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 thi...
