THREE PRINCIPAL FACTORS FOR INTEGRATIVE ASSESSMENT OF REGIONAL LANDSLIDE RISKS

  • 摘要: 区域滑坡风险综合评估应该包括三方面要素,即:滑坡区域风险分布 滑坡风险概率、滑坡风险损失。作者在滑坡风险区划的基础上,查明风险分布的状况,评估风险影响的地区范围。根据滑坡的诱发因素,分析发育的滑坡特点,评估滑坡发生的概率。采用受灾面积占评估区域的损失率统计,评估可能受灾损失的规模。将三要素评估迭加, 建立了滑坡风险综合评估模型。并将此模型在四川省攀枝花市米易县进行了示范研究,最后得到米易县全县滑坡风险中等偏低的结论,这与研究区的实际情况基本一致,取得了较好的应用效果。
