摘要：森林是陆地生态系统的主体,是陆地上最大的碳储库和碳吸收汇。国内外研究表明,土壤亚系统在调节森林生态系统碳循环和减缓全球气候变化中起着重要作用。但是,由于森林类型的多样性、结构的复杂性以及森林对干扰和变化环境响应的时空动态变化,至今对森林土壤碳储量和变率的科学估算,以及土壤关键碳过程及其稳定性维持机制的认识还十分有限。综述了近十几年来我国森林土壤碳储量和土壤碳过程的研究工作,主要包括不同森林类型土壤碳储量、土壤碳化学稳定性、土壤呼吸及其组分、土壤呼吸影响机制、气候变化与土地利用对土壤碳过程的影响等;评述了土壤碳过程相关科学问题的研究进展,讨论了尚未解决的主要问题,并分析了未来土壤碳研究的发展趋势,以期为促进我国森林土壤碳循环研究,科学评价森林土壤碳固持潜力及其稳定性维持机制和有效实施森林生态系统管理提供科学参考。
Forests,as a principal component of terrestrial ecosystems,are the largest carbon（C） pool and C sink.The extensive studies over the past decade indicate soil subsystem plays an important role in regulating forest ecosystem C cycling and mitigating global climate change.However,the scientific estimations of forest soil C stock and variability are inadequate,and the understanding of the key C processes and mechanism underlying soil C stability is still limited,due to the diversity of forest types,the complexity of forest structure and the temporal and spatial dynamic variations of responses of forests to disturbances and environmental changes.In this paper,we synthesize findings from published studies in recent ten years on forest soil C stock and soil C process in China,including soil C stocks in different forests,soil C chemical stability,soil respiration and its portioning components in association with underlying mechanisms,and impacts of climate changes and land use change on soil C processes,etc.The research progress of key scientific issues related to soil C processes and the principal unresolved issues are explored.We also discuss the future development of forest soil C research in China in view of the global perspective.The review is expect to provide scientific contributions for understanding forest soil C sequestration potential and for developing adaptation measures in forest management based on the current forest soil C research progress in China.
