灾难性的海洋石油污染

Disastrous ocean pollution of petroleum

较详细地分析了海洋石油污染的概况、重大溢油事件及其对海洋生态环境的严重破坏。除了油船海难事故所造成的海洋石油污染之外，海上油田开发是另一个重要的污染源、最大的一次油船事故直接经济损失可达１００万美元．而海洋石油泛滥对海洋生态环境的破坏所造成的（间接）经济损失．还远远超过其直接经济损失。文章从海洋生态系统保护的角度出发，对目前石油污杂物的净化方法作了简要的讨论。

This paper sums and analyses pollution of ocean petroleum, its situation, origin, split oil event and their damage to the marine ecological environment. Oil tanker shipwreck, as well as exploiting oil field at sea, are important polluting sources. The greatest oil tankers' shipwreck cause direct economic loss up to a billion dollars, which is far less than indirect economic loss from destruction of eco-environment by petroreum pollution. Based oil protection of ocean ecological system, the exsisting method to purify petroleum pollutant is discussed
