| 摘 要： | 定量分析滑坡孕灾环境因素的敏感性有利于研究滑坡的形成机制和空间分布特征。基于变维分形理论,应用累计变换和次数和分维值两个分形指标,对研究区内滑坡与孕灾环境因素的关系进行定量分析,为构建滑坡敏感性分析评价指标体系提供分形学依据。研究表明:植被覆盖、岩土类型和坡度等因素对滑坡发育的影响程度较高,是研究区内滑坡空间分布的主要控制因素;断裂构造和河流两个因素对滑坡发育的影响程度较低,对研究区内滑坡空间分布的控制能力较弱。

| Abstract: | Quantitatively analyzing the susceptibility of disaster-pregnant environmental factors of landslide is beneficial to research on its formation mechanism and space distribution characteristics. Based on variable dimension fractal theory, applying two fractal indices-transformation frequency and fractal dimension, we quantitatively analyzed the relationship between landslide and disaster-pregnant environmental factors to provide the fractal basis for choosing indices to evaluate landslide susceptibility in the study area. Research has shown that factors of NDVI, lithology, slope, etc. effect landslide development more seriously and control the spatial distribution of landslide in the study area; comparatively, factors of fault, river, etc. would less influence landslide development and control its distribution in the study area. |
