| 摘 要： | 通过对地理地貌形态分类方法的研究,结合公路工程的特点,提出公路地貌形态分类的要素为相对高程、地面坡度和地面破碎程度。根据区划指标体系建立的原则和方法,以大地构造、地面自然坡度和相对高程作为公路地貌一级区划的主导指标;以外力地质作用、困难度指数和地表切割密度作为公路地貌二级区划的主导指标;以海拔高程作为各级区划的辅助指标,建立了中国公路地貌区划指标体系。利用地理信息系统(GIS)将中国分为5个公路地貌一级区,分区结果与实际情况基本相符。 |

| Abstract: | The relative elevation,slope and fragmentation degrees of earth's surface were put forward as the main classification factors of highway topographic based on the study of geography topographic classification and the characteristics of highway.According to the principles and methods of index system establishing,tectonic,slope and relative elevation were selected as the leading index of first-order regionalization,the external geological action,difficulty index and cutting density of earth's surface were chos... |
