【摘要】：京津冀地区是全国能源消耗强度最大、大气污染最严重的区域,是全国钢铁、火电、水泥等重工业集中发展区。考虑到京津冀严峻的大气环境形势和区域间大气污染物跨界传输的现状,开展京津冀大气污染协同治理需要明确大气污染排放的空间集聚特征。基于京津冀2013年企业污染源环境统计数据,应用核密度空间分析工具模拟了京津冀工业源大气污染排放空间集聚特征。研究结果显示:(1)京津冀钢铁冶炼行业、电力热力行业、非金属制品业以及基础化工是京津冀主要大气污染排放行业;(2)工业源大气污染排放主要集中在唐山、天津、邯郸和石家庄,合计占到整个区域SO_2和NO_x排放的60%和64%;(3)京津冀区域SO_2和NO_x排放密度高于5 t/km2的区域分别占整个区域面积的19.3%和19.1%,在唐山、石家庄、邯郸、天津、保定、廊坊等形成集中的大气污染集聚区。针对上述重点污染行业和污染排放密集区域,应开展区域协同综合治理,通过区域间排污权交易、绿色金融、产业结构优化升级等措施,提升区域大气环境质量。
[Abstract]:The Beijing-Tianjin-Hebei region is the region with the largest energy consumption and the most serious air pollution. It is the concentrated development area of heavy industry such as iron and steel, thermal power, cement and so on.Considering the severe situation of atmospheric environment in Beijing-Tianjin-Hebei and the present situation of transboundary transport of air pollutants between regions, it is necessary to make clear the spatial accumulation characteristics of atmospheric pollution emissions in order to carry out the coordinated control of air pollution in Beijing-Tianjin-Hebei.Based on the environmental statistics of pollution sources of enterprises in Beijing, Tianjin and Hebei in 2013, the spatial accumulation characteristics of air pollution emissions from industrial sources of Beijing, Tianjin and Hebei were simulated by using the nuclear density spatial analysis tool.The results show that the Beijing-Tianjin-Hebei iron and steel smelting industry, the electric power thermal industry, the non-metallic products industry and the basic chemical industry are the main air pollution emission industries in Beijing-Tianjin-Hebei province.Handan and Shijiazhuang, which together account for 60% and 64% of the total SO_2 and NO_x emissions in the whole region. The areas with SO_2 and NO_x emission densities higher than 5 t/km2 in the Beijing-Tianjin-Hebei region account for 19.3% and 19.1% of the total area, respectively. In Tangshan, Shijiazhuang, Handan, Tianjin, Baoding,Langfang and other forms of concentrated air pollution agglomeration area.In view of the above key pollution industries and pollution-intensive areas, we should carry out regional coordinated and comprehensive management to improve the regional atmospheric environment quality by means of interregional emissions trading, green finance and industrial structure optimization and upgrading.
