Abstract
The objective of this paper is to reveal the relationship between the soil moisture content and Hyperspectral.The paper tested 60 sandy soil samples in the south of Gurban tunggut desert with SVC field-portable spectroradiometer and established the liner regression between sandy moisture content and infrared bands which are sensitive to soil moisture content.The results showed that field test spectral of the sandy soil and logarithmic transformed refletance of the sandy soil did not show fine regression with the soil moisture content;the refletance which was continuum-removed and then first derivative regressed well with the soil moisture,the coefficient of determination(R2) was 0.855.This method provides a new idea to retrieve sandy soil moisture which is practicable and operated easily.
