ZHU Wei,MA Jin-song(Geography and Ocean College of Nanjing University,Nanjing 210093,China)  
This paper presents a new method to speed up the processing of spatial neighborhood relation by creating and using neighborhood index.Then the methods of creating,up dating and using the neighborhood index are put forward.At last we analyze the difference of neighborhood relation processing speed between with and without neighborhood index.The paper concludes that by using neighborhood index the efficiency of neighborhood relation processing can be improved greatly,experimentally and analytically.
