不同乔木树种根系养分吸收策略的维度性差异

Dimensional Differences in Nutrient Uptake Strategies of Roots of Different Tree Species

乔木细根在森林生态系统养分循环中扮演着重要的角色。在长期的进化过程中,不同地区的根系为了适应环境形成复杂的形态结构、化学组分和共生关系,导致了不同的养分吸收策略。本文综合前人的研究结果,对不同温度带的1~5级细根的形态结构、化学组分和共生菌根类型特征进行分析,从而总结预测不同温度带根系养分吸收策略以及指出地下根系生态学未来可能的研究方向。

Fine roots of trees play an important role in nutrient cycling of forest ecosystems.In the long-term evolutionary process,the roots in different regions formed complex morphological structures,chemical components and symbiotic relationships in order to adapt to the environment,resulting in different nutrient absorption strategies.Based on the previous research results,this paper analyzes the morphological structure,chemical components and symbiotic mycorrhizal type characteristics of 1~5 fine roots in different temperature zones,so as to summarize and predict the nutrient absorption strategies of roots in different temperature zones and point out the possible research direction of underground root ecology in the future.
