利用2003年春季(4月)和秋季(9月)两次对南黄海及东海北部海域Ⅱ类水体悬浮体质量浓度的调查资料,得到了夺海域近期悬浮体的平面分布特征,并分析了海流对夺海域悬浮体分布的影响。结果表明,本海域春季悬浮体质量浓度明显高于秋季;爱黄海沿岸流、黄海暖流及台湾暖流的影响,春季苏北浅滩悬浮体呈西北-东南舌状向深海运移,秋季悬浮体以苏北浅滩高值区为中心向外海扩散;长江及杭州湾入海泥沙基夺都沉降在123°30′E以西的海域内。
The concentration data of total suspended matter (TSM) in the southern Yellow Sea and the northern East China Sea were collected in April and September, 2003. According to the information of TSM and ocean current, this paper got the distributions of surface and bottom of suspended matter in the study area, and analyzed the connection between them. The analysis result shows that the concentration of TSM in spring is higher than that in autumn. Because of the affection of the Yellow Sea Longshore Current,the Yellow Sea Warm Current and the Taiwan Warm Current, suspended matter of Subei has been transported form northwest to southeast in spring. And in autumn, suspended matter diffused from Subei which is the highest concentration of TSM to open sea. The suspended matter coming from the Yangtze Estuary and Hangzhou Bay can not cross to the east of 123°30′E both in spring and autumn.
