生物炭的稳定性及其对土壤温室气体排放影响的研究进展

Research Progress of Biochar Stability and Effects on Soil Greenhouse Gas Emission

如何减少温室气体排放、增加陆地生态系统碳汇是缓解当前气候变化的热点研究之一。生物炭可为解决这一问题提供新的途径。基于生物炭作为一种固碳措施的有效性,概述了生物炭的特性、降解以及其施用对土壤温室气体排放的影响方面的研究进展,以期正确评估生物炭的固碳减排效应。

How to reduce greenhouse gas emissions and increase the terrestrial ecosystem carbon sequestration is one of the hot spot of research to alleviate the current climate change. Biochar has emerged as a potential strategy for climate change mitigation. Based on the effectiveness of bioehar as a carbon measures, the research progress of biochar characteristics and decomposition, its influence on soil greenhouse gas production were reviewed, so as to accurately evaluate carbon fixation and emission reduction of biochar.
