摘要
依据2013年5月(春季)和10月(秋季)对金塘港区2个航次的叶绿素a和初级生产力调查结果,分析和研究了叶绿素和初级生产力的季节分布和垂直分布特征。春季平均叶绿素a值为0.570μg/L,秋季平均叶绿素a值为0.649μg/L,春季小于秋季。春季调查海域春季平均初级生产力值为22.56 mg C/(m·d)。秋季平均生产力为24.16 mg C/(m·d)。春季初级生产力小于秋季初级生产力。
According to the 2013 May(spring)and October(autumn)of Jintang Port two cruises of chlorophyll a and primary productivity in the survey results,analysis of chlorophyll and seasonal distribution of primary productivity and the vertical distribution characteristics were carried out.The average chlorophyll a value was 0.570 μg/L.The average chlorophyll a value was 0.649 g/L in autumn,and which was less than that in autumn.In spring,the average primary productivity of the sea area was 22.56 mgC/(m·d).In autumn,the average productivity was 24.16 mgC/(m·d).The primary productivity in spring was less than in autumn.
