【摘要】 嵊泗列岛位于长江口外,其附近海域是长江口外赤潮的多发区域,我们在其赤潮多发时期的6～8月进行四期监测,结果表明:嵊泗列岛附近海域6～8月海水多处于富营养化状态,浮游植物密度极高,主要优势种夜光藻等均为赤潮种类,极易引发赤潮。海水中的活性磷酸盐含量对限制浮游植物的大量繁殖可能起着较为重要的作用。在监测期间现场还监测到一次中缢虫赤潮的发生。更多还原

【Abstract】 Shengshi island is located in the Yangjtze estuary,where the red tide often occurred.We have monitored in this area four times from June to August in 1999,and the results showed that the sea water in this area was eutrophication,that density of Phytoplankton was very high,and that the mainly dominant species was Noctiluca scientillans and Skeletonema costatum which often cause red tide bloom.The DIP content in the sea water might be play an important role in limiting the phytoplankton bloom.In the period of monitoring we have catched a Meosodinium rubrum red tide.更多还原
