摘要: 蚂蚁作为生态系统的消费者和分解者,其对土壤有机碳库的影响一直是学术界研究的热点。目前研究主要从蚂蚁对土壤宏量元素储量、理化性质、微生物群落活动等方面探究蚂蚁对土壤有机碳库的影响。本文综述了蚂蚁扰动对土壤有机碳循环过程特征的影响。蚂蚁筑巢改变了蚁穴土壤的微生境、微气候与土壤理化性质,并通过重构土壤微生物群落结构特征、调控地表植被演替过程与格局等方式,直接或间接的影响蚁巢中土壤有机碳来源、碳库分配过程、有机碳库稳定性、有机质微观分子特征等,在微域、局地乃至景观尺度上影响土壤有机碳的循环过程。未来研究应着重从量化蚂蚁扰动及其导致的环境因子波动对土壤碳通量变化的贡献、建立定量模型联系并统一蚂蚁影响下土壤碳循环过程、厘清蚂蚁影响土壤有机碳库稳定性的机制等方面开展深入研究,揭示蚂蚁作为“生态工程师”在调控土壤碳循环过程中的作用机制。

Abstract: The impact of ants, as consumer and decomposer in ecosystems, on soil organic carbon pool is a hotspot in soil fauna research. Recently, effects of ants on soil organic carbon pool dynamics have been mainly documented in terms of soil macro-elements storage, physical and chemical properties, and microbial community. We summarized the effects of ant disturbance on soil organic carbon cycle. Ant nesting alters microhabitat, microclimate, and physicochemical properties of ant nested soils. By re-shaping soil microbial community structure, regulating the succession process and pattern of vegetation, ant nesting directly or indirectly affects the source, allocation, stability, and microcosmic molecular characteristics of soil organic carbon, scaling from micro, local, to landscape scale. In the future, more attentions should be paid on quantifying the contribution of ant disturbance combined with the fluctuations in environmental factors to soil carbon flux dynamics, establishing quantitative model to link and unify ant-induced soil carbon cycle process, and clari-fying mechanisms underlying the impacts of ants on the stability of soil organic carbon pool, and finally revealing the “ecological engineers” role of ants in regulating soil organic carbon cycling.

Key words: ants, soil organic carbon, heterogeneity, mineralization, microorganisms.
