摘　　要：陆地碳汇中约有一半储存在森林生态系统中,林业碳汇理论的发展是碳汇活动和项目实施的关键。根据碳源通过碳循环最终储存在木材中这一原理,林木的储碳量可计算为:碳固定量=木材的材积×基本密度×1/2,因此,笔者提出了通过提高木材的生长量、比重和提取物等来提高碳素固定率的林木育种方法。About a half of land forestry carbon--sequestration is stored in forest ecosystem. It is the key for the carbon--sequestration activity and item actualizing to research the theoretic of forestry carbon--sequestration. For the principle of carbon storing in wood through the carbon cycle, wood carbon--sequestration can calculate with, carbon fixation= wood volume standard density 1/2, therefore, the new wood breeding method which can heighten the fixed rate by enhancing the growth quality, specific gravity and extract of wood is proposed by the authors.
