海洋初级生产力是海洋食物链的基础,是进行海洋生物资源评估和合理开发利用的基本依据。70年代在国际生物圈计划(IBP)的推动下,本领域的一些学者曾在世界各大洋的代表性海区进行过大量现场观测研究。最近,随着世界性的资源与环境问题的日趋严重,全球C循环已成为人们关注的研究课题。海洋初级生产力是了解全球C循环必不可少的指标之一,因而再度成为生物海洋学家的研究对象。新生产力是总初级生产力的一部分,亦是海洋N循环的特征参数,对于大洋水域而言,它反映了真光层生物群落的 The primary productivity of the oceans and seas is the basis of the marine food chain and is the basic basis for the assessment and rational development and utilization of marine living resources. Driven by the International Biosphere Program (IBP) in the 1970s, some scholars in the field conducted extensive field observations in representative sea areas around the world’s oceans. Recently, with the increasingly serious worldwide problems of resources and the environment, the global C-cycle has become a research topic of concern. Marine primary productivity is one of the indispensable indicators for understanding the global C cycle and thus has once again become the target of biological oceanographers. The new productivity is part of the total primary productivity and is also a characteristic parameter of the marine N cycle. For oceanic waters, it reflects the
