摘　　要：运用长株潭地区2013年的空气质量指数(Air Quality Index,简称AQI)资料为研究基础,对每日空气质量指数、空气质量级别等的不同时间尺度变化差异进行了深入分析研究。结合湖南省地面气候资料及观测资料等,对污染日进行了天气学分型,为长株潭地区污染日的预报预警提供参考依据。结果表明:长株潭地区的首要污染物以可吸入颗粒物为主,污染情况以冬季、秋季最为严重;运用合成分析方法对秋、冬季的污染天气进行分型,从湿度、风场等要素场研究湖南污染的典型环流背景。Based on the data of Air Quality Index（ Air Quality Index,referred to as AQI） in 2013,the difference of air pollution index and air quality level is analyzed in this paper. Based on the meteorological data and observation data of Hunan Province,the meteorological cause of a high pollution weather process was analyzed. The results showed that the main pollutants in the area of Chang Zhu Tan area were still dominated by the particulate matter,which was the most serious in winter and autumn,and the pollution weather of autumn and winter was studied by using the synthetic analysis method. The paper is divided into the typical circulation background of the pollution in Hunan,such as the humidity,the wind field and so on.
