We have presented in the paper the design scheme and planning of the space prediction system for slope geological hazard GIS based based on the characteristics of GIS and slope geological hazard prediction,and established the GIS based system of the space prediction system for slope geological hazard,which consisted of four sub systems with different functions.At the same time we have put forward the space data information standard and the evaluation index system for regional slope hazard prediction of the system, and discussed the model foundation, space scale and method of slope hazard evaluation and dynamic monitoring prediction. Taking MAPGIS as the secondary development platform, with the object oriented development advantage language,we have developed the professional program for spatial information management and slope hazard prediction,emphaszing the development of the models of single slope stability and slope region stability evaluation and attribution and graph database. The system thus developed has combined tightly the slope engineering information database with the graph database and method database, put the regional slope hazard evaluation and the single slope stability evaluation together.It can not only be applied to the slope hazard macrodecision-making, but also can supply the necessary information for single slope hazard control.It is characterized by better visibility, good transmission and copy function and information processability.which may allow us to take full advantage of the data, shorten the simulating and evaluating periods, and reduce cost. Furthermore the visibility of the result can improve the management and decision quality, supply the clipper service for landslide improvement and city plans.
