Summary:The invention discloses a forest change rapid detection method research based on a Gaofen-2 image, belongs to the technical field of forest resource dynamic change monitoring, and aims at obtaining aremote sensing image of a forest resource to be detected in a continuous time period through GF2 multispectrum, taking an original image as a reference image, registering a later image through selecting a control point, cutting out an image overlapping region as a sample region; extracting change information by utilizing the difference of spectral characteristics of different ground objects and adopting an image difference method. According to the the identification capability of the GF-2 multispectral remote sensing data is adopted to better adapt to the characteristics of more change patternspots and small area in a sample area, a high-precision forest change detection result is obtained, and meanwhile, according to the characteristics of the sample area, difference of spectral characteristics among different gr
