Monitoring-assessing-prewarning system for agricultural land resources security

With the explosive growth of population and rapid development of economy, the security of food and agricultural land resources have been paid more and more attention by researchers and government. The implication of agricultural land resources security and its causes were analyzed. The standard plot system of agricultural land classification and its function were discussed. According to the national agricultural land classification result and the current land management information database, the monitoring-network, evaluation method and index system of agricultural land resources security were established. Finally, this paper put forward the establishment of monitoring-evaluation-warning system framework to ensure agricultural land resources security, and this system would play important role to improve land resources management and protect agricultural land.
