The Study On Suitablity Assessment Based On Geological Hazards Risk For Construction In Mountainous Vilages

Geological disasters are one of the most threatening natural disasters to humanity on a global scale.The villages and towns distributed in the mountain areas have always been high-risk areas for geological disasters such as collapses,landslides,and mudslides,and the development of villages and towns themselves has caused the destruction of disasters to be enormous.Nowadays,that some mountain villages appeared to ignore potential risks of geological disasters,the development of the reckless and disorderly conduct;barbarian expansion of this city like,can easily disrupt the fragile geological environment sensitive mountain areas,induce geological disasters,increase disaster in mountain villages and towns.Therefore,based on the risk of geological disasters,the evaluation of the suitability of land for regional construction are the key points for promoting the sustainable development of mountainous villages and towns.In this study,the National Technology Support Program "Rural Area Comprehensive Disaster Prevention and Mitigation information systems research and demonstration"(2014BAL05B07)project-based,project demonstration area-Shennongjia forest areas as the study area,Study on Suitability Assessment of Construction Land for Mountain Villages Based on Risk of Geological Disasters.First,a mechanism based on geological disaster geological disasters mountain villages monomer micro-level analysis of the impact area;secondly,from macro level to explore the correlation between the spatial distribution of geological disasters in mountain villages and causal factors,and comparative analysis of different building regression model,select the best model for regional risk assessment of geological disasters;Finally,a suitability evaluation of the mountain village construction land with different levels of risk of geological disasters as the leading factor,has constructed accuracy,maneuverability and evaluation of promotion Systems and methods,and explore the application of evaluation results in spatial planning of mountain villages and towns.The research methods applied in the case of District GIS,GeoDa and SPSS and other software-based delineate the possible impact of a range of different types of geological disasters in the region monomer,the use of the results of regional geological hazard risk zoning best predictive model SLM obtained was evaluatedThe results show that the evaluation model proposed in this study can be more accurately and effectively evaluate the suitability of land for construction of mountain towns and villages from the area geological disaster risk perspective,the evaluation results can support the regional planning work mountainous villages,towns and villages to assist the development of safe and orderly manner.
