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 software 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 analysis.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.
