摘要
根据2013年6月(春季)和11月(秋季)平潭海坛湾的调查数据,研究了海坛湾叶绿素a的分布特征及其与环境生物因子的相关关系。结果表明,海坛湾春、秋季叶绿素a平均含量分别为3.1 mg/m3和1.1 mg/m3,春季叶绿素a含量呈现从内湾向湾口方向逐渐减小的趋势,秋季略呈湾外侧高于内侧的趋势。春季海坛湾叶绿素a含量高于福建省北部海湾和台湾海峡等历史水平,秋季水平相当。春季叶绿素a含量与盐度、营养盐和浮游动物密度相关,秋季与悬浮物质含量相关。
The marine environmental status in Haitan Bay, Fujian Province, China, was monitored during June and November, 2013. The concentration of chlorophyll a （Chl a） was analyzed to assess its spatial and seasonal variability as well as the correlations with environmental and biological variables. The average Chl a concentration of Haitan Bay in spring and autumn were 3.1 mg/m^3and 1.1 mg/m^3, respectively, higher than and approximately equal with the historical concentrations of Chl a in the bays of northern Fujian and Taiwan Strait in spring and autumn, respectively. Chl a concentration decreased from inner Haitan Bay to outer bay in spring and increased in autumn. The analysis showed good correlations between the concentration of Chl a with salinity, nutrients and density of zooplankton in spring, and with suspended solid in autumn.
