京津冀区域人口、经济、能耗与大气环境污染相关性分析

Analysis of Correlation Relationship of Population,Economy,Energy Consumption and Atmospheric Environmental Pollution in Beijing-Tianjin-Hebei Region

利用京津冀污染物浓度和排放量与人口、经济、能耗对应关系,系统分析了京津冀区域人口、经济及能源消耗对大气环境污染影响分析。人口密度越大,人均GDP越低,第二产业结构越重,能源消耗量越大,污染物排放量越大。北京人口密度集中,机动车保有量大,主要为生活废气和机动车废气污染,产生大量NO_x、颗粒物(PM)、CO、碳氢(CH)化合物,主要造成PM、NO_x、O_3污染。天津属于人口相对集中、经济较为发达地区,二、三产业结构相当,人口消耗和交通带来的生活废气和机动车废气主要造成O_3污染,工业污染源造成的PM、CO、NO_x污染。河北密集高能耗产业,煤炭消费量大,污染物排放量大,污染严重,大气环境污染主要为工业污染,工业污染造成PM、CO、NO_x、SO_2、O_3污染。

The impact of population, economy and energy consumption on the atmospheric pollution in Beijing-Tianjin-Hebei area was systematically analyzed. When the population density was greater, the per capita （GDP） was lower, the proportion of the second industrial structure was heavier, the energy consumption was greater and the pollutant emissions were greater. Beijing had a large population density and a large quantity of motor vehicles. It mainly produced pollutants such as nitrogen oxides （ NOx ）, particulate matter （PM） , carbon monoxide （CO） and hydrocarbon （CH） compounds, mainly PM, NO and ozone （03 ）. Tianjin was a relatively concentrated population and economically developed area. The second and third or industrial structure was nearly the same. The population consumption and the traffic brought exhaust gas, motor vehicle emissions, 03 pollution and industrial pollution caused by PM, CO and NOx pollutions. Hebei area had intensive energy-intensive industries with serious pollutions. Atmospheric pollution was the main industrial pollution and the industrial pollutions were caused by PM, CO, NO, SO2 and O3 pollution.
