Abstract


Marine environment, the system is an important part of the economic system of regional marine environment, an important part of that is also the marine environment of coastal areas as well as regional economic system is essential for sustainable development. Sustainable Development of the economic system of regional marine environment, the elements of the system of regional marine environment, the process, its role in support of the development of the regional economic system, as well as regional economic development impact of the regional marine environment caused by these problems analysis and research. Sustainable development of the regional marine environment, economic system, on the regional scale oceanographic properties, refers to the coastal areas of regional economic system and regional environmental systems, especially with the marine environment systems to achieve a coordinated and sustainable the development of the state or toward the development of this state, the interaction between this state to achieve the essence of regional economic system area (marine) environmental systems toward a virtuous circle direction of sustainable development. Value theory and its analysis methods to the study of economics from the energy flow provides a new perspective to understand and analyze regional environmental economic system and its sustainable development issues, economists also able they are familiar analytical framework, the objective to evaluate the environmental resource elements and the economic process, the relationship between economic development to provide a quantitative analysis tool. Emergy analysis model of the regional marine environment, economic system, based on emergy analysis between theory and build cost - benefit analysis method to study the coastal areas of regional economic system area (marine) environmental systems, and regional external economic environment interaction analysis tools, it clearly reflects the environmental elements of the area (marine) environment within the system, the environmental process, the process of transformation of the economic elements of resource elements in the environment within the economic interface, regional economic system within and outside the region, environment, economy elements of demand and its impact area (marine) environment. Combination of regional marine environment, economic value analysis model built emergy index system, especially the newly constructed emergy evaluation indicators - economic emergy yield ratio EEYR, integrated environmental load rate ILER and regional sustainable development of the energy value The index EIRSD, provides a quantitative analysis of the indicators of the tools for the sustainable development of the economic system of the study area, the marine environment starting from the regional economic system area (marine) environment interaction problem. Regional marine environment in the Bohai Sea economic system on the one hand at the input end of the regional economic development faced by a large proportion of demand for factors of non-renewable resources, on the other hand, in its discharge end facing increasing pressure of environmental pollution. Environmental pollution and continue to increase due to the economic development of provinces and cities in the Bohai dependence on non-renewable resources invested, so that it can not cover due to the growing use of non-renewable resources invested in energy conservation and resource recycling pressure, so that the sustainability of the economic system development of the Bohai Sea region marine environment unfavorable situation facing declining. Therefore, the achievement of sustainable development of the marine environment, the economic system of the Bohai Sea region, requires the district provinces and municipalities as a platform to build integrated development pattern of the Bohai Sea region, to establish a regional development strategies rely on the ocean, facing the ocean, marine development and protection of the marine starting from the actual situation around, continue to promote energy conservation and recycling economy, vigorously develop the various the circulating energy development and utilization of renewable resources and clean type, export-oriented economic development and industrial structure optimization and upgrading combine.
