| 摘 要： | 养分内循环是树木减少养分损失，提高养分利用效率的重要途径。树木细根寿命短、周转快．每年大量凋落死亡，因此，近20多年来树木细根养分内循环的研究逐渐受到人们的重视。关于树木细根养分内循环目前的研究结论比较复杂。本文从细根在树木地下部分养分内循环中的重要地位、细根养分内循环对树木减少养分损失的重要性、细根中各养分元素内循环的研究现状以及细根养分内循环研究方法存在的问题等方面综合论述了国内外的进展情况，并对今后的研究趋势进行了展望。

| Abstract: | Nutrient internal cycling plays an important role in reducing the nutrient loss while enhancing its use efficiency by trees. The fine root of trees is short in life but fast in turnover, and thus, the research of nutrient internal cycling in tree fine root has being recognized in recent two decades. This paper discussed the significance of nutrient internal cycling in tree fine mot, introduced the current situations of its research at home and abroad, and prospected its research trend in the future. |
