根据1962 年-2006 年近半个世纪116 航次的调查和历史资料,讨论了胶州湾营养盐及其结构的长期变化和对生态环境的影响.近50 年来,胶州湾营养盐及其摩尔比都呈现明显的增加趋势,特别是从1990 年代至2000 年代.从1960 年代至2000 年代,DIN、PO4-P 和SiO3-Si (从1980 年代)浓度分别从2.2±0.6μmol/L、0.14±0.03μmol/L、和2.4±1.1μmol/L 增加到21.1±11.3μmol/L、0.60±0.33μmol/L 和6.2±4.8μmol/L.

河流是物质从陆地向海洋输送的主要通道,河流入海的输水输沙量、海洋动力、地质构造与海面变化背景共同决定了河口和海岸的发育与演化,并对近岸海洋的生态系统健康和维持有重要意义.浙闽沿岸泥区位于东海陆架西部,总体平行于等深线,其动力系统受近岸、南向的苏北沿岸流-浙闽沿岸流及陆架、北向的台湾暖流控制.
