Based on the project of "Geological Hazard Investigation and Special Research of Zhenba County in the Middle River of Hanjiang River", and combined with regional geological environment overview, remote sensing interpretation and fieldwork, the development regularity of geological hazards in Zhenba County were studied. According to the results, there are nine conditioning evaluation factors: slope height, slope, slope shape, rainfall, engineering geological rock group, distance from fault, distance from river, human engineering activity and disaster point density, which were extracted. Then the judgment matrix of conditioning factors and factor classes were conducted by analytic hierarchy process method,and geological hazard index was built. Finally the geological hazard of Zhenba County was assessed and the risk of geological hazard map was classified. The results are as follows: (1) the main types of geological disasters in Zhenba County are landslides, collapses, and debris flows, including 93 landslides, 6 collapses, and 4 debris flows;(2) Geological disasters are mostly developed in concave-convex slopes, slopes with angles of 0°~10°, slopes with undulations of 0~30 m, and are concentrated in low mountains with elevations of 500~800 m on both sides of the valley;(3) The risk of geological hazard map can be classified into three classes, including high, moderate, and low, with an area of 62.05 km², 143.43 km² and 224.57 km² respectively. High-risk areas are mainly distributed in the Jingyang River Basin, accounting for 14.4% of the total area.
