按照灾害风险评价的一般框架,定性定量相结合,运用破坏概率、滑坡强度、承灾因子、遭遇特征与易损程度等5项指标,尝试提出单体滑坡灾害风险简易评价模型,并结合防治规划,提出了滑坡灾害风险管理对策建议。采用云南新平县滑坡灾害调查数据,开展了实例校验,结果表明,该模型基本反映了滑坡灾害的相对风险水平,可为现阶段管理提供更加明确的分级依据。同时,以期抛砖引玉,讨论险情调查与风险调查之间的关系。
In accordance with the general framework of disaster risk assessment and qualitative and quantitative analysis, the author uses the five indicators of probability of failure, landslide intensity, disaster-bearing factor, characteristics of encounter and vulnerability to make a simple evaluation model for hazard of landslide hazard. Combining with the prevention and control plan , Proposed the landslide disaster risk management countermeasure suggestion. Based on the survey data of landslide disaster in Xinping County, Yunnan Province, an example verification is carried out. The results show that the model basically reflects the relative risk level of landslide hazard and can provide a clearer grading basis for management at this stage. At the same time, with a view to start a discussion on the relationship between risk investigation and risk investigation.
