The invention provides an inversion method and device for vegetation coverage of hyperspectral remote sensing image data, and relates to the technical field of hyperspectral remote sensing image processing, and the method comprises the steps: obtaining hyperspectral remote sensing data and corresponding high-resolution remote sensing data in a target region at the same time period; extracting and identifying pure end members contained in the hyperspectral remote sensing data, and determining at least one type of pure end members; obtaining a pure end member category, a pure end member area and a pure end member area proportion contained in a mixed pixel in the hyperspectral remote sensing data by combining the high-resolution remote sensing data; and training the initial mixed pixel unmixing model to obtain a target mixed pixel unmixing model so as to invert the vegetation coverage in the to-be-monitored area. According to the invention, the unmixing of the mixed pixels in the hyperspectral remote sensing ima
