Plant-soil feedbacks (PSFs) are interactions among plants, soil organisms, and abiotic soil conditions that influence plant performance, plant species diversity, and community structure, ultimately driving ecosystem processes. We review how climate change will alter PSFs and their potential consequences for ecosystem functioning. Climate change influences PSFs through the performance of interacting species and altered community composition resulting from changes in species distributions. Climate change thus affects plant inputs into the soil subsystem via litter and rhizodeposits and alters the composition of the living plant roots with which mutualistic symbionts, decomposers, and their natural enemies interact. Many of these plant-soil interactions are species-specific and are greatly affected by temperature, moisture, and other climate-related factors. We make a number of predictions concerning climate change effects on PSFs and consequences for vegetation-soil-climate feedbacks while acknowledging that they may be context-dependent, spatially heterogeneous, and temporally variable.
植物-土壤反馈(PSFs)是植物、土壤生物和非生物土壤条件之间的相互作用,它们影响植物的表现、植物物种多样性和群落结构,最终驱动生态系统过程。我们回顾了气候变化将如何改变 PSFs 及其对生态系统功能的潜在影响。气候变化通过相互作用物种的表现以及物种分布变化导致的群落组成改变来影响 PSFs。因此,气候变化通过凋落物和根分泌物影响植物对土壤子系统的输入,并改变与共生体、分解者及其天敌相互作用的活植物根系的组成。这些植物-土壤相互作用中有许多是物种特异性的,并且受温度、水分和其他与气候相关的因素的极大影响。我们对气候变化对 PSFs 的影响以及对植被-土壤-气候反馈的后果做出了一些预测,同时承认这些影响可能依赖于背景、空间异质性和时间变化。
