空间分析技术与地理信息系统的结合*

空间分析和地理信息系统是两种有效的空间信息分析和处理技术,二者的结合一方面可以大大拓展GIS的空间分析功能,另一方面也可使得迅速发展的空间分析得到GIS的有力支持,文中对此进行了探讨,并分析了二者结合的途径。

THE COMBINATION OF SPATIAL ANALYSISTECHNIQUE AND GIS

Spatial analysis and GIS are both useful tools for spatial information analysis. Under the supporting of computer , remote sensing and other techniques , they have been widely used in the study of social , economic and natural phenomena . The combination of them can offer users with very useful tools in dealing with spatial data. On the one hand , the combination of them can widen the spatial analysis function of GIS , obtaining more useful information from original data. On the other hand , spatial analysis can get strong support from GIS since they are both dealing with spatial data. However , the combination of these two techniques is not quite popular in soft- ware market and application fields . More efforts should be made in finding ways to solving this problem. In this paper , the autho discussed the potential of the combination of spatial analysis and GIS , as well as the way of the combination. As pointed in this paper , spatial analysis can offers GIS with strong ability , like spatial structure analysis , spatial autocorrelation analysis , kriging analysis , spatial simulation , etc. At the same time , GIS can help in determining the sampling manner and obtaining large amount of data which are. needed in theoretical study of spatial analy- sis. GIS is also quite powerful in presenting the analytical results of spatial analysis. The combination of GIS and spatial analysis can be performed in two ways : The first is adding a data exchange interface between GIS and spatial analysis software. The second way is adding the spatial analysis module into GIS software packages. Considering the current situation of software market , the combination of these two techniques should be developed step by step.
