摘 要: | 通过对2010年6月7—13日发生在福建定海湾的一次东海原甲藻与夜光藻双相赤潮进行跟踪监测,分析并探讨了该次双相赤潮生消过程。本次赤潮暴发时海区表层水温范围为22.8~23.2℃,盐度范围为28.24~28.36;本次赤潮暴发后,监测结果显示该海区表层水体中夜光藻的大量存在对东海原甲藻的快速增长无摄食压力,而且在夜光藻大量存在的表层水体中活性磷酸盐及氨氮含量与正常海区相比均明显偏高,另外海区表层水体中东海原甲藻在赤潮暴发后仍能快速生长。

A brief analysis for a bilateral red tide of Prorocentrum donghaiense and Noctiluca scintillans in Dinghai Sea Zone of Fujian Province |

Abstract: | This paper analyzed and discussed the process of a bilateral red tide of Prorocentrum donghaiense and Noctiluca scintillans, which occurred in Dinghai Sea Zone of Fujian Province during June 7 and June 13 in 2010, based on tracking and monitoring of it. The ranges of the surface water temperature and salinity dur-ing the bloom were 22. 8~23. 2℃ and 28. 24~28. 36, respectively. The monitoring result showed that Noc-tiluca scintillans abounding in the surface water posed no pressure on rapidly increasing of Prorocentrum dong-haiense population in the respect of feeding, and the content of PO3-4 -P and NH4+ -N in the surface water where Noctiluca scintillans abounds was significantly higher than normal sea areas. In addition, the popula-tion of Prorocentrum donghaiense in near shore waters could still grow rapidly after the red tide outbreak. |
