Abstract: Building waterfowls pond and building fish pond for ameliorating saline land are two different models of wetland utilization on seashore in Jiangsu Province, China. In this paper, ecological-economic benefits of the two subsystems are evaluated with emergy analysis method,and some suggestions are given about sustainable development of seashore. Some emergy indices are calculated as following: the emergy investment ratio (Ir) are 7.07 and 1.02?10-2M; the Export-feedback ratio (Fr) are 0.457 and 3.95; the Actual emergy yield ratio (Yr) are 54.00 and 4.00?103 , the change of stored emergy (Nc) are 3.65?1020J and -5.16?1019J. for waterfowl and fish pond,respecfively. These indices show that: First, in order to reduce the habitat pressure of coastal birds, it is necessary to build waterfowl pond at the edge of core zone of natural reserve on seashore. Second, in order to ameliorate saline land rapidly, it is applicable for suitable use in non-core zone of natural reserve and other seashore area. Third, in order to measure coordination between natural reserve and economic development, it is essential that core zone should be enlarged in natural reserve, and the economic development should be limited in buffer zone of natural reserve and non-natural reserve area.
