Continuous low-efficiency industrial land change detection method and system based on remote sensing image

The invention relates to the technical field of remote sensing, in particular to a continuous low-efficiency industrial land change detection method and system based on a remote sensing image. Comprising the following steps: acquiring target images collected at different moments for a target land; aiming at each target image, identifying each pixel point corresponding to each land use type in the target image and pixel point information of each pixel point; wherein the land type comprises a constructed type, a bare land type and an unplanned type; the pixel point information comprises the number of pixel points and the positions of the pixel points; combining the pixel points of the bare land type in the target image to obtain at least one developable bare land cluster; determining the bare land use value of each bare land cluster in the target image according to the pixel point information of each land use type in each bare land cluster; and determining the land use evolution rate of the target land use acco
