| 摘 要： | 滑坡灾害风险评价是一个包含有滑坡危险性评价和承灾体易损性评价的体系,对滑坡危险性进行了空间预测与区划,并开展了区域承灾体易损性的区划与评价。结合风险评价的基本要求,进行了研究区滑坡灾害的风险区划,将其划分为极高、高、中、低与极低风险区。针对研究区经济发展水平及政府防灾力度,提出了适合研究区的可接受风险标准与管理对策。

| Abstract: | Landslide hazards risk evaluation includes landslides hazad evaluation and hazard-affected body vulnerability evaluation.The authors predict and zone the landslide hazards of the region,and zone and evaluate the vulnerability of the hazard-affected body.The hazard risk was divided into five ranks according to the basic request of landslide hazards risk evaluation.They are extreme-high,high,middle,low and extreme low risks.At last,the acceptable risk standard and management strategy in line with the economy ... |
