摘要
以哈尔滨市大气颗粒物2014至2019年的检测数据为基础,针对采暖期对大气颗粒物污染特征进行分析。结果表明,与非采暖期相比,哈尔滨市采暖期的颗粒物浓度更高,进一步说明了化石燃料与生物质的燃烧是引起采暖颗粒物污染的主要因素。在采暖期,哈尔滨市区与周边市区相比,其颗粒物平均浓度均高于周边地区,香坊区的PM10、PM2.5浓度最高。在采暖期,每日大气细颗粒物PM10和PM2.5浓度的变化较大。采暖期和非采暖期,PM10和PM2.5均呈现双峰变化趋势。
Based on the detection data of atmospheric particulate matter in Harbin from 2013 to 2018,the atmospheric particulate matter pollution characteristics were analyzed for the heating period.The results show that compared with the non-heating period,the concentration of particulate matter in the heating period in Harbin is higher,which further illustrates that the combustion of fossil fuels and biomass is the main factor causing pollution of heating particulate matter.During the heating period,compared with the surrounding urban areas,the average concentration of particulate matter in the urban area of Harbin is higher than that of the surrounding areas,and the concentrations of PM10 and PM2.5 in Xiangfang District are the highest.During the heating period,the daily concentration of fine particulate matter PM10 and PM2.5 varies greatly.During heating and non-heating periods,PM10 and PM2.5 showed a bimodal change trend.
