Abstract
As a result of rapid growth in reclamation for aquaculture and salt industry driven by economics, the sea area and water quality in Dingzi Bay were significantly reduced, leading to apparent decrease in benefits of aquaculture and salt industries, the severe loss of coastal wetland as well as the reduction of biodiversity due to large-scale reclamation. The water quality in Dingzi Bay was found to fall below the standard of second kind level in accordance with <Marine Functional Zoning of Shandong Province> (2004)(In marine functional zoning of China, the sea water quality is divided into four kinds standard. The sea water quality which is lower than the second kind level cannot be used for aquaculture and salt production). According to the <Marine Functional Zoning of Shandong Province> (2004), aquaculture and salt industry are the two leading industries in Dingzi Bay, but at present the water quality in Dingzi Bay was not suitable for aquaculture and salt industry development, and the aquaculture and salt industry were incompatible with the needs of marine economy sustainable development and marine environmental protection. Nevertheless, the profound cultural background and Location advantage of Dingzi Bay was not fully developed. Therefore, the remediation and restoration of Dingzi Bay were urgently needed to improve regional environmental, optimize the coastal industrial structure, make good use of cultural tourism resources, and enhance regional economic and social development, the goal of which is to construct the marine culture tourism industry cluster district in Dingzi Bay. Based on dramatic changes in resources and environment in Dingzi Bay and unsuitability for current aquaculture and salt industry development, so it is suggested that the marine functional zoning in Dingzi Bay in <Marine Functional Zoning of Shandong Province> (2004) should be modified in order to restore the marine environment and promote regional economic development.
