| 摘 要： | 地貌特征是泥石流灾变过程中的一个重要因子,可通过研究泥石流流域的地貌演化阶段来判定泥石流灾害的发育特征。对此,在对贵州望谟泥石流灾害详细调查的基础上,对其中12条典型泥石流的形成机理和地貌演化阶段进行了对比划分,以此确定了该地区泥石流形成机理所对应的地貌信息熵H的区间。运用此结果可对该地区沟谷型泥石流可能的形成机理进行预先判断,并对危害性较大的泥石流沟采取相应的防治措施,以减小突发性灾害所带来的损失。

Study on Influence of Geomorphic Evolution in Debris Flow Reaches on Mechanism of Debris Flow in Wangmo,Guizhou |
| |
| Abstract: | Geomorphic feature is an important factor in catastrophic process of debris flow, and the geomorphic evolution stage in debris flow reaches may be taken as the criterion to judge the development characteristics of this disaster. Thus, based on the detailed investigation on the debris flow disaster in Wangmo, Guizhou, this paper compared the 12 articles of the typical formation mechanism of debris flow, and divided the geomorphic evolution stages, then hereby specified the intervals of geomorphic information entropy H correspond to the mechanism of debris flow in this area. With this result, the possible mechanism of gully debris flow therein may be decided in advance, thus against the more destructive debris flow, the related prevention and control measures may be taken to reduce the loss caused by the sudden disasters. |
