Landslide Risk Assessment Research On Jiasa

Geological disaster assessment is one of an important research direction in the field of geological engineering. Geological disasters to the people’s life safety risks, but also to the state and people’s property caused huge losses. Especially the landslide disaster, is second only to earthquake and flood serious geological disasters, the frequency of occurrence of large. Landslide risk assessment involves natural science theory, and relates to the social economy theory, it is a comprehensive study. Landslide risk assessment includes both the content of risk evaluation of the damage caused by disasters and the content of risk analysis in risk assessment and risk zoning and estimates, is a complete assessment system. The detailed study of landslide hazard assessment, socio-economic vulnerability assessment, landslide risk assessment and other content.First analysis of landslide risk assessment at home and abroad, research content. Summary of the risk assessment and risk management knowledge framework, clear up regional landslide hazard associated with each concept, differentiate the landslide hazard assessment and the assessment of social economic vulnerability related concepts, discusses regional landslide hazard risk assessment theory and method.According to lance Jiasha of geological environment condition, social economic development status, and established risk assessment system in Jiasha. On landslide disaster influence factor and correlation analysis, the risk assessment of landslide hazard which include the disaster-causing factors and disaster environment risk evaluation and for vulnerability assessment of two aspects.At the end of the study of regional risk assessment.The information model and AHP levels analysis method to carry on the hazard evaluation, the contribution of weighting method for vulnerability evaluation, completed a series of landslide risk assessment research.the Jiasha a total area of about368square kilometers area conducted a comprehensive risk assessment, considering the natural and economic factors and other aspects of the problem, using GIS software to generate risk zoning map,providing more certain certain reference for to regional landslide hazard assessment, prediction and prevention.
