摘要
具有生物活性的元素Fe被认为限制了海洋生物生产力,其在海洋生态系统中的生物地球化学循环对全球碳循环起到调节作用,全球40%～50%的海洋因"高叶绿素低营养盐"(HNLC)"缺Fe"而初级生产力较低。然而,关于生物活性元素Fe的研究不仅涉及海洋科学,还与大气科学、环境科学、地球科学等学科紧密联系。近些年,围绕生物活性元素"Fe"开展的研究不仅是地球科学领域的前沿问题,还是海洋学家与环境学家共同关注的热点问题。目前,尽管对于生物活性元素Fe的研究已取得很大的进展,但模型、室内实验及野外观测之间仍存在很大的挑战与不确定性。系统地总结了生物活性元素Fe最重要的自然来源方式,详细介绍了影响生物活性元素Fe溶解度的主要因素,最后,对将来的工作提出建议,为我国未来开展类似的研究提供参考。
In the marine ecosytem bioavailability iron （Fe） is one of the most important mieronutrient for the marine primary productivity. It plays an important role in the global biogeoehemieal cycles and the carbon cycle. About 40% - 50% of the total surface ocean is High Nutrient Low Chlorophyll （HNLC） owing to limiting of bioavailability Fe. However, research on bioavailability Fe not only involves in the discipline of ocean science, but also has a close connection with atmosphere science, environment science, geoscienee, etc. In recent years, the research on it is considered as one of the most important scientific problems in Earth science system and attracts extensive concerns from the oceanographers and environmentalists. However, there are still lots of challenges and uncertainties existing in models, experiments and field observations. Due to the complicated Fe in dust, we only summarize the natural sources of bioavailability Fe and detailed influence factors of bioavailability Fe solubility in this review. Finally, we come up with the suggestions and reference for our future work.
