| 摘 要： | 采用室内营养加富法研究了2008年流沙湾春季和夏季营养限制状况.结果表明,春季和夏季N、P、Si、Fe等单营养添加缸浮游植物均无显著的促进效应,与对照差异不显著;而N、P和N、P、Si多营养添加缸均显著促进了浮游植物的增长.其中春季N、P缸和N、P、Si缸浮游植物叶绿素a最大生物量分别为49.9 mg/m3和38.4 mg/m3,夏季N、P缸和N、P、Si缸叶绿素a最大生物量分别达14.2 mg/m3和49.4 mg/m3.N、P协同限制流沙湾浮游植物生长;流沙湾大规模高密度贝类养殖导致的营养沉降作用和大型藻类和海草类生物代谢作用可能是造成流沙湾浮游植物营养限制的主要因素.流沙湾浮游植物受到养殖贝类高摄食压力及海域低营养供给共同作用,导致生态系统结构不平衡.

| Abstract: | Nutrient limitation of phytoplankton was studied in the water collected from Liusha Bay in spring and summer of 2008 by indoor nutrient addition experiments.The results showed that there was no significant promotion between the control and the single nutrient addition treatment of nitrogen,phosphorus,silicon and iron in both spring and summer;but multiple nutrient addition treatment of nitrogen,phosphorus and nitrogen,phosphorus plus silicon significantly promoted the growth of the phytoplankton,the maximal... |
