| 摘 要： | 文章介绍航空遥感确定泥石流沟危险度的评判方法和对铁路威胁程度等级分类标准以及发育程度分区原则。提出评判因素各类标准的影像标志。将影响泥石流向形成、发展的因素归纳为10项指标,分别打分,按总分高低综合评判泥石流沟的危险程度。泥石流沟发育程度分区,主要取决于地形地貌、地质条件的组合。文中列举了应用实例。

| Abstract: | This paper presents that the estimation processes of the dangerous degree of debris flow gulleies determined by the aerial remote sensing, the classified criteria of dangerous degree against the railway and the zoning principles of developmantal degree. The estimation factors are proposed for the image indices of each criterion, which would affect the formation of debris flow gulleies.The developmental factors are concluded into ten indices,marking the points respectively. According to the sum of marking points, the dangerous degree of debris flow gulleies are estimated synthetically. The developmental degree zoning of debris flow gulleies is basically dependent upon the combination of topography, geomorphology and geological conditions. Examples of application are shown. |
