Abstract: Based on the partition of cultivated land，making clear the key point and direction of utilization，it is the necessary work of optimization of cultivated land resources utilization. Taking the Chongyang County as studying area，based on cultivated land productivity calculation，introducing the methods of landscape pattern analysis and scale advantage index，builds up the index system of cultivated land utilization zoning，from 3 angles which are cultivated land productivity potentiality，spatial distribution pattern and agricultural production efficiency. A weighted system of clustering method is used to dividethe cultivated land in Chongyang County，points out the present situation and the developing direction of cultivated land in each partition. The results show that the difference of cultivated land utilization are obvious in each area，the terrain is the main factor for this difference. The cultivated land utilization in Chongyang County can be divided into 3 types：to strengthen intensive and scale utilization in the intensive utilization area，to integrate resources and optimize agricultural production efficiency in the optimized area，to pay attention to protection of high quality cultivated land and development of ecological agriculture in the coordinate development area.
