灾后景区建设场址安全性分析
Post-Disaster Safety Analysis of Construction Site of Scenic Region
摘要
Abstract
A 3D virtual model for high gradient zones and flow path regions was built by quantitative analysis methods of the digital elevation model,to guide the safety monitoring and ecological restoration of a regional environment after disaster.Using the virtual model,the site environment in the geological disaster region of Shenxigou was analyzed with a landscape scale of 5 000 unitary granularity.The result shows that the relevant influencing factors that can trigger disasters include slope and confluence cumulant,and regions with a slope of greater than 50° and a large ecological environment change are susceptible to mud-rock flow and other geological disasters.Combination of the cumulant outlet diagram with the hazard maps for mud-rock flow shows that many sites of geological hazards are in the water outlet area or along the flow path.Therefore,the security monitoring and ecological restoration of sensitive slope areas should be strengthened after disasters.In addition,the soil reinforcement and vegetation planning for geological disaster regions and the land utilization adjustment planning for landscape ecological security were proposed.关键词
