本文对１９９０年春、秋季进行的浙江海岛海域叶绿素浓度和初级生产力的观测资料作了分析。结果表明，春季叶绿素ａ浓度和初级生产力均高于秋季。其空间分布基本上为浙南海区高于浙北海区高于浙中海区，表层叶绿素ａ浓度高于中层和底层。测区光强是叶绿素ａ浓度和初级生产力的主控因子。在离岸较远的南麂列岛、台州列岛、中街山列岛和马鞍列岛等海域的叶绿素ａ浓度和初级生产力均高于受混浊水控制的近岸海岛海域。
In this paper, the observation data of chlorophyll concentration and primary productivity in the waters around the island of Zhejiang in the spring and autumn of 1990 were analyzed. The results showed that both chlorophyll a concentration and primary productivity in spring were higher than those in autumn. Its spatial distribution is basically higher than that in the sea area of southern Zhejiang and higher than that of Zhejiang and Zhejiang provinces. The concentration of chlorophyll a in the surface layer is higher than that in the middle layer and the bottom layer. The light intensity of the area is the main controlling factor of chlorophyll a concentration and primary productivity. Chlorophyll a concentrations and primary productivity in the offshore waters such as Nanji Islands, Taizhou Islands, Zhongjieshan Islands and Ma’an Archipelagos offshore were higher than those in the nearshore islands controlled by turbid water.
