Tumen City is a geological hazards-prone area,with intensive,susceptibility,mass and repeatability characteristics. The geological hazards not only pose a threat to the safety of the local people's life and property,but also restrict the sustainable development of the local social and economic. Using the SPOT-5 satellite images of 2005,GF-2 satellite images of 2015 as data sources,the paper selected seven assessment factors-topography,the types of the rock and the soil,the density of the geological hazards,geological fault,forest coverage,rainfall amount and annual engineering activities,apply the method of grid analysis to achieve the each factor quantitative classification diagram. Though the raster calculation function of Arc GIS,we overlay each factor which is weighted by weight value to create the hazard index maps,and finally generate the geological hazard risk zoning map of Tumen Area by the re-classification of surfer 11. The results show that,the level of Tumen area's geological hazard mainly is mild and slight,the serious and moderate area mainly concentrate on the important transportation routes and residents living area. Therefore,the government should strengthen the work of the geological hazards monitoring and investigation on the serious and moderate risk areas.
