The invention discloses a remote sensing image fusion method and system based on a vegetation coverage characteristic power function and a medium, and the method comprises the steps: calculating a characteristic ratio index according to an obtained satellite remote sensing image with a near-infrared band, a red band, a green band and a blue band; constructing a power function space of the vegetation coverage according to the characteristic ratio index; the value of the power function space at the feature threshold value of the feature ratio index is made to be a determined value, and the vegetation coverage feature power is determined; a corresponding enhancement coefficient function is obtained according to the determined vegetation coverage characteristic power and the power function space, and then the red wave band and the green wave band are enhanced; and synthesizing the enhanced red wave band, the enhanced green wave band and the original blue wave band to obtain a true color image vegetation feature e
