海洋中哪一种营养盐是限制因子抑或刺激因子 ,众多学者各有说法。一般认为 ,开阔大洋为氮限 ,近海为磷限制 ,个别海区有硅限制 ;在高营养盐、低叶绿素海区有铁限制。本文作者提出自己的见解 :铁是刺激因子 ,不是限制因子 ;许多海域硅是主要限制因子。为了活跃学术争鸣和讨论 ,本刊编发了此文 ,希望不同学术见解者能参与研讨。用作者自己的话说 ,叫“抛砖引玉”。
Which nutrients in the ocean is a limiting factor or stimulating factor, many scholars have their own arguments. It is generally accepted that open ocean is nitrogen limit, offshore limit is phosphorus limit, and individual sea limit is silicon limit. There is iron restriction in high nutrient salt and low chlorophyll sea area. The authors put forward their own opinion: iron is a stimulus, not a limiting factor; many sea areas of silicon is the main limiting factor. In order to actively academic debate and discussion, this issue of this article compiled, hope that different academic insight can participate in the discussion. In the author’s own words, called “initiate.”
