摘要
基于深圳市2000-2011年《海洋环境质量公报》,分析了深圳近岸海域海水水质、赤潮发生情况和沉积物质量。结果表明,深圳近岸海域污染状况总体有加重迹象;赤潮发生先降后升,最近几年变化平缓,发生区域以大鹏湾居多。赤潮引发种以甲藻居多,并逐年增加;沉积物东部海域优于西部,质量同样有下降趋势。深圳近10 a来快速增长的经济带来的大量陆源污染可能是深圳近岸海域污染的主要原因。
Based on the"Marine Environment Quality Bulletins of Shenzhen"from 2000 to 2011,offshore water conditions of Shenzhen were analyzed in water and sediment qualities and algal blooms. It revealed that the pollution of offshore waters was generally increasing. The frequencies of algal blooms decreased,then increased and changed moderately in recent years. Dapeng Bay was the region of the most outbreaks. The most causative species were dinoflagellate and blooming increasingly. Sediment quality was overall deteriorating. Sediments of the eastern waters were better than those of the western. The environmental deterioration was chiefly resulted from land-based pollutants caused by the economic development in recent 10 years.
