Abstract: Maoxian county is located in the deep valley region of southwest China with severe slope geological hazards, hence is a good experimental base for characteristic research and susceptibility evaluation of geological disasters. In this research, Analytical Hierarchy Process (AHP) was adopted for the evaluation and zoning of geological disaster susceptibility in the study area based on geo-hazard investigation and remote sensing data interpretation. Seven indices inclusive of height, land relieve, slope shape, gradient, lithology, water, and geological structure were selected as evaluation indicators. Result show that the area of high susceptibility covers 46.1 km², accounting for 10.02% and distributing mainly along mainstream Minjiang River and some tributaries; the area of medium susceptibility covers 149.59 km², accounting for 32.52%; and area of low susceptibility is 205.25 km², taking up 44.62%; and the stable area covers 59.06 km², comprising 12. 84%.The results are consistent with field investigation results in general, and thus could be taken as basis for land use planning and slope geo-hazard prevention and reduction in Maoxian county.
