摘要/Abstract

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.

关键词: 浮游硅藻, 营养盐, 种群组成, 氮, 磷

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.

Key words: Planktonic diatoms, Nutrients, Population constituent, Nitrogen, Phosphorous
