【摘要】：以京津冀各城市大气污染物年均质量浓度及新的空气质量标准为基础,采用承载率评价法对各城市2013年~2015年大气环境承载力进行评价及预警判断。同时采用相关系数法,对京津冀区域及各城市大气环境承载影响因素进行相关分析。结果表明:(1)2013年~2015年我国京津冀区域大气环境超载严重,但是形势逐步好转。(2)该区域大气环境超载预警级别整体较高,中南部地区比北部地区严峻。(3)近年该区域大气环境综合承载指数与自然因素显著相关,与农业人口、机动车氮氧化物排放量等人为因素相关性也较高。京津冀区域应从农村大气污染(散煤和秸秆燃烧、道路扬尘等)、城镇机动车尾气排放防控等方面加大治理力度。
[Abstract]:Based on the average annual concentration of air pollutants and the new air quality standard in each city of Beijing, Tianjin and Hebei, the carrying capacity of atmospheric environment in cities from 2013 to 2015 was evaluated by using the method of carrying capacity evaluation and early warning judgment. At the same time, correlation coefficient method is used to analyze the influence factors of atmospheric environment carrying capacity in Beijing-Tianjin-Hebei region and cities. The results show that the atmospheric overloading in the Beijing-Tianjin-Hebei region from 2013 to 2015 is serious, but the situation is gradually improving. In recent years, the comprehensive bearing index of atmospheric environment in this region is significantly related to natural factors, and also to human factors such as agricultural population, motor vehicle nitrogen oxide emissions and so on. In the area of Beijing-Tianjin-Hebei, it is necessary to strengthen the control of air pollution in rural areas, such as the burning of coal and straw, the dust emission from roads and so on, and the prevention and control of motor vehicle exhaust emissions in cities and towns.
