摘要
植物-土壤反馈作为植物分布、群落组成和演替的重要驱动力,近年来受到广泛关注。时空变异是驱动植物-土壤反馈效应的重要因素,但目前缺乏对其研究进展的梳理。该文综述了植物-土壤反馈时空变异的研究进展,并提出了未来可以继续深入的研究方向。在植物-土壤反馈时间尺度上,重点论述了植物不同发育阶段、实验周期与反馈效应的关系。在植物-土壤反馈的空间尺度上,重点讨论了植物空间分布及空间转移、土壤微生物类群及理化因子空间位置差异以及地上与地下系统对反馈系统的影响。基于研究进展,该文提出在反馈时间尺度上,需关注长期的、多点的动态反馈过程,提高反馈过程时间尺度上的分辨率;应充分考虑微生物类群与驯化和测试植物作用的缓冲时间,设置合理的驯化和反馈周期,让研究结果更为客观;在空间尺度上,需关注植物空间分布、土壤因子空间异质性以及地上和地下系统对反馈效应的影响,尽量做到接种土壤在物理结构上的相似性,以期获得更真实的反馈效应。
Plant-soil feedback(PSF),as an important driving force for plant distribution,community composition,and succession,has received extensive attention in recent years.The spatial-temporal variation are important factors driving PSF;however,there is currently a lack of review on its research progress.We summarized the research progress on the spatial-temporal variation of PSF and proposed research directions that could be pursued in the future.At the temporal scale of PSF,the relationships among plant developmental stages,experimental cycles,and feedback effects were emphasized.At the spatial scale of PSF,we focused on the spatial distribution and transfer of plants,the spatial differentiation of soil microbial communities and physicochemical factors,as well as the influence of above-and below-ground systems on PSF.Based on the research progress,we proposed to focus on the long-term,multi-point dynamic feedback to improve the temporal resolution of the feedback process.The buffering time of microbial communities on domesticated and tested plants needed to be considered,and reasonable domestication and feedback periods should be set to make the results more objective.At the spatial scale,the effects of plant spatial distribution,spatial heterogeneity of soil factors,and above-and below-ground systems on feedback effects should be paid attention.Efforts should be made to achieve similarity in the physical structure of the inoculated soil,in order to obtain more realistic feedback effects.
