The invention discloses a remote sensing image fusion method, system and device based on exponential scaling transformation and a medium. The method comprises the following steps: acquiring a satellite remote sensing image with a near-infrared band, a red band, a green band and a blue band; fusing the near-infrared wave band with one or more of other wave bands, taking the fused wave band or wave band combination as a numerator, taking the corresponding wave band or wave band combination before fusion as a denominator, and calculating a characteristic ratio index; constructing an exponential scaling transformation function according to the characteristic ratio index and the characteristic threshold thereof; according to the exponential scaling transformation function, an enhancement coefficient function of vegetation feature enhancement is constructed; and synthesizing a wave band obtained by respectively enhancing the red wave band and the green wave band by using the enhancement coefficient function and an
