大气污染源排放时空分布特征及减排潜力分析

Analysis of spatiotemporal distribution characteristics and emission reduction potential of air pollution sources

在开展大气污染源时空分布特征研究时,如果不能及时获取目标城市的大气污染源类型,将直接降低对大气污染源时空分布特征的准确性。为此,提出了一种大气污染源排放时空分布特征及减排潜力分析方法。该方法首先确定研究对象,并进行区域概况分析,以确定相关污染源类型,并设置监测点以收集污染数据。然后,利用这些数据获取该研究区域大气污染源的排放时空分布特征,并详细分析该研究对象的减排潜力,为后续城市大气污染治理工作提供有力依据。研究结果表明,在安阳市,大气污染源整体呈现出冬夏两季污染严重、春秋污染程度较轻的双峰状态。从空间分布来看,大气污染程度较为严重且分布较为分散。然而,这个城市具有巨大的减排潜力,可通过取缔工业锅炉、提升工业单位污染物净化设备效率等手段来实现减排。这些结果为制定有效的大气污染治理措施提供了重要依据。

When conducting research on the spatiotemporal distribution characteristics of air pollution sources,if the type of air pollution source in the target city cannot be obtained in a timely manner,it will directly reduce the accuracy of the spatiotemporal distribution characteristics of air pollution sources.Therefore,a method for analyzing the spatiotemporal distribution characteristics and emission reduction potential of air pollution sources was proposed.This method first identified the research object and conducted a regional overview analysis to determine the relevant types of pollution sources,and set up monitoring points to collect pollution data.Then,these data to obtain the spatiotemporal distribution characteristics of air pollution sources in the study area was used,and the emission reduction potential of the research object was analyzed in detail,providing a strong basis for subsequent urban air pollution control work.The research results indicated that in Anyang City,the overall air pollution sources exhibited a bimodal state of severe pollution in winter and summer,and relatively mild pollution in spring and autumn.From the perspective of spatial distribution,the degree of air pollution was relatively severe and the distribution was relatively scattered.However,this city has enormous emission reduction potential,which can be achieved through measures such as banning industrial boilers and improving the efficiency of pollutant purification equipment in industrial units.These results provide an important basis for formulating effective air pollution control measures.
