The invention discloses a water body abnormity monitoring method based on a multi-source time sequence remote sensing image, and relates to the technical field of water environment pollution monitoring, and the water body abnormity monitoring method comprises the following steps: obtaining to-be-detected multi-source time sequence remote sensing image data, and carrying out the preprocessing of the to-be-detected multi-source time sequence remote sensing image data; and extracting a water area part from the preprocessing result by using a threshold segmentation algorithm, and calculating remote sensing reflectivity image data of the water area part corresponding to the to-be-detected multi-source time sequence remote sensing image data. According to the method, noise can be removed, radiation correction and atmospheric correction can be corrected through preprocessing, meanwhile, the water area part is extracted from the preprocessing result through the threshold segmentation algorithm, spectral information o
