中文摘要 土壤活性有机碳作为森林土壤有机碳的活跃成分，在凋落物分解和土壤碳循环中发挥着重要作用。林火干扰通过改变土壤底物的数量和理化性质进而影响土壤活性有机碳，因而阐明林火干扰对土壤活性有机碳的影响是开展森林碳循环研究的基础。文中以6种土壤活性有机碳为研究对象，分别阐述林火干扰对土壤活性有机碳影响的研究进展。针对目前研究现状及存在问题，认为应进一步深化探究林火干扰后土壤微生物活性变化机制对土壤活性有机碳的影响，揭示土壤碳库平衡的影响机理；加强林火干扰后C-N耦合循环特征的研究；深入研究林火干扰后影响土壤活性有机碳的内在因素和外在因素的相互作用，综合评价林火干扰对土壤活性有机碳的短期与长期影响；加强林火干扰—土壤碳库—全球气候变化的交互关系研究，深入探讨林火干扰与土壤活性有机碳的相互作用关系及影响机理。

英文摘要 As an active component of soil organic carbon, soil labile organic carbon plays an important role in litter decomposition and soil carbon cycle. Forest fire disturbance affects soil labile organic carbon by changing the quantity and physicochemical properties of soil substrates. Thus clarifying the impact of forest fire disturbance on soil labile organic carbon is the basis for carrying out the carbon cycle of forest ecosystems. With an eye on 6 components of soil labile organic carbon, this paper elaborates the research progress in the effect of forest fire disturbance on soil labile organic carbon. Based on the current research and existing problems, it is argued that further research should be made to explore the effects of forest fire disturbance on soil microbial activity change regime to reveal the influence mechanism of soil carbon pool balance, enhance the characteristics of C-N coupling cycle after fire interference, understand the interaction between the internal and external factors affecting soil labile organic carbon after forest fire disturbance to comprehensively evaluate the short-term and long-term effects of forest fire disturbance on soil labile organic carbon, and strengthen the study of interaction between forest fire disturbance, soil carbon pool and global climate change to have in-depth discussion on the interaction between forest fire disturbance and soil labile organic carbon and its influence mechanism.
