摘要:

全球气候变化和土地利用变化影响着陆地碳源/汇的变化。造林作为一种土地利用变化,可以增加陆地碳汇,减缓大气中CO2的积累。文中首先对陆地碳汇及其形成原因进行综述,肯定了造林在陆地碳汇中的重要作用,然后阐述了造林对陆地碳汇的影响途径、造林后植被碳和土壤碳的变化及相互联系,并对全球造林活动对陆地碳汇贡献潜力作简要介绍,最后指出当前研究中的不足及今后的努力重点。造林是重要的临时陆地碳库,加强对造林碳汇的客观研究,对我国具有重要的政治意义和科学实践意义。

Abstract:

The terrestrial carbon source or sink was influenced by global climate change and land use change. Afforestation, as a type of land use change, can add terrestrial carbon sink and alleviate atmospheric CO2 increment, which was recognized as a counteract measure to the national GHGs emission by internationals and governments. Study on the influence of afforestation on terrestrial carbon sink has become one of the research hotspots in global change and forestry practice. Terrestrial carbon sink and its source were summarized firstly in the paper and the importance of afforestation on terrestrial carbon sink was affirmed. Then the influencing approach of afforestation on terrestrial carbon sink, the change of vegetation and soil carbon and their relationship after afforestation was discussed, and the potential of global afforestation on terrestrial carbon sink was presented. Finally, the shortage of current research and the emphases of future research were given. China has the largest plentation area, with nearly one third of the global total, strengthening the objective research of afforestation and its terrestrial carbon sink, will have an important politic, scientific significance in China.

Key words: afforestation, plantation, soil carbon, terrestrial carbon sink, vegetation carbon
