二营养素的来源和意义,氮并且磷,我们由一个修改冲淡方法的 reinvestigated 从 Jiaozhou 海湾表现在海水样品上,在秋天 2004。这个修改冲淡方法说明了微浮游动物通过矿化作用供应的浮游植物生长率,微浮游动物放牧死亡率,内部、外部的滋养的水池,以及营养素。结果显示浮游植物网生长率从在海湾内接着增加了,到在海湾外面,到在 theXiaogang 港口。擦伤死亡率的浮游植物最大值生长率和微浮游动物是 1。14 和 0.92 d~( 在海湾外面的 -1) , 0.42 和 0.32 d~( 在海湾内的 -1) 并且 0.98 和 0。62d ~( 在港口的 -1) 分别地。在海湾外面,重新使矿物化的氮(K_r = 24.49 ) 对浮游植物的生长的有的重影响。在海湾内,重新使矿物化的磷(K_r=3.49 ) 强烈影响了浮游植物生长。在港口,重新使矿物化的磷(K_r=3.73 ) 在由浮游植物生长的更大的需求。结果证明为浮游植物生长供应的不同营养素水池是根据浮游植物,社区极大地组织,微浮游动物放牧死亡率和环境条件。比以前相信,滋养的矿化作用才为在 theJiaozhou 海湾的浮游植物生长是更重要的。
The source and significance of two nutrients, nitrogen and phosphorous, were investigated by a modified dilution method performed on seawater samples from the Jiaozhou Bay, in autumn 2004. This modified dilution method accounted for the phytoplankton growth rate, microzooplankton grazing mortality rate, the internal and external nutrient pools, as well as nutrient supplied through remineralization by microzooplankton. The results indicated that the phytoplankton net growth rate increased in turn from inside the bay, to outside the bay, to in the Xiaogang Harbor. The phytoplankton maximum growth rates and microzooplankton grazing mortality rates were 1.14 and 0.92 d^-1 outside the bay, 0.42 and 0.32 d^ -1 inside the bay and 0.98 and 0.62 d^-1 in the harbor respectively. Outside the bay, the remineralized nitrogen (Kt = 24.49) had heavy influence on the growth of the phytoplankton. Inside the bay, the remineralized phosphorus(Kt = 3.49) strongly affected the phytoplankton growth. In the harbor, the remineralized phosphorus (Kt = 3.73) was in larger demand by phytoplankton growth. The results demonstrated that the dif- ferent nutrients pools supplied for phytoplankton growth were greatly in accordance with the phytoplankton community structure, microzooplankton grazing mortality rates and environmental conditions. It is revealed that nutrient remineralization is much more important for the phytoplankton growth in the Jiaozhou Bay than previously believed.
