Regional land-water resource and agricultural economic system is a dissipative system with complex structure and multiple coupling functions,in which energy,material and information exchange closely between the various subsystems.Meanwhile,the elements influence and revolute with each other.Based on the concepts of coupling and coordination,a coupling-coordination model is built and applied using entropy right method and ArcGIS 10 platform for the evaluation of the land-water resources and agricultural economic system in Heilonggang area.The results showed that the coupling coordination condition of the system was poor,mainly in the primary to intermediate coordination development classes.The development of some areas was strongly imbalanced in coordination.The evaluation results reflected precisely the status of regional land-water resources and agricultural economic development,and could support the decision making for regional resources and economic development.
