近年来,频繁发生的泥石流灾害给中国部分地区造成了巨大的破坏。泥石流点多面广、成灾迅速,难以对其进行准确的监测预报,风险评估就显得尤为重要。本文从泥石流灾害风险的构成要素、危险性评估研究和承灾体脆弱程度评估研究等方面分析了泥石流灾害风险的研究现状。从当前的研究现状中可以发现:灾害风险公式得到广大学者普遍认同,泥石流危险性评估方法也相对比较成熟;但在泥石流灾害对承灾体的致损风险机理分析方面研究尚需深入,危险性评估中如何实现从点评价向面评价过渡还需进一步探讨,对承灾体脆弱性研究也需要引起重视。因此,在今后的评估研究中,需要加强这些方面的研究探索,进一步提高泥石流灾害风险评估结果的可信度,提高其实用性。
In recent years, frequent landslides have caused tremendous damage to parts of China. Debris flow point wide, rapid disaster, it is difficult to accurately monitor the forecast, the risk assessment is particularly important. In this paper, the research status of debris flow hazard risk is analyzed from the aspects of risk factors of debris flow, risk assessment and risk assessment. From the current research status, it can be found that the formula of disaster risk is universally accepted by most scholars and the risk assessment method of debris flow is relatively mature. However, the research on risk mechanism analysis of damage caused by debris flow disaster still needs further study. How to realize the transition from the point evaluation to the surface evaluation in the assessment needs to be further explored, and the research on the vulnerability of the disaster-bearing body needs to pay more attention. Therefore, in the future assessment studies, we need to strengthen research and exploration in these areas to further enhance the credibility of the debris flow risk assessment results and enhance their practicality.
