基于GIS的大气污染源排放清单空间分配研究——以贵州省黔东南州为例

Research on Spatial Distribution of Air Pollution Source Emission Inventory Based on GIS—Taking Qiandongnan Prefecture in Guizhou Province as an Example

为建立贵州省高空间分辨率大气污染源排放清单提供技术依据,以黔东南州现有大气污染源排放清单为基础,采用GIS技术开展了3 km×3 km空间分配方法研究。结果表明:黔东南州各市(县)排放的污染物分布不均衡,与人类活动区域基本呈一致分布。不同污染物在不同市(县)单位面积排放量、总排放量的排序不同,凯里市最大。

To provide a technical basis for establishing a high spatial resolution air pollution emission inventory in Guizhou Province,a research on the 3 km×3 km spatial distribution method was carried out using GIS technology based on the existing air pollution emission inventory in Qiandongnan Prefecture.The results show that the distribution of pollutants emitted by cities(counties)in Qiandongnan Prefecture is uneven,and the distribution is basically consistent with the human activities.Different pollutants in different cities(counties)have different rankings per unit area and total emissions,with Kaili City being the largest.
