Forest soil organic carbon is an important component of global carbon cycle, and the changes of its accumulation and decomposition directly affect terrestrial ecosystem carbon storage and global carbon balance. Climate change would affect the photosynthesis of forest vegetation and the decomposition and transformation of forest soil organic carbon, and further, affect the storage and dynamics of organic carbon in forest soils. Temperature, precipitation, atmospheric CO2 concentration, and other climatic factors all have important influences on the forest soil organic carbon storage. Understanding the effects of climate change on this storage is helpful to the scientific management of forest carbon sink, and to the feasible options for climate change mitigation. This paper summarized the research progress about the distribution of organic carbon storage in forest soils, and the effects of elevated temperature, precipitation change, and elevated atmospheric CO2 concentration on this storage, with the further research subjects discussed.
森林土壤有机碳是全球碳循环的重要组成部分,其积累和分解的变化直接影响陆地生态系统碳储量和全球碳平衡。气候变化会影响森林植被的光合作用以及森林土壤有机碳的分解和转化,进而影响森林土壤中有机碳的储存和动态变化。温度、降水、大气二氧化碳浓度等气候因素均对森林土壤有机碳储量有着重要影响。了解气候变化对该储量的影响有助于森林碳汇的科学管理以及减缓气候变化的可行选择。本文综述了森林土壤有机碳储量分布以及温度升高、降水变化和大气二氧化碳浓度升高对该储量影响的研究进展,并讨论了进一步的研究主题。
