摘要
基于2012-2014年湖北省环境空气质量监测统计数据,根据污染浓度水平,利用ArcGIS软件分析湖北省大气颗粒物污染空间分布特征,并利用SPSS软件对大气污染物SO_2、NO_2、O_3、CO、PM_(2.5)和PM_(10)的相关性进行分析。结果表明:2012-2014年期间,湖北省PM_(10)年均浓度总体呈上升趋势,超标城市几乎分布于湖北省各区域;武汉、荆州、宜昌3个城市PM_(2.5)与PM_(10)、SO_2、NO_2、CO均呈较高的正相关性,鄂州、恩施、黄冈、黄石、荆门、十堰、随州、咸宁、襄樊和孝感10个城市PM_(10)与NO_2、SO_2均呈正相关性。文章的分析结果可为湖北省改善环境空气质量,降低颗粒物浓度水平提供基础信息和建议。
Based on the monitoring data of ambient air quality from 2012 to 2014, the spatial distribution characteristics of atmospheric particulate pollution in Hubei Province were analyzed by ArcGIS software. And the correlation among SO2, NO2, O3, CO, PM2.5 and PM10 were analyzed by SPSS analysis software. The results showed that the average concentration of PM10 in the Province was increased from 2012 to 2014, and cities where average concentration of PM10 exceeds the standard are mostly distributed in each region of the Province. The relative analysis showed that, in the city of Wuhan, Jingzhou and Yichang, there were significant positive relationships between the average concentration of PM2.5 and the average concentration of PM10, SO2, NO2 and CO. In other ten cities, the average concentration of PM10 was positive relevant to the average concentration of NO2 and SO2. The results of this study can provide basic information and recommendation for improving the quality of air environment and reducing the concentration level of particles in Hubei Province.
