| 摘 要： | 本文分析了东、黄海典型海区3个测站在2000~2003年间4个航次的叶绿素a周日变动特征,结果表明由于地理环境、水文特征以及季节差异,各海区叶绿素a表现出各自不同的变动特点.在东海陆架区,日变化上表层各粒级主要以半日周期为主,受黑潮入侵程度不同而略有变化;长江口由于受到潮汐的影响,各粒级的日变化同潮汐的涨落相对应,主要为半日周期;黄海中部海区叶绿素a尤其是NANO级浮游植物在周日变化上以全日周期为主,受黄海冷水团强弱不同而不同.本文进一步应用渐近回归初步分析了多种环境因子对叶绿素a周日变化的影响.

| Abstract: | The diel variations of the chlorophyll a(Chl-a) concentration were studied during 4 cruises between 2000 and 2003 in the typical regions of East China Sea and Yellow Sea.Results showed that the variation patterns of 3 size fractions of Chl-a had significant difference for different waters due to the heterogeneity of the geographic environments,the hydrological conditions and seasons.In the shelf of East China Sea,the cycle time was basic 12-hour and it had some changes because of the inbreak of the Kuroshio;Affected by the tide and the diluted water from Changjiang River,the cycle time of Chl-a was also 12-hour.It was 24-hour for one cycle in the central Yellow Sea and varied by the Yellow Sea cold water mass.The controlling factors were identified by stepwise regression for the most environmental factors in this paper. |
