微量元素对浮游植物生理作用的研究进展

Review of Progress on the Physiological Effects of Micronutrients on Phytoplankton Physiology

浮游植物对于全球初级生产力的贡献显著,为海洋和淡水的水生态系统提供了能量基础。浮游植物的生长受到一系列生物和非生物的因素影响,比如营养盐浓度、温度和捕食作用等。因此浮游植物显著影响着水生态系统的各项功能实现。尽管国内外的许多研究指出,除了氮磷元素之外,不同的微量元素不同程度地影响着浮游植物的生理过程,但是当前对于众多微量元素对于不同种类的浮游植物的作用仍缺少一个系统的认识。文章梳理了关于浮游植物的相关研究报道,总结了不同的微量元素对于不同的浮游植物的生长和生理学的影响,为全面认识浮游植物的生理特征以及对于环境中各类元素的含量变化的响应机制提供了参考。

Phytoplankton contribute signif icantly to global primary productivity,providing an energy basis for marine and freshwater aquatic ecosystems.The growth of phytoplankton is influenced by a series of biological and non-biological factors,such as nutrient concentrations,temperature,and predation.Therefore,phytoplankton signif icantly affect the realization of various functions in aquatic ecosystems.Although many studies at home and abroad have pointed out that besides nitrogen and phosphorus elements,different micronutrient affect the physiological processes of phytoplankton to varying degrees,there is still a lack of a systematic understanding of the effects of numerous micronutrients on different types of phytoplankton.This paper reviews the relevant research reports on phytoplankton and summarizes the impacts of different micronutrient on the growth and physiology of different phytoplankton,and provides a reference for comprehensively understanding the phytoplankton physiology and their response mechanisms to changes in the content of various elements in the environment.
