摘　　要：利用海峡西岸10个城市2014-2017年PM2.5监测数据进行分析,分析探讨PM2.5时空分布情况,并对可能影响PM2.5浓度的气象、社会及经济等因素进行相关性分析.结果表明:从时间分布来看,海峡西岸10个城市年均PM2.5浓度均呈下降趋势,季均浓度总体上表现为冬季>春季>秋季>夏季,月均PM2.5浓度为6-7月最低,1-3月最高.从空间分布来看,不同地区年均PM2.5浓度值总体上表现为温-丽-衢>梅-潮-汕-揭>福-厦-泉,空间上呈现北>南>中的分布特征.浙江省不同城市年均PM2.5浓度表现为衢州市>温州市>丽水市;福建省不同城市年均PM2.5浓度表现为厦门市>福州市≈泉州市;广东省不同城市年均PM2.5浓度表现为揭阳市>潮州市>梅州市≈汕头市.国内生产总值、人均生产总值、全社会机动车拥有量可能是影响海峡西岸主要城市PM2.5浓度变化的主要因素.In order to discuss the temporal and spatial distribution of PM2.5,the PM2.5 monitoring data of major cities on the Western Coast of the Taiwan Straits from 2014 to 2017 and the meteorological,social and economic factors which may affect PM2.5 concentration were analyzed.Temporal variations indicated that the average annual PM2.5 concentration in these major cities decreased gradually during 2014-2017.The seasonal variation of PM2.5 concentration in these major cities generally decreased in the order of Winter>Spring>Autumn>Summer.Higher values of monthly concentrations of PM2.5 occurred from January to March,and lower values were generally observed from June to July.Spatial variations suggested that the average annual PM2.5 concentration in different regions on the Western Coast of the Taiwan Straits decreased following the sequence of Wenzhou-Lishui-Quzhou>Meizhou-Chaozhou-Shantou-Jieyang>Fuzhou-Xiamen-Quanzhou.Spatial distribution characteristics were presented in north>south>middle.The average annual PM2.5 concentrations in different cities were in the order of Quzhou City>Wenzhou City>Lishui City in Zhejiang Province,and Xiamen City>Fuzhou City≈Quanzhou Ctiy in Fujian Province,and Jieyang City>Chaozhou City>Meizhou City≈Shantou City in Guangdong Province.Gross domestic product(GDP),per capita GDP and vehicle ownership of the whole society may be the main factors influencing the variations of PM2.5 in these major cities.
