- Abstract:
-
Through analyzing the correlation coefficient, standard deviation and diagnosis index of the former nine bands in Aster remote sensing image, it finds that the soil reflectivity of b1, b2, b3 in Aster remote sensing image is more sensitive to salt content in the soil. Stepwise regression analysis is made by using the b1, b2, b3 in Aster remote sensing image as independent variable and salinity in soil as dependent variable, and the statistical model of the soil reflectivity data and the soil salt content data is established. The surface object is divided into five kinds by using decision tree sort, in order to obtain the spatial distribution map of salinity in saline-alkali soil. The research indicates that the effect of remote sensing reversion based on statistical model is better and the research result has a certain value of reference and application.
