基于GIS技术的地质灾害风险调查研究

滑坡、泥石流和崩塌是最常见的地质灾害,其严重威胁着基础设施的建设和人类的生命安全。文章以地形、气候、水文、土质、几何特征、结构类型、活动面、位置信息、岩性、走向、倾向、倾角、居民点、道路、桥梁和其他基础设施等影响因素为基础,探究了如何利用ArcGIS空间数据分析方法评价地灾灾害的危险程度;同时提出相应的应对措施,以期提供防治技术和群测群防体系建设等方面的资料。

Landslides,mudslides and collapses are the most common geological disasters,which seriously threaten the construction of infrastructure and the safety of human activities.Based on the influencing factors such as topography,climate,hydrology,soil quality,geometric features,structure type,activity surface,location information,lithology,strike,dip,dip,residential area,roads,bridges and other infrastructure,this paper explores how to use ArcGIS spatial data analysis method to evaluate the risk degree of ground disaster.At the same time,the corresponding countermeasures are put forward in order to provide the data of prevention and control technology and the construction of group detection and control system.
