胶州湾溢油污染研究

青岛港黄岛油区建成投产后,在扩大石油进出口量的同时,也使事故溢油污染概率增大,对胶州湾海水环境造成了威胁。从已经发生的油污染事件看,溢油多数是由于油船海损,其次是港口机具或储油设备损坏造成的。由于溢油多数是突然发生,在短时间内将大量石油泄漏海中,造成大面积海面或海滩油污染。溢油污染不但造成直接经济损失,而且油污染较长时间内难以清除干净,对海洋生态环境、沿岸旅游环境和社会环境都产生恶劣的影响,因此溢油污染危害早已引起青岛市有关部门的重视,先后开展了油污染监测和预报工作。本文根据胶州湾及邻近海域事故溢油污染预警、预报的需要,给出预报模型和典型天气下黄岛油区溢油行为和污染范围的预测,对有效地预防溢油污染和制定抢救、回收措拖及方案提供了重要依据。

PREDICTION FOR OIL SLICK POLLUTION IN JIAOZHOU BAY

This paper presents numerical modelling (on the spread, transport and ageing of the oil slick from an accidental oil spill in the center of Jiazhou Bay under NE,SW, SE and SW winds) showing that when wind speed is greater than 5m/s, winds exert greater effect than tides on the oil slick; and that if wind changas its direction from N to S during the time of the oil spill, the oil slick will spread to most parts of the east coast of Qingdao.
