摘  要：
近岸海域的富营养化是被广泛关注的重要海洋生态环境问题,其中N和P是富营养化过程主要的2种营养盐。本实验旨在探讨N和P对缘管浒苔的生长、光合作用以及可溶性蛋白含量的影响。结果表明:添加N和P都显著增加藻体的光合作用速率、可溶性蛋白含量,最终显著提高藻体的相对生长率。缘管浒苔对N和P的利用可以在一定范围内相互弥补。这表明缘管浒苔可以更为有效的在富营养化海区生长,从而成为大规模"绿潮"发生的潜在种类。

摘  要：
The ongoing coastal eutrophication is becoming one of the major questions of marine environment with widespread concern,and N and P are the two main nutrients which result in eutrophication.In this experiment investigation of the effects of N and P on the growth,photosynthesis and soluble protein of Enteromorpha linza were carried out.The results showed that N and P added in natural sea water could increase the net photosynthetic rates and the concentrations of soluble protein,as a result significantly improved the growth rates of the thalli.In normal sea waters,the concentrations of N and P are always so low that they could become the limiting factors;according to our research,they could make up for a deficiency of each other in certain range.It indicated that Enteromorpha linza could grow more effectively in eutrophic sea areas,thereby it turns into one of the potential species which cause large-scale occurrence of green macro-algal blooms.
