Basic Studies on the Extraction of Soil and Vegetation Informations of a Basin Using Remote sensing

Abstract

This paper discusses the characteristics of soil reflectance under many different soil moisture ratios and vegetation cover rates, and the influence of vegetation vitality on its reflectance. A very close correlation between soil reflectance at a wavelength of 650nm and that at a wavelength of 800nm is revealed. The vegetation cover rate is formulated in terms of soil and vegetation reflectance at wavelengths of 650nm and 800nm. The vegetation reflectance is strongly influenced by its vitality, which is related to the moisture content and chlorophyll-a concentration in the vegetation.
