- 摘要:
- 随着社会的进步和工业的发展,人为因素对大气环境的影响日益突出。驻马店市作为河南省中原城市群中重要的、以平原为主的农业大市,其空气质量在历次大气污染过程中易受到华北、江淮等地区的影响。为响应政府大气污染防治任务的相关要求,定量评价驻马店市空气自净能力,利用修正A值法从年度、季节性两个时间维度和容量、容量紧缺度两个指标维度研究该区域十三五期间的大气污染SO2、NO2、PM2.5、PM10四类污染物的大气环境容量及容量紧缺度,对计算结果进行讨论和分析,为十四五驻马店市的大气污染防治工作提供参考。研究表明:(1)A值和四类污染物的环境容量有明显的季节性特征,表现为秋冬季A值和环境容量较低,春夏季节A值和环境容量较高;(2)两种气态污染物SO2、NO2在四季中紧缺度指数数值变化不大,PM10紧缺度指数表现为冬季较高,PM2.5紧缺度指数表现为春冬季较高,尤其是PM2.5冬季紧缺度指数达到8.9201;(3)四类污染物中除两类气态污染物容量紧缺度指数逐年降低,两类颗粒物容量紧缺度波动下降。
- Abstract:
- With the advance of society and the development of industry, the impact of human factors on the atmospheric environment has become increasingly prominent. Zhumadian is one of the most important agricultural cities in Henan Province. Its air quality is easily affected by North China, Jianghuai and other regions in the process of previous air pollution. In response to the relevant requirements of the government’s task of air pollution prevention and control, this paper quantitatively evaluates the air self-purification capacity of Zhumadian, and uses the modified A-value method to study the air environmental capacity and capacity shortage of four pollutants(SO2, NO2, PM2.5 and PM10)during the “13th five year plan period”from two time dimensions of annual and seasonal and two index dimensions of capacity and capacity shortage. The discussion and analysis can provide reference for the air pollution prevention and control in Zhumadian during the “14th Five Year Plan period”. The results show that:(1)The A-value and the environmental capacity of the four kinds of pollutants have obvious seasonal characteristics, which are lower in autumn and winter and higher in spring and summer;(2)the shortage index of two kinds of gaseous pollutants SO2 and NO2 changed little in the four seasons, PM10 shortage index was higher in winter, PM2.5 shortage index was higher in spring and winter, especially that of PM2.5 reached 8.9201 in winter.(3)The annual capacity shortage index of such two air pollutants decreased year by year, and the other two types of particulate capacity fluctuated with a trend of decreasing.
