| 摘 要： | 为了对滑坡的空间分布特征进行定量的研究,以香溪河流域高阳—官庄坪段为例,基于变维分形理论对滑坡空间分布的分形模型进行了优化,定量地得到了各影响因子与滑坡空间分布之间的敏感性关系,同时对滑坡空间分布的成因进行了定性分析,结果与利用分形理论得到的定量敏感性关系相一致,表明优化的分形模型具有可靠性。

| Abstract: | In order to make the quantitative research on the characteristics of the spatial distribution of landslides,this paper takes the Gaoyang-Guanzhuangping section of Xiangxi River basin as an example and applies variable dimension fractal theory to the optimization of the fractal model.The paper qualitatively analyses the relationship between the sensitivity of spatial distribution and impact factors,and the cause of the spatial distribution of landslides.The results show the accordance of two methods,indicating that the optimized fractal model is reliable. |
