Abstract： Changsha was taken as an example and spatial autocorrelation method was used to analyze the quantity， quality and ecological characteristic of cultivated land. The major indexes contain cultivated land density， comprehensive quality of cultivated land index and landscape ecological security index. Cultivated land protection zones and key points were determined. This research aims to provide reference for natural resources authority on cultivated land protection policy.
