| 摘 要： | 根据2006-07～2007-10 4个航次的调查资料,分析讨论了春、夏、秋、冬四季北黄海营养盐结构分布变化特征及营养盐限制状况.结果表明:春夏季表层,10 m层N/P,Si/N和Si/P值分布变化较大,呈现辽东半岛和山东半岛近岸高中部海域低的分布态势,高值区分别自鸭绿江口和夹河河口向外扩散,且均高于Redfield比值.秋冬季表层N/P,Si/N和Si/P值明显降低,且分布变化不大.10 m层,底层各季节分布相近,高值区位于鸭绿江口和夹河口附近.营养盐结构的分析表明,北黄海海域春夏季大部分站位表层浓度低于浮游植物生长的最低阈值,且春、夏、秋三季主要是受P的潜在限制,冬季营养盐限制状况消失.

| Abstract: | The distribution features of nutrient structure and nutrient limitations in the north of Yellow Sea were discussed based on the data collected from July 2006 to October 2007.The results showed the ratios of N/P,Si/N and Si/P changed much larger in the surface water and 10 m,and lower in the middle sea,higher in the area of liaotung peninsula and Shandong peninsula in spring and summer.The high values was diffused from Yalv river mouth and Clip river estuary,and all much higher than Redfield ratios.The ratio... |
