摘　　要：利用2015年福州主城区6个大气国控点的6种主要大气污染物逐时监测数据、气象数据及空间基础数据等,通过增设站点后进行空间插值的方法分析大气污染物浓度的空间分布特征。结果表明:福州市大气中PM_(2.5)、PM_(10)最高值分别为35.57μg/m^3和62.35μg/m^3,高浓度区域集中在主城区中心和近郊区,其中台江区污染程度相对较高;O_3最高值为94.85μg/m^3,较高浓度主要集中在晋安区内海拔较高的森林地区;CO、SO_2和NO_2最高浓度低于一级标准浓度限值,高浓度区域分布在主城区中心。Based on the monitoring data of 6 pollutants from 6 national sampling sites,the meteorological data and basic spatial data in the main urban area of Fuzhou in 2015,the spatial distribution characteristics of the pollutants were analyzed by using spatial interpolation method after adding more sites.Results showed that the maximum of PM2.5 and PM10 were 35.57μg/m^3 and 62.35μg/m^3,respectively.The areas of high concentration were in the central city and the suburbs.The pollution in Taijiang district was relatively serious.The maximum of O3 was 94.85μg/m^3,and the high concentration area was mainly in high altitude forest in Jinan district.The highest concentrations of CO,SO2 and NO2 were all below the corresponding standard limits of first grade,and the high concentration area was in central city.
