本文根据1996年4月“中韩黄海水循环及物质通量合作研究”项目的调查资料,首次对整个南黄海海域春季海水化学要素的分布特征进行了分析和探讨。结果表明,春季南黄海南部(34°N以南)溶解氧含量及分布主要受外海暖流水所控制,而中北部则主要受生物及生化活动的影响。春季南黄海上层水体中的营养盐主要来源于长江口附近海域高营养盐水的输入。南黄海南部及北部化学要素基本呈垂直均匀分布,而中部的深水区化学要素的垂直分布呈现明显的分层现象,而且可能存在底层海水涌升现象。
Based on the survey data of the “Yellow Sea water cycle and material flux cooperation” project in April 1996, this paper analyzes and discusses the distribution characteristics of spring seawater chemistry in the whole South Yellow Sea for the first time. The results show that the dissolved oxygen content and distribution in southern South Yellow Sea (south of 34 ° N) in spring are mainly controlled by the outlying sea warm water, while the central and northern parts are mainly affected by biological and biochemical activities. Nutrients in spring waters in the upper Yellow Sea mainly come from high-nutrient water input in the sea near the Yangtze Estuary. The chemical elements in the southern and northern South Yellow Sea are basically vertically and evenly distributed, while the vertical distribution of the chemical elements in the deep water area in the central part of the southern Yellow Sea shows obvious stratification, and there may be the phenomenon of bottom water rising.
