【摘要】 坡面系统对坡面成土过程和搬运过程有着重要影响,土层厚度在坡面上的空间分布规律能够一定程度上反映坡面过程.该文在区域线路调查的基础上,实地测制武汉市4座典型山地的8条典型坡面,布设36个采样点,并结合遥感影像,调查了其土层厚度的分布特征及坡面系统各要素,结果表明:1)各条坡面总体呈现土层厚度由坡底到坡顶递减的分布规律;2)母质岩性是坡面成土过程所形成土层厚度的主要影响因素;3)坡度和坡长是坡面搬运过程的主要影响因素.更多还原

【Abstract】 The slope system has an important impact on the pedogenic process and transport process of the slope, and the spatial distribution law of the soil layer thickness on slopes can reflect the slope process to some extent. This paper constructed eight typical profiles of four typical mountainous areas in Wuhan and laid 36 sampling points based on the regional route surveys. In addition, with remote sensing images, the distribution characteristics of soil thickness and the various elements of the slope system were investigated. Results showed as follows.1) Generally, the distribution law of soil layer thickness is decreasing from bottom to top of slopes. 2) Parent lithology is the major influencing factor of soil layer thickness formed by the pedogenic process on the slopes. 3) Slope and slope length are the major influencing factor of the transport process on the slopes.更多还原
