Research Progress on Quantifying the Influence of Fire Disturbance on Forest Carbon Sink

火干扰是森林生态系统的主要干扰因子之一,会对森林碳储量和碳动态产生重要影响。准确量化火干扰对森林中各碳库的影响程度,对国家及全球碳预算具有重要意义。文中对国内外火干扰下森林碳储量的研究现状、研究方法和研究内容进行了综述。大量研究表明,燃烧效率、火烧烈度等关键因子的准确量化是精确估算火干扰对森林碳储量影响的基础,火烧样地调查与遥感反演法和模型模拟法的综合运用有利于精确量化火干扰下的森林碳库,各种火烧数据源的同化处理是准确揭示火干扰对森林碳库影响的重要保证。在此基础上,提出一些更加准确量化火干扰对森林碳储量影响的研究途径,并对未来的研究方向进行了展望。

Fire disturbance, one of the principal interferential factors to forest ecosystem, has a significant impact on forest carbon storage and dynamics. Accurate quantification of the influence of fire disturbance on forest carbon sinks is of great importance to national and global carbon budget. This article reviewed the research state, methods and contents at home and abroad of forest carbon storage under fire disturbance advances. The numerous researches indicated that the accurate quantification of key factors including combustion efficiency and fire severity is fundamental to estimate precisely the influence of fire disturbance on forest carbon storage; the comprehensive utilization of fire sample plot survey, remote sensing inversion method and model simulation method help quantify precisely forest carbon sinks under the interference of fire; assimilation processing of various fire data is an important guarantee to indicate fire disturbance influence on forest carbon sinks. Based on the above results, some research approaches were proposed for more accurate quantification of the effect of fire disturbance on forest carbon storage, and the future research direction were prospected.
