Micronutrient cycling in forest ecosystems is affected by soil conditions, litterfall turnover, throughfall properties, and some important ecological processes such as forest fire. This paper reviewed the related researches, with the focus on the micronutrient cycling in aboveground part of forest ecosystems and relevant affecting factors. In most forest ecosystems, litterfall and throughfall were the important sources ensuring the balanced supply of micronutrients for growth forest, while forest fire, environmental pollution, and fertilization could also play important roles in the micronutrient cycling in some forest ecosystems. Future studies on the micronutrient cycling in forest ecosystems should focus on the mechanisms governing micronutrient release from litterfall, the effects of global change and environmental pollution on the micronutrient cycling processes, and the balanced supply of micronutrients in restoration and reconstruction of degraded ecosystems.
森林生态系统中的微量养分循环受土壤条件、凋落物周转、穿透雨性质以及森林火灾等一些重要生态过程的影响。本文综述了相关研究,重点关注森林生态系统地上部分的微量养分循环及相关影响因素。在大多数森林生态系统中,凋落物和穿透雨是确保森林生长所需微量养分平衡供应的重要来源,而森林火灾、环境污染和施肥在某些森林生态系统的微量养分循环中也可能发挥重要作用。未来关于森林生态系统微量养分循环的研究应聚焦于凋落物中微量养分释放的调控机制、全球变化和环境污染对微量养分循环过程的影响,以及退化生态系统恢复和重建中微量养分的平衡供应。
