摘要
根据2004年10月对南黄海4个断面29个站位表层、20 m层和50 m层水体中盐度、水温、pH值等参数的测定数据,分析了该季节溶解无机碳的组成和分布特征,探讨了影响其分布的主要因素。结果显示,调查期间南黄海水体中溶解无机碳及其各组成部分的水平分布差异显著;在垂直方向上,表层和20 m层各参数之间浓度总体上差异不大,但均与50 m层存在较大的差异。盐度、温度、生物活动和环流对各参数的分布具有重要影响,但对不同参数的影响程度不同。
The field observation was carried out in Oct. 2004, based on the data collected from the southern Yellow Sea, the concentration, distribution and composition of the dissolved inorganic carbon in surface, 20 and 50 m depth waters were examined. A total of 29 stations was established four parallel latitudinal transects. The results showed that the distribution of DIC and its constituents were significant spatial differences. In vertical direction, on the whole, the studied parameters' values in surface and 20 m depth waters were similar, while they were quite different from those in 50 m depth. Salinity, temperature, biologic activities and circumfluence of water masses have important influence on the distribution and composition of DIC, but the degrees of their influence on these parameters were different from one to other with water depth.
