【Abstract】 Geological hazards such as landslides, rockfalls and debris flows happen frequently in southwestern China and bring about great damage to peoples′ life and property. Therefore, it is of great significance to develop an evaluation system of geological hazards based on the data from regional geoenvironmental investigations. In this paper, the up-to-dated status in this field is reviewed and a technical path and approach for this purpose based on GIS is discussed, and also a new approach to geoenvironmental evaluation based on GIS is researched.更多还原
