Risk evalution of geological hazard based on RS and GIS in Changdu county of Tibet
摘要
Abstract
Based on detailed investigation of geological hazards in Changdu county,Tibet, geological hazards symbol is established by using ETM+ and IKONOS remote-sensing data then interpretation is conducted and main influence factors for geo-hazard fatalness are analyzed statistically and the risk is evaluated by using Analytic Hierarchy Process and GIS method and finally is completed the risk assessment zoning map with high-risk area accounting for 0.42％; dangerous area 3.43％; low-risk 18.56 ％; non-hazardous area 77.59％. There are three major geological hazard types, namely landslide, collapse, debris-flow in Changdu county. In total 205 potential hazardous points occur of which 33 are in large size imposing certain threat to the people's life and property.关键词
