海洋初级生产力的结构
焦念志, 王荣
中国科学院海洋研究所 青岛 266071
摘要:
海洋初级生产力的研究发展到今天,其内涵和信息已不是一个简单的量值所能表达得了的,必须建立起一个能够反映其生态学意义的关于生产力结构的概念。在这个概念中,初级生产力的结构归纳为以下4个方面: (1)组分结构,即不同类群生产者(包括自养微生物、各类浮游植物等)对初级生产力贡献的比例; (2)粒级结构,即不同粒径级(<2μm, 2 - 20μm, >20μm)生产者对初级生产力贡献的比例; (3)产品结构,即初级生产产品中颗粒有机碳(POC)和溶解有机碳(DOC)的分配比例; (4)功能结构,即新生产力占总初级生产力的比例。

THE STRUCTURE OF MARINE PRIMARY PRODUCTIVITY

Abstract:
Great progresses have been made in the field of marine primary productivity study during the past years. At the present time, it seems to be essential to study the primary productivity not only by measuring its magnitude but also by studying its structure if we are to have a good understanding of the energy flow of a marine pelagic ecosystem. The “structure” includes. four categories: 1. the component structure — contributions of different producers (phytoplankton, autotrophic bacteria); 2, the particle size structure — contributions of different size grades (pico-, nano-, and netp1ankton); 3. the products structure — the ratio of photosynthetically produced POC to DOC; 4. the function structure — the ratio of new production to regenerated production.
Key words:  Primary productivity/production, Marine ecology, Phytoplankton, New production
