基于高精度DEM,采用滑动窗口技术,计算丹巴地区的地貌分形特征。结果表明:地质构造决定地貌的宏观格架,构造规模和期次与地貌的平均分维值和标准差呈正相关关系;地层岩性决定地貌的中观和微观布局,变质作用与平均分维值和最大分维值呈正相关关系;地貌维度的极大值区多为地质环境异常区。该项研究对山地本体认知、地质环境调查及评价具有重要的参考价值。
Based on high resolution DEM and sliding window technology, landform fractal dimension features of the Danba Area were calculated,the result shows that: geological structure determines the macro-scale framework of geomorphology, the scale and stages of geological structure is positively correlated with the average fractal dimension value and standard deviation; stra- tum and lithology determines meso-scale layout and micro-scale layout of the landscape, metamorphism is positively correlated with the average fractal dimension value and maximum fractal dimension value; maximum area of landforms dimension is mostly abnormal areas of the geological environment. This study is of great value to Mountain Ontology awareness, geological environ- ment survey and evaluation.
