空间分析是GIS的核心内容，已成为选择GIS软件的重要指标之一。针对目前广大用户对GIS需求从简单的查询、量算过渡到复杂的地理分析与计算，亟需明确认识现有GIS软件空间的分析功能。本文在详细介绍空间分析的概念、发展与应用以及空间分析类型的基础上，对ArcGIS、ArcView、MGE、MapInfo、MapGIS以及Su-perMap等国内外主流GIS软件的空间分析功能进行了详细的比较。结果表明，国内外GIS软件在查询与量算、缓冲区分析、空间叠加分析、栅格数据分析等最基本的空间分析功能方面基本相当，而在网络分析、空间统计分析、三维分析、二次开发能力方面，存在差异。其中，国内GIS软件空间分析功能正逐步完善，甚至与国外知名GIS软件相当。%Geographic Information System(GIS)comes into analysis stage from database stage with the development of GIS theory and computer technology,and the function of GIS software is progressively expanding and improving as well. As the core content of GIS,spatial analysis has become an important indicator to choose GIS software. According to the demand of the users for GIS,it has gradually changed from the simple query and measurement to the complex geographic analysis and calculation. Therefore it is urgent to have a clear idea of spatial analysis function of existing GIS software. This paper firstly makes a comprehensive introduction of the concept,development,application as well as classification of spatial analysis. Furthermore,a detailed comparison of the spatial analysis function is carried out between domestic and overseas GIS soft,such as ArcGIS,ArcView,MGE,MapInfo,MapGIS and SuperMap. The result shows that domestic GIS platform is roughly equivalent to foreign well-known GIS software in spatial analysis function. The function of all these GIS software are basically the same in terms of spatial query and measurement,buffer analysis,overlay analysis,raster da-ta analysis,etc. However,when it comes to the function of network analysis,spatial statistical analysis and three-dimen-sional analysis,these GIS software performs quite differently. This article expects to provide a targeted reference for users to select the appropriate GIS software in practical work.
