摘要:

通过对海洋生态系统特征的分析,构建了海洋生态系统可持续发展能力评价指标体系;运用信息熵构建了海洋生态系统可持续发展能力评价模型,分析各个指标对海洋生态系统可持续发展能力的影响,从而提出提高海洋生态系统可持续发展能力的相关性的措施。研究结果显示:2004~2011年,人类对海洋自然生态系统的需求日益加大;在国家和政府的重视下,海洋污染问题得到了改善,海洋生态系统内部朝着有序健康方向发展,自然生态系统的支撑能力不断提高,中国海洋生态系统可持续发展能力总体呈上升趋势。

Abstract:

Scientific evaluation of Marine ecosystem sustainable development ability is an important basic to grasp accurately whether healthy development of Marine ecosystem or not. In the Marine economy sustainable development concept, the sustainable development of Marine ecosystem is a foundation, and of great significance for human development. However, as the global population increases and an increase in the demand for resources, the Marine resources excessive consumption, and water eutrophication and serious consequences such as ecological variation, Marine ecosystems are under great pressure. Therefore, how to determine scientifically whether Marine ecosystem health development or not, has become an important problem under Marine economy sustainable development target. Large Marine ecosystem is an open system, which has the general characteristics of complex systems, such as open, dynamic, metabolic and adaptive. Marine ecosystem exchanges energy with the outside world, whose structure changes with the external disturbances and internal fluctuation change, and is a dynamic and stable ordered structure with a strong vitality. It has not only different pattern in the space and function, also shows a succession stage on time. Marine ecological system conforms to the characteristics of dissipative structure, and the change process shows the dissipative structure system characterized by the entropy change. The evaluation index system of sustainable development ability of Marine ecosystem was founded based on the characteristics of Marine ecosystem and understanding of Marine ecosystem sustainable development connotation. The sustainable development ability assessment model for Marine ecosystem was built up based on information entropy. The information entropy theory is based on probability and numerical statistics. Entropy in this article is a quantitative description of Marine ecosystem state, to evaluate Marine ecosystem sustainable development ability and the trend. Thus it analyzed various indexes' impacts on the sustainable development ability of Marine ecosystem. By establishing a model based on support input entropy, pressure output entropy, consumption metabolism entropy and restore metabolic entropy model , the evaluation for China's Marine ecosystem sustainable development ability was explored, so as to accurately grasp the Marine ecosystem health development, further to provide the references for government's guideline, and then put forward some countermeasures to promote Marine ecosystem sustainable development. The main conclusions of this study could be summarized as follows: 1) the requirements of Marine ecosystem on the natural ecosystem continuously grew; 2) under the attention of state and government, Marine pollution problems have been improved, and Marine ecosystem moves towards orderly and healthy direction; 3)the ability of the natural ecosystem to support continuously showed an increasing trend, and Marine ecosystem sustainable development ability was on the rise as a whole.

Key words: China′s marine ecosystem, entropy change, information entropy, sustainable development
