【摘要】：海洋生态经济可持续发展的研究既是生态经济研究的重要领域,也是海洋经济研究的重点领域。运用能值分析构建中国海洋生态经济系统能值分析模型和指标体系,以中国沿海地区及其附近海域为研究区域,利用2013年的数据对中国海洋生态经济系统的可持续发展水平进行能值测度。研究表明:(1)2013年,中国沿海各省的海洋生态经济总能值为1.70×10~(24)sej,可更新资源能值占主体地位。(2)受沿海各省海洋经济发展水平不同和区域海洋资源储量影响,中国沿海地区海洋生态经济能值密度分布差异较大,能值货币比率以上海为界,南高北低,高中低3种能值产出率结构并存且以中能值产出率结构为主。(3)中国海洋生态经济系统的生态承载力以高承载力和较高承载力为主,但局部地区海洋生态承载力偏低影响区域海洋生态系统平衡。中国海洋生态经济系统环境负载率较大,环境负载率高的地区与我国海洋经济发达地区高度耦合。(4)从可持续发展指数来看,中国海洋生态经济发展的整体可持续性较好,局部地区环境负载率过大和生态承载力偏低严重制约着区域海洋生态经济的可持续发展。
[Abstract]:The research is an important research field of ecological economic marine ecological economic sustainable development, but also the focus of the study of marine economy field. Using the emergy analysis of construction of marine eco economic system China emergy analysis model and index system of coastal areas in Chinese and surrounding areas as the study area, by using the data of 2013 to measure the level of sustainable development of marine eco economic system of China. Research shows that: (1) in 2013, Chinese coastal provinces of the marine eco economic value is always 1.70 * 10~ (24) sej, renewable resource value accounted for the dominant position. (2) the marine economic development level in different coastal provinces and regional marine resources reserves, marine ecological economy the coastal area China emergy density difference, emergy dollar ratio in Shanghai is bounded by the North South low 3 high middle low rate structure coexist and in energy output The rate of structure. (3) the ecological carrying capacity of marine eco economic system China with high capacity and high bearing capacity, but the local area of marine ecological carrying capacity is low impact the balance of regional marine ecosystem. The environmental system of marine eco economic Chinese load rate is larger, the environment load rate and high area of China's marine economy developed in a high degree of coupling. (4) from the sustainable development index, the overall China sustainable development of marine eco economic good, local area environment load rate is too large and the ecological carrying capacity is low seriously restricts the sustainable development of regional marine economy.
