山地城市高边坡所引起的岩土灾变已经成为制约其发展的一个重要因素。该文将山地城市高边坡灾害风险评价模型与GIS技术先进的图形处理和空间分析功能相结合,建立基于GIS的山地城市高边坡风险管理信息系统。系统由数据库模块、编辑模块、分析模块、查询显示模块以及WEBGIS模块五大模块构成。系统在对相关信息进行采集、存贮、检索和管理的基础上,实现区域岩土高边坡危险性、易损性评价,并得到高边坡风险性分析结果。
The rock-soil catastrophe caused by the high slope of mountainous city has become an important factor restricting its development. In this paper, a high slope risk management information system based on GIS in mountainous cities is established by combining the advanced risk assessment model of mountain slope with the advanced graphic processing and spatial analysis of GIS technology. The system consists of five modules: database module, editing module, analysis module, query display module and WEBGIS module. Based on the collection, storage, retrieval and management of relevant information, the system realizes the risk assessment and vulnerability assessment of the high rock and soil slope in the area and obtains the risk analysis result of the high slope.
