| 摘 要： | 冰川泥石流广泛分布于我国西部地区，特殊的地貌条件对泥石流的发育有着重要影响。地貌信息熵理论是量化地貌发育阶段的指标，针对冰川地貌条件，探讨了地貌信息熵理论在冰川地貌条件下的应用，并提出了相应的修正系数。选取天山公路沿线13条泥石流沟，基于ArcGIS平台，进行了危险性评价。结果表明，修正后的地貌信息熵值能较好地判断冰川泥石流的危险程度。

| Abstract: | Glacial debris flow is widely distributed in western China, where the special landform conditions have significantly impacted the development of glacial debris flow hazards. Geomorphic information entropy theory is applied to quantify the development stages of geomorphology. In this paper, the application of geomorphic information entropy theory to glacial geomorphic condition is discussed and the corresponding correction coefficients under various glacial geomorphic conditions are proposed. Thirteen debris flow gullies along the Tianshan Highway were selected for risk assessment based on the ArcGIS platform. As a result, it is found that the corrected geomorphic information entropy value is able to judge the risk of glacial debris flow. |
