GIS在描述某城区大气二氧化硫分布中的应用初探
The preliminary exploring of application of GIS on the description of distribution of sulfur dioxide in some city zone
【摘要】 应用地理信息系统(GIS)技术对1996年重庆市主城区大气二氧化硫分布进行了描述和分析.采用GIS的空间分析方法泰森多边形分析和区域插值对大气环境监测数据进行分析处理,避免了以点代面的缺陷,使大气污染物分布描述更为合理.
【Abstract】 The geographic information systems (GIS) technology is applied to describe and analyze the distribution of sulfur dioxide in Chongqing main city zone on 1996. The spatial analysis methods Thiesscn Polygon and Area Interpolation are used to deal with atmospheric monitoring data, which avoid the drawback of points replacing surfaces and make the description of distribution of atmospheric pollution more reasonable.
