There are great potentials for exploiting beach resources in Bohai Rim which not only account for over 1/3 of those of the country's total but expands constantly along with the accumulative increase of river sediment load entering into sea. However, as the eco environment of the beach is fragile, the exploitation and utilization of beach resources should follow the principle of integration, steoroscope, high efficiency, and sustainable use. Models suitable to local conditions should be adopted in the sustainable exploitation and utilization of beach resources. These models include the adoption of protective integrated exploitation of agriculture, vertical eco utilization of fish pond platform field, farmland eco forest network construction, integrated amelioration of beach grassland, green eco protective industry and seawater cultivation, sea intrusion prevention and control to guarantee high yield technique, eco tourism exploitation and utilization, etc..
