摘要

摘要: 在珠江口、广东沿岸及南海北部三个航次生物-光学数据的基础上,研究了色素打包效应和色素成分的变化对浮游植物吸收系数的影响,结果表明,两种因素对吸收系数都有较大的贡献,但在不同的水体它们的影响程度各有不同.对网采浮游植物含量较高的珠江口和广东沿岸的水体而言,色素打包效应较强,对675 nm处比吸收系数的贡献平均分别为40%和20%;对微型浮游植物占主导地位的南海北部航次的水体,打包效应较弱,对675 nm处比吸收系数的影响平均仅为6%.采用多元线性回归的方法对吸收光谱进行分析,发现除叶绿素a之外的辅助色素对吸收系数的贡献主要表现在蓝绿光波段,三个航次440 nm波长处对总吸收的贡献平均分别为44%,43%和53%,其中对珠江口和广东沿岸航次的水体主要是光合类胡萝卜素的吸收贡献,而对南海北部航次的水体除了光合类胡萝卜素以外还要受到光保护类胡萝卜素的影响.由于河口、近岸和外海水体藻类粒级结构和辅助色素成分对浮游植物吸收系数的贡献有明显的差异,在南海北部水体建立比较精确的生物光学模型时,需考虑藻类粒级结构及色素成分对浮游植物吸收系数的影响.

Abstract: Data from three cruises conducted in the Zhujiang River (ZR) Estuary, costal waters of Guangdong (CWGD) of China and north of the South China Sea (NSCS) were examined to access the relative importance of pigment composition and package effect in modifying the phytoplankt on specific absorption coefficients.The three cruises differed widely in their phytoplankt on assem blages with large cells dominating the ZR and CWGD cruises and small cells dominating the NSCS cruise.And therefore the package effect for the ZR and CWGD cruises is greater than that of the NSCS cruise, with their estimated contributions to the phytoplankt on specific absorption coefficients at 675 nm being 40%, 20% and 6% respectively.Using the multiple regression analysis approach, pig ment concentrations for each sample were calculated.The accessory pigments, except chlor ophylla, contributed to absorption mainly in the blue-to-green region of the spectrum, for the ZR, CWGD and NSCS cruises, their absorption accounting for about 44%, 43% and 53% on average to total phytoplankton absorption at 440 nm.A mong the accessory pig ments, the photosynt hetic carotenoids played the dominantrole in the ZR and CWGD cruises, while in the NSCS cruise the phot oprotectant carotenoids and the photosynt hetic carotenoids had important contributions.Since the variations of size structure of algal population and the accessory pigments contributed differently to the variability in the phytoplankt on specific absorption coefficients for estuary, coastal waters and open oceanic waters, it is suggested that in order to set up a more perfect bio-optical algorithm in the NSCS, the variations in the optical properties of phytoplankt on caused by the pigment package effect and changes in the relative abundance of accessory pigments should be incorpo rated.
