福建近海叶绿素a和初级生产力的分布特征

以2001年福建主要港湾的现场调查资料为基础,对该水域叶绿素a含量和初级生产力的分布特征及其对浮游植物生长的限制因子进行了分析和探讨.研究结果表明,该海域的环境因素适合浮游植物的生长繁殖.相关分析显示,叶绿素a和初级生产力与浮游植物呈现显著正相关.无机氮不会成为浮游植物生长的限制因素,而浮游植物生长受控于磷酸盐的几率最大.

Distribution of Chlorophyll. a and Primary Productivity in Fujian Coastal Water

Based on the data of field investigation conducted in the main bays in Fujian during 2000-2001,chlorophyll-a content,distribution characteristic of primary productivity and the role of limitation to phytoplankton growth were analyzed and studied. The results showed that conditions of environment in the sea area seemed suitable for phytoplankton growth.Chlorophyll-a conteat and distribution of primary productivity were positively correlated to phytoplankton growth. The phytoplankton growth was not limited by nitrogen. Phosphate, however, certainly limited the phytoplankton growth.
