| 摘 要： | 喀斯特地貌的形态分析对喀斯特发育程度的理论研究、人类工程活动等具有重要指导意义.采用分形方法对云贵高原南东部丘北区的峰丛洼地的形态特征进行分析,结果表明,(1)多边形洼地的空间排列为随机至簇状分布,干巴地以北洼地成簇状分布,其余地区为随机分布,部分洼地沿断层发育,面积较大.(2)洼地形态分布具有明显的分形特征,有两个标...

| Abstract: | The morphological characteristics of karst landform are of important guiding significance in the theoretical study of the karst development and in human engineering activities.This paper analyses the peak-cluster depressions of 40 km2 in southeast Yungui Plateau based on the fractal theory.The results show that the(1) depressions develop randomly or like cluster,some depressions form along faults and become larger,(2)Depression distribution shows apparent fractal characteristics;there are two scale ranges w... |
