摘  要:
森林土壤有机碳(SOC)对全球碳循环有着重要的作用,森林SOC积累和分解直接影响陆地生态系统碳存储和全球碳平衡。碳汇的基本策略是把CO2固定于植被体,削减温室气体的排放量。森林经营管理对土壤碳库固定与存储影响明显且持续时期较长。鉴于此,综合分析了森林收获、轮伐期、氮肥施入、树种等营林措施对土壤碳库变化的影响及其不确定性,指出了当前森林土壤有机碳研究面临的一些问题和今后的研究方向。

摘  要:
Forest soil organic carbon(SOC) 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.Forestry can generate a sink for greenhouse gases.Afforestation is a common strategy that leads to the incorporation of carbon dioxide(CO2) in plant biomass.Adapted management of existing forests may have a less obvious or slower effect on the terrestrial C pool.It is mainly relevant in countries that already have a large forest cover.This paper reviewed soil organic carbon was affected by harvesting,rotation,thinning,fertilizer application and tree-species selection,which have an impact on the forest productivity and consequently on C sequestration in the ecosystem.Some related issues and further research directions were discussed.
