[email protected] Abstract. Cultivated land is the fundamental guarantee of agricultural production, accurate acquisition of information such as the area and distribution of cultivated land and the change characteristics of cultivated land is of great significance for agricultural resource monitoring and production. The development of remote sensing technology provides a new technical scheme for rapid and efficient extraction of cultivated land information.
