2014-2022年贵阳市空气质量时空变化特征及影响因素分析
Temporal and Spatial Characteristics of Air Quality in Guiyang City from 2014 to 2022 and Analysis of Influencing Factors
摘要
Abstract
In recent years,with the acceleration of urbanization and population growth,urban air pollution has become increasingly prominent and has received widespread attention.In this study Guiyang City is taken as a research subject,the change characteristics of six major air pollutants(SO2,NO2,O3,PM10,CO and PM2.5)and two major atmospheric pollutants(PM10 and PM2.5)were studied from 2014 to 2022 in terms of temporal and spatial dimensions,and their impacts on air quality were also studied.The results indicated that the major air pollutants exhibited higher levels in spring and winter and lower levels in summer and autumn,with an overall continuous decline from 2014 to 2022.Spatially,the air quality index(AQI)in the central urban area of Guiyang City showed a characteristic of being"low in the north and south,high in the center".The main factors influencing the AQI include PM2.5,PM10,NO2,temperature,precipitation,and total energy consumption.The study provided scientific evidence for the management and protection of air quality in Guiyang City,offering robust data support for policy formulation and implementation.关键词
