摘要:
基于信息熵理论,以溢油事故对海洋天然渔业损害为切入点探讨海洋生态系统可持续承载力损害评估方法。论文从生态系统状态、功能、污染、修复等四个方面构建了熵流和熵产生指标体系,以“塔斯曼海”轮溢油事故为例进行计算和评估,结果表明:溢油使海洋生态系统的价值产出能力下降94.7%、总的承载力下降194.9%,溢油治理的效果小于溢油对生态承载力的损害。本评价是现有溢油生态损害评价的补充,可为长期生态损害评估、生态修复和环境管理决策提供科学依据。

Assessment of Oil Spill Damage to the Sustainable Carrying Capacity of Natural Fisheries Based on Information Entropy

Abstract:
Based on the theory of information entropy, the damage assessment method of sustainable bearing capacity of marine ecosystems has been discussed here, with the focus on the impact of oil spills on marine natural fisheries. The indexes system of the entropy flow and entropy generation has been constructed from four aspects: the state, function, pollution and repair of the ecosystem. Taking the “Tasman Sea” oil spill accident as an example, the result of calculation and evaluation shows that the oil spill reduced the production capacity of the marine ecosystem by 94.7%, and reduced the total carrying capacity by 194.9%. This evaluation is a supplement to the existing ecological damage assessment of oil spills and provides a scientific basis for the Long-term ecological damage assessment and the decision-making on the ecological restoration and environmental management.
Key words:  oil damage assessment  information entropy  natural fishery  Tasman sea oil spill
