太原市PM2.5浓度与土地利用及植被覆盖的关系
Relationship between PM2.5 concentration and land use and vegetation cover in Taiyuan city
摘要
Abstract
This paper is aimed at exploring the source of air pollution in Taiyuan city and improving the urban air quality.The study processes PM2.5 concentration data,PM2.5 grid data and Landsat images-from 9 fully automatic pollution monitoring sub-stations in Taiyuan city from 2020 to 2021,and analyzes the relationship between PM2.5 and land use together with vegetation cover.The results show that the con-centration of PM2.5 is irregular with seasons.Specifically,the concentration peak appears in spring and winter,and the low ebb emerges in summer and autumn.Urban development,urbanization expansion and the increase of cultivated land area can cause the concentration increase of PM2.5,while the increase of woodland area can lead to the concentration decrease of PM2.5.By establishing the regression model of PM2.5 and vegetation cover,it is found that PM2.5 have a strong correlation with the two factors.关键词
