Abstract：In order to evaluate and map the susceptibility of geological disaster of Shenzhen's slope,to master the distribution and influence factors of geological disasters in Shenzhen,it is adopted the combination of qualitative and quantitative methods.Based on GIS and RS,spatial query,buffer analysis,overlay analysis and statistical analysis are used to the influence factors of geological disasters,the result shows that the relationship between geological disasters and infecting factors (slope,rock group,distance from the water system,distance from the fault and vegetation coverage) are close.And the weight of the impact factor of the geological disaster is calculated using the analytic hierarchy process,to assign the calculation result of the weight value to the data layer of the grid influence factor,and divide the slope disaster in Shenzhen into four grades using the GIS spatial analysis function:high prone area,middle prone area,low prone area and no prone area.The results shows that this method can improves the efficiency of analysis,and change the traditional evaluation mode,and reduce the cost.
