| Abstract: | Jiuzhaigou is a world natural heritage.Because it occurred in an active neotectonic setting,it is an area where geological disasters take place frequently.In this research,the authors applied the GIS spatial analysis,abstracted model factors and used the integrated fuzzy evaluation method to establish a spatial analysis model for the forecast of geological disasters in the Jiuzhaigou area and grade the geological disasters in the area.The forecast for the disasters of the Jiuzhaigou area has yielded good results. |
