| 摘 要： | 崩塌地质灾害的致灾体具有隐蔽性特征,传统的调查手段难以查明所有的致灾体,而隐蔽性致灾体一旦失稳破坏,往往造成群死群伤的灾难事故.因此,如何提早识别与预防灾难的发生,成为地质灾害防治学者专家关注的焦点.以凯里市龙场镇崩塌灾害为例,运用GIS技术,采用风险评估的方法,对影响崩塌灾害发生的各因素进行叠加综合,从而分析出灾害的易发性、危险性和易损性,得到灾害的风险性,从而为灾害的预防提供参考与指导.

| Abstract: | Disaster-causing body of rockfall hazard has the characteristics of concealment, it＇ s difficult to find out all of disaster-causing body with traditional researching method. Once destroyed, it often cause mass death and casualty. Therefore, how to identify and prevent the happening of the disaster early, has become the focus of scholars and experts in geological hazard prevention and treatment. Take the rockfall hazard happened at Longchang Town in Kaili city for example, using GIS technology and the method of risk evaluation, super- posing all the factors that affecting the rockfall hazard, to analyze the possibility, dangerousness and vulnera- bility of the hazard, and obtained the results of hazard risk evaluation. It provide reference and guidance for the prevention of hazard. |
