一、前言海水中的叶绿素主要存在于浮游植物体内,是这些植物借以进行光合作用的主要色素。叶绿素含量同光合作用速度和生物量有着直接的关系。植物体通过叶绿素的光合作用,进行能量转换,是生产有机物或生物产品的基础。因此,50年代就有人根据叶绿素含量来估计水域生产力。随着测试仪器、技术和方法的改进及标准化,海水叶绿素含量的测定越 I. Introduction Chlorophyll in seawater is mainly found in phytoplankton and is the main pigment from these plants for photosynthesis. Chlorophyll content has a direct relationship with photosynthesis rate and biomass. Plant through the photosynthesis of chlorophyll, energy conversion, is the production of organic or biological products based. Therefore, some people in the 1950s estimated the water productivity based on the chlorophyll content. With the improvement of testing instruments, technologies and methods, and standardization, the determination of chlorophyll content in seawater
