【摘要】 利用1983～1999年8个航次对钦州湾的调查资料,描述了不同时期油类分布特征,讨论了油类含量与环境因子之间的关系,并对该湾油类的污染程度进行了分析。结果表明:该湾油类多具有春夏季明显高于秋冬季、开发初期明显高于中、后期的分布特征;与环境因子之间的关系以秋季较为密切,冬季次之,春夏季较差,其中物理过程及营养盐的降解作用占主导控制地位,生物过程次之;其污染状况以1983～1984年较为严重,1996～1997年次之,1990年和1999年水质状况较好。更多还原

【Abstract】 Based on 8 voyages of investigation data on pollution in QinZhou Bay 1983～1999, the oils characteristic distribution in different periods of time, a discussion on the relationship between the content of oils and environmental factors, and the polluted level in this Bay were made. The results showed that the content of oils in this bay was higher in spring and summer than in autumn and winter, and higher at the beginning of the developing period than in the middle and late periods. The relationship between the oils and environmental factors were changed in different seasons. It was closer in autumn, dropped in winter, bad in spring and summer, and the physical process and the decomposition of nutrients are dominant, the biological process worked less, The oils polluted situation was relatively serious in 1983 and 1984,than in 1996 and 1997,and the quality of water was good in 1990 and 1999 in Qinzhou Bay.更多还原
