Regional land-water resource and agricultural economic system is a dissipative system with complexstructure 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 theconcepts of coupling and coordination

a coupling-coordination model is built and applied using entropy rightmethod and ArcGIS 10platform 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 waspoor

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 regionalland-water resources and agricultural economic development

and could support the decision making for regional resources and economic development.
