摘要

摘要: 基于2013年8月琼东海域两个连续站的观测资料,对比分析了近岸站位和陆架站位的营养盐和叶绿素a浓度周日变化特征及其影响因素。结果表明:在垂直分布上,近岸站位S1与陆架站位S2的温跃层减弱了营养盐的向上输运;在时间变化上,S1站底层硅酸盐、硝酸盐和磷酸盐浓度具有半日波动的特点,而S2站的营养盐则不具有周日波动的现象,这说明近岸站位的营养盐受到潮汐作用的影响更显著。S1站的叶绿素a分层不明显,夜间的低值可能体现浮游动物的摄食作用,S2站位的叶绿素a分层明显,夜间没体现浮游动物的摄食作用。总体上,琼东海域近岸站位S1和陆架区站位S2叶绿素a和营养盐周日波动都受到温跃层、潮汐、生物作用和光照的影响,但S1站受潮汐作用影响更显著,且S1站叶绿素a浓度还受到浮游动物摄食作用影响。由于叶绿素a和营养盐受到多种环境要素的影响,使得两者相关性不显著。

Abstract: The distribution and controlling factors of diel variation of nutrients and chl a were studied on the basis of 2 continuously measuring stations during the summer (August) in 2013. The results indicated that the thermocline weakened the transportation of nutrients upward. The diel variation of silicate,nitrate,and phosphate on the bottom of nearshore Station S1 appeared a semidiurnal period,but not at offshore Station S2,suggesting that nutrients at nearshore station S1 was influenced by the tidies more obviously. Moreover,the chlorophyll a level at S2 displayed vertical stratification,and low chlorophyll a level at S1 at night reflected the feeding of zooplankton. Our results suggests that the chlorophyll a and nutrients at S1 and at S2 were controlled by the thermocline,tidies,bioglogical effect and light. The tides are more obvious at S1,and the chlorophyll a was also affected by the feeding of zooplankton. It is because chlorophyll a and nutrients are controlled by many environmental factors,making chlorophyll a unrelated to nutrients.
