Paper Abstract

This paper introduces a new amendment dielectric model in the microwave band concerning the principle of soil science which can also give the information about soil texture and variety of soluble salt ions, and points out some errors of original model at the same time. The new model is confirmed suitable for saline soil with different levels of moisture and salinity soil samples prepared in lab. Based on the research on the dielectric properties of saline and alkali soils, this paper also brings forward the feasibility of separating them. Contrasts to the classic dielectric models of soil, all the parameters of the improved model have their physical meanings, and the procedures avoid neglecting principle of soil science and optimization blindly. So the parameters can give us more information about moist saline soil. This study sums up dielectric properties of moist soil, and adds salt-affected factor. Thus we can describe dielectric behavior of moist saline soil more precisely. In further research it pays attention to the relationship between dielectric properties and backscattering coefficients or polarimetric information extracted from radar image.
