　　全球碳平衡中，土壤有机碳储量为2000 Pg，植被碳储量500 Pg，大气碳储量785 Pg，土壤中有机碳变化是影响大气温室气体含量的重要因素。中国人工林总量世界第一，可以通过造林树种的选择，增加森林土壤的碳汇功能，它主要通过4种机理来实现，包括稳定性有机-矿物复合体的形成、持久性封存的深层碳的增加、耐分解有机物成份的积累、以及土壤团聚体结构中碳的物理性保护。中国近年来对木材的需求上升，导致大量短轮伐期人工林的种植，采伐、火烧炼山、施肥与整地等营林措施对土壤碳汇功能形成重大影响。因而，通过加强对中国人工林土壤固碳机理的研究，通过人为措施实现具有较强固碳能力的森林类型，从而提高人工森林生态系统的固碳能力，它对中国减排增汇战略具有重要意义，而加强对不同营林措施对碳汇功能影响的研究是中国当前面临的重大课题。

In the global carbon balance, soil has a carbon stock of 2 000 Pg, with 500 Pg in vegetation and 785 Pg in the atmosphere. Soil plays a key role in regulating allocation of global carbon. China has largest area of plantation in the world. Proper selection of tree species could enhance ability of carbon sink in plantation soil, which is realized by 4 mechanisms:formation of organic-mineral complexation, long-standing sequestration in deep soil, recalcitrant organic component in litter and physical protection in soil aggregates. In recent years, China has great demand for timber, leading to expansion of short-rotation plantation. Logging, burning, fertilization land preparation could exert influence on carbon sink of soil. In this context, we could establish plantations of high carbon sequestration by comparing properties of soil organic carbon. Enhanced carbon sink in plantations will help in reducing potential of greenhouse effect. In this field, impact of plantation management strategies on soil carbon sink is urgently needed to be investigated.
