| 摘 要： | 通过对厦门同安湾2003年5月28日至7月21日以地中海指管藻为主的硅藻赤潮的跟踪监测,研究了赤潮发生前后,海域水环境中水温、盐度、pH值、DO、COD、无机氮(D IN)、活性磷酸盐(PO4-P)、叶绿素a含量与赤潮种群细胞密度之间的关系,并对此次赤潮发生的机理进行了探讨。结果表明,海水中丰富的无机氮和PO4-P为赤潮的发生提供了营养基础,适宜的水温和盐度的变化可能是诱发硅藻赤潮的原因之一,海水中PO4-P则是硅藻赤潮的主要限制因子之一,海水中DO含量变化可作为赤潮预报的主要特征指标。

| Abstract: | This paper investigated water temperature,salinity,pH,Do,COD,DIN,DIP and Chla concentration before and after the diatom bloom induced by Dactyliosolen mediterraneus in Tongan Bay,analyzed the relationship between these items and cell density,and discussed the blooming mechanism in this area.The results showed that high concentrations of DIN and DIP provided nutrient basis of blooming,temperature is the key factor trigging the development of blooming.DIP was the major limited factor for diatom's blooming.The results also indicated that DO could be used as an indicator for forecasting blooming. |
