将四川省农村地区分成平原和浅丘区、小起伏山地和高丘区、高山峡谷区三种类型区域。利用GIS软件，将四川省划分网格，分别统计每个网格中的工业废气污染点源数量和主要交通线路长度，得出四川省工业废气污染点源密度分级图和四川省主要公路密度分布图，以及结合农村污染面源的情况分析，总结出农村区域的主要污染密度分布类型。结果表明，在一定区域范围内，农村平原和浅丘区的工业源、交通源、农村面源分布均匀；高丘区、小起伏山区、高山峡谷区的污染源分布均具有明显的地理分布特性，山间平地和山谷台地的污染源分布密度高；根据四川省污染源分布规律给农村空气自动监测布点提供了指导。

The rural area of Sichuan province was classified into three types as plain and shallow hill region, small ups and downs mountains and high hill region and alpine valley region. By meshing the map of Sichuan province using the software GIS and conducting statistic of the point pollution source number of industrial waste gas and the length of main traffic lines in every mesh, the grading map of point pollution sources of industrial waste gas and high way density distribution map in Sichuan province was obtained. Considering the analysis of non-point pollution sources, the distribution type of main pollution densities in rural area was concluded. The research results showed that in certain regions, the pollution sources from industry, traffic and rural area distributed uniformly in plains and shallow hill region. They distributed geographically in high hill region, small ups and downs mountains and alpine valley region. The high density pollution sources distributed in mountain plains and valley platforms. The achievements provide a guide for automatic air monitoring points setting in rural areas of Sichuan Province.
