时空变化特征的城市空气污染趋势研究

Analysis on Urban Air Pollution Trend Considering Temporal and Spatial Variation Characteristics

城市化进程的加速造成了大量城市空气污染,严重威胁了人们身体健康,及时了解城市空气污染情况是有关部门治理空气污染的必要参考,是环境领域研究的重点问题,因此文章在考虑时空变化特征的前提下对城市空气污染趋势进行分析。首先,介绍了数据来源和城市空气污染研究思路;其次,以京津冀城市群为监测目标,获取2018年-2020年城市空气污染数据,分析污染组成物及污染相关性及京津冀城市群的城市空气污染的时空变化特征;最后,根据监测结果分析京津冀城市群的城市空气污染情况。

The acceleration of urbanization has lead to severe urban air pollution,which seriously threatens people s health.Timely understanding of urban air pollution is a necessary reference for relevant departments to control air pollution,and is a key issue in the field of environmental research.Therefore,this paper analyzes the trend of urban air pollution under the premise of considering the characteristics of temporal and spatial changes.First of all,the research ideas of data sources and urban air pollution are introduced.The Beijing-Tianjin-Hebei urban agglomeration is used as the monitoring target,and the urban air pollution data from 2018-2020 will be obtained to analyze the tempo-spatial changes in urban air pollution in urban agglomerations.Finally,it analyzes the urban air pollution of the Beijing-Tianjin-Hebei urban agglomeration based on the monitoring results.
