Abstract

The results of this study are summarized as follows: (1) Differences in electric magnetic reflectivity patterns of soil formed by various kinds of vegetation were explained by root distribution condition and the water content condition of the formed soil. (2) It was verified from the vertical distributions of softness of forest soil and luminance values obtained from the electric magnetic reflectivity profile, that the depth at which the luminance value decreases in shallow subsurface can interpreted as the lower limit of depth of the effective soil layer. (3) A satisfactory negative correlation was found between the water content by volume and the luminance value, which is an electric magnetic reflectivity.
