基于GIS的石家庄市雾霾分析

Analysis on the Haze of Shijiazhuang City Based on the GIS

为了得出雾霾气象成因机制、影响因素和时空分布特征,以石家庄市区与郊县为研究区域,将2013年9月至2016年12月石家庄市各市区、郊县的PM2.5历史监测数据中的有效数据进行了数据分析处理得到雾霾浓度数据,还有温度、降水、风速、地形和人口密度等数据,运用GIS分析的方法,模拟绘制石家庄雾霾的时空分布图、雾霾与各影响因子的专题对比图,得到雾霾形成机制的因子、雾霾的时空分布规律、雾霾季节变化特征、雾霾与地形间的关系等;运用数据分析软件OriginPro8.SR3分析雾霾浓度与风速数据、降雨数据、温度数据间的相关性。

In order to further obtain the formation mechanism,influencing factors and spatial and temporal distribution characteristics of haze meteorology,this paper takes Shijiazhuang city area and suburban counties as the research object.From September 2013 to December 2016,effective data in PM2.5 historical monitoring data of all urban areas and suburban counties of Shijiazhuang city were analyzed and processed to obtain haze concentration data,temperature data,precipitation data,wind speed data,DEM data,population density data and other methods of GIS analysis,the spatial and temporal distribution map of haze,the thematic comparison map of haze and the formation of various influencing factors and the factors of haze formation mechanism were simulated and drawn in Shijiazhuang city.The results showed that the spatial and temporal distribution of haze,seasonal variation characteristics of haze,and the relationship between haze and terrain,etc.OriginPro8.SR3 was used to analyze the correlation between haze concentration,wind speed data,rainfall data and temperature data.
