摘要:

森林土壤有机碳是陆地生态系统碳库的重要组成部分,其变化关系到生态系统碳平衡和气候变化应对能力。抚育间伐作为重要的森林经营措施,可通过调节林分结构、微环境条件和植物?微生物互作过程,影响土壤有机碳的输入、转化与稳定。近年来,国内外学者围绕抚育间伐对森林土壤有机碳的影响开展大量研究,但相关认识仍较分散。本研究系统梳理不同间伐强度、恢复阶段和森林类型下土壤有机碳的响应特征及其调控机制。轻度间伐对土壤有机碳含量和碳储量的影响通常不显著,中度间伐总体上有利于土壤有机碳含量和碳储量的积累,重度间伐则可能导致土壤有机碳含量和碳储量增加或减少。间伐后短期内土壤有机碳含量和碳储量多呈下降趋势,中长期则表现为持续增加或逐渐趋于新的稳态。针叶林和针阔混交林土壤有机碳含量和碳储量对间伐的响应多表现为增加或无显著变化,而阔叶林则可能表现为增加、减少或无显著变化。这些差异主要与间伐对森林土壤碳输入和碳输出过程的综合调节有关。未来,应加强长期定位观测与模型研究的结合,优化不同立地和经营条件下的间伐措施设计,并深化土壤碳汇功能与生态系统多功能性的耦合研究,以进一步揭示间伐影响森林土壤有机碳的作用机制。

Abstract:

Forest soil organic carbon is an important component of the terrestrial ecosystem carbon pool, and its dynamics are closely linked to the ecosystem carbon balance and the response capability to climate change. As an important forest management practice, thinning can influence the input, transformation, and stabilization of soil organic carbon by altering stand structure, microenvironmental conditions, and plant-microbe interactions. In recent years, a large number of studies have examined the effects of thinning on forest soil organic carbon, but the relevant knowledge remains scattered. This review systematically summarizes the response patterns of soil organic carbon under different thinning intensities, recovery stages, and forest types, as well as the underlying regulatory mechanisms. Existing studies show that light thinning generally has little effect on soil organic carbon content and stock, moderate thinning is overall conducive to the accumulation of soil organic carbon content and stock, whereas heavy thinning may either increase or decrease soil organic carbon content and stock. In the short term after thinning, soil organic carbon content and stock often decline, whereas over the medium to long term they tend to increase continuously or gradually approach a new stable state. In coniferous forests and coniferous-broadleaf mixed forests, soil organic carbon content and stock usually increase or show no significant change following thinning, whereas in broadleaf forests they may increase, decrease, or remain unchanged. These differences are mainly related to the combined regulation of carbon input and output processes in forest soils following thinning. Future research should strengthen the integration of long-term field observations with modeling, optimize thinning regimes under different site and management conditions, and deepen research on the coupling between soil carbon sequestration and ecosystem multifunctionality, so as to better clarify the mechanisms by which thinning affects forest soil organic carbon.
