森林土壤黑碳:功能、储量和测定方法

Black Carbon in Forest Soils:Functions,Reserves and Determining Methods

土壤黑碳化学性质稳定,不易分解,在长期时间尺度上具有重要的固碳作用。由于每年都有大面积的天然森林火灾和人为用火的发生,在全球森林生态系统中,形成了大量的土壤黑碳。相对于大气、农业土壤黑碳研究,森林土壤黑碳的研究工作起步晚,个案研究数据较少,影响着我们在区域和全球尺度上对森林碳汇功能的准确评价,也影响着对森林土壤黑碳生态功能的了解。在综述相关文献的基础上,本文介绍了目前世界上森林土壤黑碳的主要研究结果、研究方法以及在我国的研究现状,以便促进我国森林土壤黑碳领域工作的深入开展。

Soil black carbon （SBC） plays an important role in long-term carbon sequestration due to its chemically stable feature. Every year there are a large number of natural and man-induced forest fires, resulting in black carbon in the global forest ecosystems. Relative to the studies on SBC in agricultural soils, the investigations on SBC in forest soils were later conducted and the number of case studies of SBC in forest soils is fewer. This impacts our accurate assessment on the roles of SBC both for sequestrating carbon at regional and global scales and playing ecological functions. In this review on the basis of the updated literature, we made an introduction to main findings, methodology employed and the state-of-art of SBC studies in China in order to in the field of SBC studies in forest ecosystems.
