| 摘 要： | 用实验生态学方法研究了氮磷营养盐对近岸海洋硅藻组成的影响?结果表明，氮磷营养盐浓度及其比例可能对海水 游硅藻组成有着明显的影响，氮磷营养盐浓度越高，氮磷化离Ｒｅｄｆｉｅｌｄ比越远，硅藻种类越少，Ｓｈａｎｎｏｎ指数越低，这一结果在对虾养殖池浮游植物的观测中得到初步验证。

| Abstract: | Experiment was conducted to study the influence of N and P on population constiuent of planktonic diatoms in seawater.The concentrations of N and P and their ratios might significantly affect the population constituent of planktonic diatoms in seawater,the more the concentrations of N and P and the bigger the N/P ratio to Redfield ratio,the less the species of planktonic diatoms and Shannon's index.The experimental result was verified in the investigation from shrimp culturing ponds. |
