摘要
本文应用分数维几何学的方法,对滇西北区断裂系进行解析并确立了各断裂系的地位;从该区各典型子区活动断裂与水系的几何学分析和对比,探讨了二者的分布特征及其相关性。
Using a fractal geometry analysis, the fault systems in northwestern Yunnan were interpreted and their geometrical standings were determined. The fractal characteristics of active fault systems are described by a comparison of the fault and river systems in several subareas. The result shows that 1) NE-trending fault system (D=1.32) is more complicated in geometry than those in NW(D=1.26) or SN (D=1.32) directions, indicating that NE-and NW-trending fault systems are at least equal in status in this region, and 2) the difference -in fractal dimension between active fault and river system increases from south to north, indicating that the distribution of river system is more strongly controlled by strike-slip fault than oblique-slip fault.
