摘要

摘要: 重点研究了南黄海西部36°N断面水文、生源要素的四季变化特征,阐明了该断面诸参数四季变化的主控因素,并以此反映和指示了与其相关海域的生态环境特征。结果表明:黄海冷水团及黄海暖流具有季节性演替变化规律;秋季跃层以下水体是一部分夏季冷水团残留水和黄海暖流水的混合水;断面西侧在四季均存在小范围的低盐冷水现象(即青岛冷水团),其位置的季节变动跟黄海冷水团和黄海暖流边界的变化密切相关。水体层化、生物化学作用以及垂向混合过程是影响各生源要素断面分布及其季节变化的主要因素;在秋、冬季,均发现断面西侧低盐冷水附近海域有一营养盐高值区;断面深水区乃至黄海冷水团海域在四季均存在营养盐跃层,其与水文跃层、水体稳定度及生物化学作用密切相关。同时,还提出黄海冷水团海域对营养盐具有"夏储(贮)冬输"作用的观点。

Abstract: The seasonal variation and the main controlling factors of the hydrological characteristics and biogenic elements at 36°N transect in the western Southern Huanghai Sea was illustrated,moreover,the important ecological behavior in the related sea area was also reflecting and indicated.The result showed that:(1)The Huanghai Sea Cold Water Mass(HSCWM)and the Huanghai Sea Warm Current(HSWC)at 36°N alternated seasonally;the water body under the thermocline in autumn was the mixed water which not only retained the characteristics of the Cold Water Mass,but also had the features of the warm water;a low-salinity cold water patch(Qingdao Cold Water Mass)existed in the west of the section in four seasons,and the seasonal variation of its location was closely related to the boundary of the HSCWM and HSWC.(2)The stratification,bio-chemical effect and vertical mixing process were the main factors influencing the distribution and seasonal variation of the biogenic elements;in autumn and winter,a high-nutrients area was found near the low-salinity cold water in the west of the section;the nutricline exited in the deep waters of the section and the sea area of the HSCWM in four seasons,which was closely related to the hydrological thermocline,water stability and bio-chemical effect.Meanwhile,a viewpoint was also proposed in this paper that the sea area of the HSCWM had the function of nutrients stored in summer and exported in winter.
