海洋浮游生物的生态化学计量学研究进展

生态化学计量学可以简单定义为从分子到生物圈的元素生物学，其跨越了环境和生命的各个层次，是构建从分子到生态系统统一化理论的新思路，是生态科学发展的必然趋势.海洋生物占地球生物圈总生物量的50%，是全球生物地球化学循环的重要组成部分，而浮游生物作为海洋生态系统物质循环和能量流动的重要环节，在海洋生态系统元素循环过程中起着关键作用.但是目前关于海洋浮游生物生态化学计量学的研究较零散和缺乏.因此，本文从限制元素影响海洋浮游生物的生态现象和机理、生化物质对营养限制的响应、营养限制的食物链传递与反馈4方面，对海洋浮游生物化学计量学研究进行综述，分析了该领域当前存在的问题，并对我国海洋浮游生物生态化学计量学研究的发展重点提出了展望.

Research advances in ecological stoichiometry of marine plankton.

Ecological stoichiometry can be simply defined as: The biology of elements from molecules to the biosphere, which spans all levels of the environment and of the life. It’s a new idea to build a unified theory and becomes an inevitable trend to develop the ecological science. Marine ecosystems, which contribute to 50% of the biosphere biomass, are the important component of the global biogeochemical cycles. Marine zooplankton plays an important role in the material circulation and energy flow of marine ecosystems and serves as a connecting link between the preceding and the following in a more precise understanding of the key elemental cycles. However, research on ecological stoichiometry of marine plankton is fragmentary and rare. This article summarized the ecolo gical phenomena and mechanisms of limiting elements affecting marine plankton, the response of biochemical substances to nutrition limitation, and the food chain transmission and feedback of nutrition limitation. Meanwhile, we also put forward some perspectives for future research of ecological stoichiometry of plankton in China’s seas.
