摘　　要：湄洲湾夏季浮游植物有机碳的调查结果表明，活体有机碳［（ＰＯＣ（Ｂ）］含量为４２．５～１８５．０μｇ／ｄｍ３，平均值为７７．５μｇ／ｄｍ３；ＰＯＣ（Ｂ）和叶绿素（Ｃｈｌａ）的转换系数为６２．４；由三磷酸腺苷（ＡＴＰ）计算所得ＰＯＣ（Ｂ）要比由光合作用速率（ＰＲ）所计算的结果大。同时，同化系数（ＰＩ）的变化为０．７８～２．２２ｈ－１，它的垂直变化与ＰＯＣ（Ｂ）分布有关。氮是湄洲湾初级生产力的限制性营养盐。The organic carbon of phytoplanktonwas measured in MeiZhou Bay in the Summer of 1992.POC(B) Content varied in 42.5￣185.0 μg/dm 3,with an average concentrtiom of 77.5 μg/dm 3.The relationship between POC(B) and chlorphyll a content can be expressed as following,POC(B)=62.4 chla.The organic Carbon of phytophankton measured by ATP was hight than that by 14 C tracer method.The growth of phytoplankton was limited by the lack of nitrogen in Meizhon Bay.The supply and cycling of nutrients play an important role in photosynthetic index and primary productivity.
