The invention discloses a partitioned satellite task planning method with the maximum area covered by limited resources. The method comprises the following steps: 1, partitioning a rectangular area tobe observed; and 2, distributing observation resources to different partitions and selecting a coverage mode for the different partitions so as to maximize the coverage area corresponding to the formed coverage scheme as much as possible. According to the method, a satisfactory scheme for covering the region target as much as possible by using limited observation resources can be obtained by using proper calculation resources, and balance between calculation resource consumption and solution optimality is achieved, so that satellite resources can be fully utilized in an actual environment, and rapid and effective coverage search is performed on the important region target.
