Damage Assessment of Marine Ecosystem Service Function Loss Caused by Oil Spill

摘要

For the quantitative calculation of the marine ecosystem service value loss caused by the oil spill, the damage assessment standards of marine ecosystem were established here based on the related knowledge of environmentology, ecology, chemistry, ecotoxicology and so on. First, the types of marine ecosystem and their service functions were classified, then the health assessment on the marine ecosystem was conducted by using Index System Method, and the marine ecosystem service function loss rate was calculated by using the sensitivity analysis method. Finally, the marine ecosystem service value loss of polluted sea area was assessed according to the average public value of different marine ecosystems, and the loss caused by the "Tasman Sea" case was calculated by applying the methods above.
