摘　　要：本研究利用ArcGIS软件,采用反距离权重法(IDW)对2014—2015年长三角地区PM_(10)、PM_(2.5)、SO_2和NO_2共4种大气污染物进行空间插值分析,探讨长三角地区大气污染物空间分布特征。结果表明:4种污染物浓度均呈现冬季>秋季>春季>夏季;长三角北部的江苏省城市PM_(10)、PM_(2.5)、SO_2和NO_2的浓度普遍高于浙江省;东部沿海地区普遍比中部内陆城市大气环境质量要好;长三角地区NO_2浓度普遍较高,地区差异不大。In this paper,using ArcGIS software,the inverse distance weight method(IDW)is used to analyze the spatial interpolation of PM 10,PM 2.5,SO 2 and NO 2 in the Yangtze River Delta from 2014 to 2015,and to explore the spatial distribution characteristics of air pollutants in the Yangtze River Delta.The results show that the concentrations of four pollutants are winter>autumn>spring>summer;the concentrations of PM 10,PM 2.5,SO 2 and NO 2 in Jiangsu Province in the north of Yangtze River Delta are generally higher than those in Zhejiang Province;the atmospheric environment quality in the eastern coastal areas is generally better than that in the inland cities in the middle;the concentrations of NO 2 in the Yangtze River Delta are generally higher,with little regional difference.
