| 摘 要： | 采集了中国东海(2009-12~2010-01)35个站位的海水样品,其中包括6个站位的垂直断面。用TPTZ方法测定了溶解态的单糖(MCHO)、多糖(PCHO)和总糖(TCHO)的浓度,对其水平分布和PN断面分布进行了研究。结果表明,受到长江冲淡水和黑潮水的影响,表层海水中MCHO、PCHO和TCHO浓度的水平分布表现出由近岸向外海递减的分布趋势。PN断面由于受冬季东北季风的影响,水体混合强烈,使得MCHO、PCHO和TCHO浓度在垂直方向上分层无明显规律。对长江口外3个断面海水中TCHO浓度与环境因子做了相关性研究。结果表明,TCHO浓度与盐度和温度呈显著的线性负相关,与Chl-a浓度呈线性正相关。

| Abstract: | Seawater samples were collected at 35 stations,including 6 stations in the vertical section,in the East China Sea from December 2009 to January 2010.Concentrations of monosaccharides(MCHO),polysaccharides(PCHO),total dissolved carbohydrate(TCHO) were measured with TPTZ method,and their horizontal and PN vertical distributions were studied.The results showed that the horizontal distributions of MCHO,PCHO and TCHO were obviously influenced by the Yangtze River effluent and the oligotrophic Kuroshio waters,and... |
