九寨沟地质灾害预测的空间分析模型

Spatial analysis model for the forecast of geological disasters in Jiuzhaigou

九寨沟是世界自然遗产,由于其活跃的新构造背景条件,因此是地质灾害的高发区。此次研究,应用了地理信息系统的空间分析工具,提取模型因子,采用模糊综合评价方法,建立九寨沟地区的地质灾害预测空间分析模型,划分地质灾害等级,对九寨沟地区的灾害进行预测,取得较好的效果。

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.
