The study is conducted by taking the sustainable marine development of Hebei Province as the study object and using the dynamic evaluation method that is the mainstream way at home and abroad for evaluation.After establishing the index system with a total system,2 subordinate systems,5 subsystems and 27 evaluation indexes,the evaluation method system composed of index layer evaluation method,empowerment,comprehensive evaluation method,the criteria for the level of sustainable development and coordination degree evaluation method is adopted to search the dynamic evaluation of sustainable development of Hebei ocean in 1995-2008.Results show that during the period of evaluation,the level of economic development was increasingly promoted and the structure of economy was further optimized.Every index of use efficiency of marine resources continued to improve.The important qualities of marine resources continued to degrade,such as the densities of marine biological resources and tideland resources.In addition to the biological health index and storm loss index that were improved in a fluctuant way,other marine ecological indexes were all worsen.The sea water per unit coastline and the occurrence frequency of red tide decreased fastest,followed by coastal wetland forest coverage and the seawater intrusion area per unit coastline.The proportion of eroded coastline decreased slowest.In short,during the period of evaluation,the ocean development of Hebei Province was in the weak unsustainable development state at which the economic growth is the cost of resources and environment.However,the coordination degree of environment and development was increasingly improved,i.e.,the environmental cost for unit economic development decreased continuingly.
