中文摘要: 森林生态系统土壤有机碳作为陆地碳循环研究的重要内容,在全球变化和全球碳收支的研究中占据了重要地位。火干扰能改变森林生态系统中土壤与大气的碳素交换,是森林生态系统碳循环的重要影响因子。为此,加强火干扰下森林生态系统土壤有机碳循环研究,了解火干扰与森林生态系统土壤有机碳循环之间的交互关系,有助于揭示火干扰下土壤碳库动态机理。本研究简要综述了火干扰对森林生态系统土壤有机碳影响研究进展,探讨了不同强度林火对土壤有机碳的影响,分析了其产生机理;阐述了火干扰不同时间后土壤有机碳变化、火干扰对不同土层土壤有机碳的影响,并分析了其原因。最后讨论了火干扰对森林土壤有机碳影响研究中存在的相关问题,提出了在今后研究中应关注的问题,并对未来的研究方向进行了展望。
英文摘要: Soil organic carbon in forest ecosystems is important in the terrestrial carbon cycle, occuping an important position in the global carbon budget and global change. Fire disturbance is an important factor which affects carbon cycling, changing carbon exchange between soil and atmosphere in forest ecosystems. Therefore, strengthening soil organic carbon cycling research under the fire disturbance in forest ecosystems, understanding interactions between fire disturbance and soil organic carbon cycling, those could help to reveal the dynamic mechanism of soil carbon pools under the fire disturbance. This paper reviewed the research progress on the fire disturbance on soil organic carbon in the forest ecosystem, and discussed the influence of different intensities of forest fire disturbance on soil organic carbon, and analyzed its generating mechanism. In addition, the change and its influence factor of soil organic carbon during different fire disturbance periods and the influence of fire disturbance on the soil organic carbon in different soil layers was also discussed. Finally, we dicussed the related issues in forest soil organic carbon research that should be paid more attention in future, and looked forward to the future research direction.
