STUDY ON THE GEORISK MIS OF HIGH SLOPES AT MOUNTAINOUS REGION CITIES

The occurrence of Geotechnical catastrophe caused by high slope has haltered the economic development of mountain cities. A risk management information system based on the GIS is established by integrating the high slope risk evaluation model of mountainous cities with the graphic processing and the spatial analysis function of the GIS. The system is composed of database module, editing module, analyses module, query and display module as well as webgis module. On the basis of collection, storing, searching, and management for the relevant information, the system can perform the regional assessment and vulnerability assessment of geotechnical high slope risk.
