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浮游硅藻组成有着明显的影响 ,氮磷营养盐浓度越高 ,氮磷比离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 .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.
