Abstract: Hyperspectral remote sensing has been widely used in soil moisture inversion because of abundant spectral information. Through summarizing the remote sensing monitoring methods of soil moisture content, the advantages, disadvantages and scope of application of microwave method, thermal infrared method, optical method and hyperspectral remote sensing method were analyzed, the quantitative method of hyperspectral remote sensing was emphatically analyzed, the research process of statistical model and mechanism model were elaborated, radiated transfer model and geometric optics model were described particularly, the research results of soil moisture content based on the mechanism of remote sensing inversion model in recent years were summarized and the existing problems and future research direction were put forward.
