摘  要:
由于生物质炭的碳化学结构主要以芳香碳为主,具有高度的生物化学和热稳定性,可长期保存于土壤中而不被土壤微生物所分解,因此其在增加土壤碳库容量、稳定土壤有机碳库以及维持土壤碳平衡方面发挥着重要作用。本研究综述了生物质炭输入对活性有机碳、腐殖质特性以及有机碳矿化特征的影响,较详细地分析了生物质炭输入对土壤CO_2通量的影响效果及其机制,最后展望了该方向今后的研究重点。

摘  要:
Biochar has a character of high biological,chemical and thermal stability,due to most of its C chemical structure presenting in the form of aromatic C,and consequently it can not be easily decomposed by soil microorganisms and can be preserved in the soil for a long-term period.Therefore,it plays an important role in the aspects of the capacity and stability of soil organic carbon pool and maintaining soil carbon balance.The responses of soil labile organic carbon,soil humic substances and soil organic carbon mineralization to the application of biochar and the influcing mechanism of biochar on soil CO_2 emission were studied.Finaly,the focuses in this field for future study were put forward.
