| 摘 要： | 滑坡空间分布的定量研究对了解滑坡的发育特征具有实际意义，能够为滑坡的防治提供重要依据.为了了解滑坡的空间分布特征，以江西省宁都县1：5万地质灾害调查数据为基础，基于ArcGIS空间分析叠加模块，对滑坡空间分布规律应用变维分形理论进行定量研究，揭示出滑坡空间分布与地形地貌、岩土体类型、高程、坡度均呈二价累计和分形分布，使得滑坡与各因素之间的关系从定性分析上升到定量研究，并计算出分维值，说明了分维值的意义.

| Abstract: | The quantitative study on the spatial distribution of landslides is of practical significance to understand their development characteristics, and can provide important basis for landslide prevention. To find out the spatial distribution characteristics, the variable dimension fractal theory is applied to carry out a quantitative study on the spatial distribution regularity based on ArcGIS and the data of 1:50000 scale geological hazard survey in Ningdu County of Jiangxi Province. The results show that the spatial distribution of landslide is in second-order cumulative total fractal distribution to landform, rock-soil mass type, elevation and slope, promoting the study from qualitative up to quantitative level. The fractal dimension values are then calculated with explanation for the significances. |
