| 摘 要： | 根据2006年秋季海州湾赤潮监测资料,分析了链状裸甲藻(Gymnodinium catenatum)赤潮发生前后主要营养盐变化特征、赤潮发生与天气的关系.发现:赤潮发生前,海州湾近岸水域严重富营养化,成为本次赤潮发生的条件.赤潮发生过程中,天气晴朗、海面风力小,浮游藻类细胞密度增加,Chl-a质量浓度上升,温度、盐度变化不大,DO和pH值变化较大,N/P升高;营养盐中P降幅最大,P被认为是本次赤潮的限制因子,Si也被大量消耗,但其质量浓度下降滞后其他营养盐.10月6日以后,主要营养盐质量浓度逐渐恢复至正常水平,赤潮开始消退. |
| 关 键 词： | 海州湾 赤潮 浮游植物 营养盐 富营养化 |

| Abstract: | Based on the data for the red tide monitoring in Haizhou Bay in autumn 2006,features of the main nutrient-salts variation which took place in the Gymnodinium catenatum red tide period are analyzed,and the relationship between the redtide occurrence and the weather is discussed.It is found that serious eutrophication had taken place before the red tide occurrence in the near-shore water of Haizhou Bay and it became the environmental conditions of the red tide occurrence.During the red tide period,it was fine... |
