Abstract: Geohazards are frequently occurred in the mountain areas of western part of the country. This paper presents the pilot study results on the Yinjiang County of Guizhou Province.  Both the geological hazard inducing factors, such as, ground elevation, grade and direction of the target slope, lithology and the tectonic structures and the environmental hazard inducing factors, such as, annual precipitation and highway engineering, are used in the evaluation by the Arc GIS with information method. The results indicate that areas with high geohazard risk and extremely high geohazard risk in Yinjiang County account for 27.33% and 5.40% of total area, respectively. These areas are mainly distributed in northwestern and southwestern of Yinjiang County. Areas with extremely high geohazard risks are mainly distributed in Eling Town, the south of Banxi Town, Shanshu Village and Zhongba Village.
