Theory, Method And Case Studies Of Marine Economy Sustainable Development

Under the condition that land resources are scarce, population is expanding and environment is worsening day by day, the degree of ocean exploitation is enlarging and new domains are appearing. Ocean stays in more and more important strategic status in national economy and social development. Our country marine resource potential is enormous and marine economy always keeps a fast increasing speed. But with marine economy rising fast, there are many problems of resource wasting, environment polluting and plunderous manage. In order to avoid the disordered state which may appears in ocean exploitation and ensure marine economy, marine resource use and marine environment protection coordinated unification, the strategy of marine economy sustainable development(MESD in short, similarly hereinafter) must be taken.Involving a lot of factors such as society, economy, resource and environment, MESD is a huge ecology-economy-society complex system. It involves the questions of technical, management, appraisal and harmony and so on. So it is impossible to solve all questions in one research. Beforehand research is mostly inclined to some aspects of MESD such as sustainable utilization of marine resources, some marine industry sustainable development and management policies so on. This research is qualitative primarily and can not assurance MESD. Based on before research results, taking the theory of sustainable development as instruction, utilizing the system science thought and the methods of economic geography, system dynamics and model analysis, this article carries on qualitative and quantitative study on MESD. The concrete research content is as follows.First chapter is the part of introduction. This article mainly explains studying background and significance and introduces research structure and innovation spots. Second chapter is the part of research foundation. This article mainly narrates the researching progress of marine economy development and sustainable development and also sums up geography's contribution to sustainable development research. Under this foundation, this article puts forward the science definition and connotation of MESD and analyzes the factors of influencing MESD.Third chapter is the part of rationale of MESD. Being guided by sustainable development theory,based on the thought of system science, from the angles of complexity, systematic, coordinative, ecology restraint way, this article discusses the operation mechanism of MESD. Firstly, this part analyzes the compound ecosystem characteristic. Secondly, through analyzing the restriction factor, this article discusses the system structure and characteristic and designs the system dynamic model of MESD by the software of STELLA in the foundation of analyzing the relation of system dynamics and MESD. Then, this article discusses the quantification method of MESD system coordination through recounting the concept and connotation of coordinating development. Lastly, though analyzing ecology restraint relations of MESD, based on the correlative research of carrying capacity, this article puts forward the connotation and concept model of marine regional carrying capacity and discusses the relationship of marine regional carrying capacity and MESD.Fourth chapter is the part of appraisal index system of MESD. Under the foundation of analyzing the index system's function and connotation, this article summarizes the present research results of index system in sustainable development and MESD and discusses the characteristic of MESD's index system from the angle of system. Then , this article puts forward the principle of founding the index system and designs the appraisal index system involving the system of marine resource and environment, the system of marine economy and the system of social development system. Lastly, this article also discusses the method of selecting index and giving weigh.Fifth chapter is the part of research methods of MESD. First, on the base of region sustainable development, this article forms the concept model of MESD and analyzes the system developing path of MESD. Then, this article summarizes the model analyzing methods and brings forward the way of degree of MESD. Lastly, from the angle of input-output, this article puts forward the method of marine economy input-output based on sustainable development and discusses the way of conceiving the table of marine economy input-output.Sixth chapter is the part of case. On base of the date which is in china marine statistical yearbook and the theory, method and model above, this article studies the problem of MESD in Liaoning province. First, this article carries out analytical comparison on marine resource characteristic, marine economy present situation and marine industrial structure characteristic in Liaoning. Second, this article constructs the appraisal index system of MESD in Liaoning and appraises it by the method of the degree of MESD. This article also establishes the evaluative criteria system of MESD and system coupling of marine ecology-economy-society sustainable development, discusses the level of MESD in Liaoning and the relation of marine ecology-economy-society sustainable development system coupling. Third, this article founds the state space of marine region carrying capacity, estimates marine region carrying capacity in Liaoning and discusses the problem of MESD in Liaoning based on marine region carrying capacity. Then, based on the model of marine economy input-output, utilizing the date of input-output tables of Liaoning in 2002, this article forms marine economy input-output tables of Liaoning and carries on the corresponding analysis, discusses the optimization problem of marine industry. Last, based on the analysis result, this article proposes the way and countermeasure of improving marine region carrying capacity and realizing MESD of Liaoning.Seventh chapter is the part of summary and prospect. This article carries on the summary and review to the whole text and points out further studied direction.
