摘要
空间分析是GIS区别于一般信息系统的主要特征,在土地定级中发挥了重要的作用。文中着重论述了GIS空间分析在土地定级中几个关键问题的应用,如:空间查询、叠置分析、缓冲区分析、空间统计分析等,结合定级实例来说明其在土地定级中的应用。
The spatial analysis is major characteristics of the GIS different from normal information system,which plays important role in determination of the land grade.In the paper,the application of the GIS spatial analysis in determining some key problems of the land grade is highly discussed,such as spatial query,superposition analysis,buffer zone analysis and spatial statistic analysis etc.,and actual practice in this respect to illustrate its use in determination of the land grade is particularly given as well.
