摘要研究大气污染物有利于人们了解大气污染物的特性和污染特征，这对于人们对大气污染的防控有十分重要的意义。为了解江苏北部冬季大气污染物浓度水平及变化规律，本文统计了2015年冬季五个城市（徐州、盐城、宿迁、淮安、连云港）28个监测站每天四个时间点的SO2、NO2、O3、PM2。5、PM10和CO的实时常规环境监测数据，通过分时段分析AQI、主要气态污染物浓度及颗粒物浓度的时空变化特征，得到苏北地区冬季大气环境污染物的变化特征及成因。结果表明：苏北五市冬季的大气污染物浓度很高，五个城市采暖期和非采暖期主要大气污染物的浓度对比显著，采暖期燃煤对环境空气质量的影响十分显著。苏北五市冬季的自然气象条件不利于环境空气质量的改善，苏北五市冬季空气污染情况依然不容乐观。72923

Analysis of Atmospheric Pollutants’ Temporal and Spatial Variation Characteristics in Winter in Northern Jiangsu Province

Abstract Study of atmospheric pollutants is helpful for people to understand the characteristics of atmospheric pollutants and pollution characteristics, which has the very vital significance for the people to the prevention and control of atmospheric pollution。 To understand winter atmospheric pollutants concentration level and change rule in northern Jiangsu, this article statistics five cities (Xuzhou, Yancheng, Suqian, Huaian, Lianyungang) 28 monitoring station four hours of SO2, NO2 and O3, PM2。5 and PM10 and CO routine environmental monitoring data every day in the winter of 2015, the spatial and temporal variations of real-time AQI , the main gaseous pollutants concentration and particle concentration was analyzed through period of time, getting characteristics and genetic analysis of the change of the atmospheric pollution of the environment in winter of north Jiangsu 。 Results show that there is a  high concentrations of air pollutants in winter in five city of north Jiangsu ,the main atmospheric pollutants concentration in heating period and heating period of five cities contrast remarkably, the coal in the heating period has very significant impact on ambient air quality 。 The winter natural weather conditions in five cities of northern Jiangsu province makes against the improvement of environmental air quality。 The air pollution situation of five cities in winter of northern Jiangsu is still not optimistic。
