摘　　要：以海西城市群可吸入颗粒物(PM10)为研究对象,分析PM10的时空分布特征及其与气象要素、社会经济要素的相关关系.结果表明:海西城市群PM10年均浓度总体呈逐年下降趋势,与2014年相比,2018年海西城市群整体平均降幅比例为29.54%,颗粒物污染水平有显著改善.PM10浓度季节性特征明显,春季和冬季浓度较高,秋季居中,夏季最低.月均浓度呈“W”型的变化趋势,全年中1月、12月PM10浓度相对较高,6月、7月PM10浓度相对较低.海西地区南部、北部城市PM10浓度呈较高的势头,而沿海中部城市PM10浓度水平较低.10个城市中,温州PM10年均浓度最高,厦门PM10年均浓度最低.城市间PM10浓度呈显著正相关性,平均气温、平均风速是影响PM10浓度变化的重要因素.With the inhalable particulate matter(PM10)in the urban agglomeration on the Western Coast of the Taiwan Straits as the research object,the temporal and spatial distribution characteristics of PM10 and its correlation with meteorological elements and socioeconomic factors were analyzed in this paper.The results showed that the average annual PM10 concentrations of the urban agglomeration showed a downward trend year by year.Compared with 2014,the overall average decrease rate of the urban agglomeration in 2018 was 29.54%,and the level of particulate pollution has improved significantly.The concentrations of PM10 have obvious seasonal characteristics,with higher concentrations in spring and winter,the middle in autumn,and the lowest in summer.The monthly average concentrations showed a"W"-shaped change trend.The PM10 concentrations were relatively high in January and December while relatively low in June and July.The concentrations of PM10 in the southern and northern cities were higher whereas those in the central coastal cities were lower.Among the ten cities,Wenzhou has the highest annual average concentrations of PM10,while Xiamen has the lowest.There is a significant positive correlation between the concentrations of PM10 in different cities,and the average temperature and average wind speed were important factors influencing the change of PM10 concentrations.
