Saline soil cause great damage not only to the agricultural production but also to the ecological environment. The general model for optical spectrum characteristics of the saline soil in Jilin Province was established and validated according to the polarized and hyperspectral spectral information. The results show that there is a strong relationship between the hyperspectral polarized information of saline soil and its physicochemical property parameters, especially for the soil line, from which we could calculate the soil with different of salinity.
