摘要: 全球气候变化和土地利用变化,体现了自然和人类活动对陆地生态系统的影响。造林,作为一种土地利用变化,能够改变陆地土壤碳储量。但其作用结果具有不确定性,受到多种因素的制约。本文对造林后土壤碳储量变化和影响这种变化的因素及其影响效果进行综述,介绍了土壤碳储量变化的研究方法,最后指出当前研究的不足和今后的努力方向。随着我国造林面积的扩大和人工林年龄的增加,加强造林后土壤碳积累机制及这种积累的空间分异和时间动态的研究,具有重要的政治意义和科学实践意义.

Abstract: Global climate change and land use change represent the influence of natural and human activities on terrestrial ecosystem.Afforestation,as a type of land use change,can change soil carbon storage.But the influence of afforestation on soil carbon storage is uncertain because it is controlled by a number of factors.The change of soil carbon storage after afforestation,the factors influencing this change and their impacts,and the methods used to study this change were summarized in this paper,with the shortcomings of current research and the direction for future effort given.With the expansion of afforestation area and the increase of plantation age,strengthening the plantation research of carbon accumulation mechanism and the spatial and temporal dynamic of carbon accumulation,will have important politic,scientific and practical significance in China.

Key words: Landscape fragmentation, Landscape dynamics, North Shannxi Loess Plateau
