摘　　要：通过造林和再造林,增加森林碳汇量是目前公认最经济有效地解决CO2浓度上升的方法之一,人工林的碳汇作用也被认为是减缓全球气候变化的一种可能机制和最有希望的选择。根据国内外植树减排的计算规则,结合干旱区自然环境特征,提出了干旱区规模化植树CO2减排效果的计算方法,对植树减排计算因子的获取方法进行了探讨,指出应从政策、技术、市场等各个方面加强对林业碳汇的系统研究,明确和量化我国干旱区人工林造林再造林对全球气候变暖所作出的贡献。研究可为干旱区林业碳汇项目开发和管理提供方法上的参考依据。It is a widely recognized one of the most cost-effective way to increase forest carbon sinks to control the rising of CO2 concentration in atmosphere through afforestation and reforestation. Carbon sinks of artificial plantations are also recognized as a probable and likely way to mitigate global climate change. According to the national and international calculation rules of tree-planting CO2 emission reduction,this study proposed a method to calculate the effect of the large-scale tree-planting CO2 emission reduction through afforestation and reforestation based on the characteristics of the natural environment in arid areas. This paper discussed the ways how the calculation factors of the emission reduction were selected and suggested that a comprehensive research system should be put in place to reinforce the researches on forest carbon sinks from the perspectives of policy,technology and marketing,which could clearly and quantitively measure our country＇s contribution to mitigate global climate changes through afforestation and reforestation in the arid areas. The results of the study provided useful support to the development and the management of afforestation carbon sequestration projects in arid areas.
