摘要
文章系统地总结和分析了当前比较常用的泥石流危险度评价的研究方法,指出现行泥石流危险度评价中评价因子的提取往往需要详细野外勘查,工作量大、费用高,不便于对众多泥石流沟的普查;并提出一种在现场踏勘基础上,基于泥石流规模、频率和承灾体特征的快速便捷的新方法——泥石流危险度野外快速评价,并结合其他方法进行了实例对比验证。结果表明:泥石流危险度野外快速评价结果可靠,可作为快速评价泥石流危险性的新方法进行推广应用。
Different techniques of debris flow hazard assessment are reviewed. In all these methods, the evaluation factors extraction is a tedious work. The fast debris flow field hazard assessment method which is more convenient and combine the magnitude, frequency and characteristics of object effect of debris flow hazard are presented in this paper and use Examples verification and comparison with other methods. The results of debris flow fast field hazard assessment are consistent with other methods and it can be used as a new approach to application.
