| 摘 要： | 结合三维遥感影像解译提出一种定量的泥石流土石量计算方法。在泥石流汇水区内对地形进行0次谷与1次谷划分,按可搬运的物质总量和一次降雨所能搬运的物质总量两种方式进行分析,使计算结果更加精细化;以数字高程模型(DEM)与降雨所搬运的土石总量作为影响范围模拟的基础,利用GIS空间分析功能分析泥石流汇水区的横截面面积及区域平面面积等地形参数,判别土石产出量与地形参数关系,实现泥石流影响范围的模拟。分析结果可为潜在泥石流危险区域评价预测提供参考。

| Abstract: | A new quantitative calculation method of the earth-rock output of debris flow is presented in this paper.In the area of geological disaster development,the earth-rock output assessment is involved in both the surface loose accumulation and the output of the possible geological hazards,such as collapse and landslide.In the collection area of debris flow,the terrain is divided into 0-time valley and 1-time valley.Two methods are used to analyze the results of the calculation in order to make it more precise.O... |
