汶川8.0级地震灾区滑坡风险评估方法
Landslides Risk Assessment Method of Wenchuan M8.0 Earthquake Region
摘要
Abstract
We adopt the assessment method based on the three factors of landslide risk as risk zonation,risk probability and risk loss to evaluate the landslides risk of Wenchuan earthquake meizoseismal area,which including 10 counties with the whole area of 26 000 km2 .Results show that although the higher risk region covers 9.03% ar-ea of the total,it makes 42% contribution to landslide occurrence probability and risk loss.The high risk region covers 14.61% area of the total and makes 42% contribution to landslide.The moderate risk region covers 22.28% area of the total and makes 19% contribution to landslide.The low risk region covers 37.93% area of the total and makes 11% contribution to landslide.The safe region covers 16.15% area of the total and makes 3%contribution to landslide.As results of effective prevention measures,the risk of landslide is reduced significantly after earthquake.关键词
