Abstract:
Taking Xiangtang area in the center of Huangshui valley as an example, using spatial analysis functions of GIS,integrated with the factors that affect landslide,such as terrain,vegetation, human activities and so on, and taking grid as the basic assessment unit, the influences of each factor on the relative risk of landslide were observed. And the assessment map of landslide hazard was obtained by overlying each layer which was evaluated by the attribute.This provides a quick method for assessing landslide hazard．
