摘要

摘要: 分析研究了2001年春季黄海、东海颗粒有机碳(POC),结果表明POC的浓度为2~3815μg/dm³,其平面分布呈现近岸高、远岸低的特点.海水表层POC浓度与三磷酸腺苷(ATP)呈显著的正相关,这表明2001年真光层POC主要是海洋生物源.对不同海区POC垂直分布的影响因素做了探讨:长江口附近受总悬浮颗粒物浓度的影响,POC呈现表层低、底层高的特征;陆架区POC的垂直分布是生物活动与水文条件(海水混合、层化)等因素共同作用的结果;在离岸较远的深水区,影响POC垂直分布的主要因素是大洋海水的性质.由海区4个周日连续站的观测结果得知黄海区POC的周日变化主要受生物周日活动的影响,而在东海区POC周日变化除了受生物周日活动影响外,还分别受到潮汐作用以及海水水团周日变化等因素的影响.

Abstract: Particulate organic carbon(POC) was studied in the Huanghe Sea and the East China Sea in the spring of 2001.The results show that the concentrations of POC range from 2 to 3.815g/dm³ and strongly correlated with ATP in the euphotic layer.It is indicated that POC in the euphotic layer is primarily of marine biological origin.High value of POC concent ration was found near the shore and the value decreased seaward.The factors that affected POC vertical distributions were different with the location of stations.Near the Changjiang River mouth,being influenced by the concentration of total sespended particulate matter,the concentration of POC is low in the surface layer and high in the bottom layer,while in the shelf area,it was mainly controlled by biological activity and hydrological conditions.Otherwise,in the shelf break of the East China Sea,the vertical distribution of POC was controlled by the charact eristics of the deep ocean water.The diurnal variety of POC was affected by biological activity in the Huanghe Sea,while tide and alternation of water mass together with biological activity affect the diurnal variety of POC near the Chang jiang River mouth and Zhejiang Province in the East China Sea.
