一、知识解读地表形态对交通运输的影响,特别是对陆地交通运输线路及交通线网密度的影响是很明显的。地形地貌的类型、成因、特征及其发展过程,地形地貌与岩性、构造等地质条件的关系,对路线选择和路基工程有重要的影响。需要说明的是,在科学技术水平比较低的时代,自然因素的作用往往是最重要的,有些自然条件比较恶劣的地区,尽管经济发展要求大力发展交通运输,但有许多不可逾越的自然障碍。在科技高度发达的今天,自然条件影响的比重逐渐下降,社会经济因素成为主要因素。
First, the impact of knowledge interpretation on the surface shape of the transportation, especially on the impact of land transport routes and traffic network density is very obvious. The type, formation, characteristics and development process of topography and landforms, and the relationship between topography and landforms and geology and structure, and other geological conditions, have important implications for route selection and subgrade engineering. It should be noted that in the era of relatively low level of science and technology, the role of natural factors is often the most important. In some areas with relatively harsh natural conditions, although economic development requires the development of transportation, there are many natural obstacles that cannot be surpassed. In today’s highly developed science and technology, the proportion of natural conditions has gradually declined, and socio-economic factors have become the main factors.
