得分、耦合度和协调度得分的空间分布特征进行了分析和讨论。研究发现:城市之间的经济发展和城市化水平的综合得分差异很大,且在空间分布上存在显著的集聚效应,形成了明显的"中心—外围"的空间发展格局。从空气质量方面来看,我国雾霾问题较为严重的地区主要集中于东部和南部。从耦合度和协调度的空间分布来看,两者分布大致相同,低值区主要分布在我国西南地区和中部地区,如河南和川桂黔滇地区等。高值区主要集聚于省会城市和经济发达的东部沿海城市,如北京、上海和杭州等。
We emphasized on the evaluation indicators of air quality system by using the concentration of pollutants monitored by China National Environmental Monitoring Center(CNEMC)as well as industrial pollutant emissions.What′s more,the systems of economic development and urbanization were also constructed.We calculated the values of the three systems of economic development,urbanization and air pollution,the coupling degree values,and the coordinated degree values,and then analyzed and discussed the spatial distribution of values of three systems,the coupling degree,and the coordinated degree,respectively.The findings are the followings.There were significant differences in the values of the systems of economic development and urbanization.They presented significant spatial clusters,namely the spatial pattern of the core-periphery structure.In the view of the system of air quality,it showed that the remarkable spatial pattern that the haze-fog event occurred frequently in the east and in the south.With respect to the spatial distribution of the coupling degree and the coordinated degree values,they had the similar spatial patterns.The notably low values concentrated in the area of the southwest China and the cities of the central China,for example,Henan,Sichuan,Guangxi,Guizhou and Yunnan while the high values were found in the capital cities and the economically-developed coastal cities such as Beijing,Shanghai and Hangzhou.
