Summary: | The invention discloses a method for monitoring the moisture content of surface soil. The method comprises the following steps: acquiring radar images acquired by a radar satellite and spectral images acquired by a multispectral satellite in different soil areas; extracting radar parameters corresponding to the radar image, and extracting spectral parameters corresponding to the spectral image; a plurality of radar characteristic parameters are obtained through construction of the radar parameters corresponding to all the radar images, spectral indexes are obtained through construction of the spectral parameters corresponding to all the spectral images, and the radar characteristic parameters and the spectral indexes are used for representing moisture information of the corresponding soil areas; based on a multiple linear regression algorithm, a BP neural network algorithm and a support vector machine algorithm, the radar characteristic parameters and the spectral indexes of all the soil areas and the moistur |
