摘要/Abstract

摘要： 根据西藏自治区2002—2010年退耕还林工程逐年造林的树种、面积数据,利用国家森林资源连续清查中人工林生长的历史数据拟合造林树种生长曲线,结合经文献调研所获得的树种生物量扩展系数、木材密度和碳含量等参数,采用“人工林生长曲线法”估算出西藏未来50年退耕还林工程林的碳汇潜力。结果表明:在2020,2030,2040,2050,2060年,西藏的退耕还林工程林碳汇在无采伐模式下分别为0.214,0.205,0.159,0.087,0.054 TgC/a;在采伐模式下分别为0.214,-0.205,0.171,0.243,-0.352 TgC/a。

Abstract: Based on the tree species and their areas afforested under the Grain-for-Green Program(GGP) in Tibet from 2002 to 2010,the carbon sequestration potential of stands under the GGP was estimated for fifty years in the future by making use of the growth curves for different tree species simulated from the data about plantation growth of the National Forest Inventory and the tree biomass expansion factors(BEF),wood density(WD) and carbon fraction(CF) obtained by research literatures.The results showed that the carbon sinks in the GGP stands in Tibet will reach 0.214,0.205,0.159,0.087,and 0.054 TgC/a by the year of 2020,2030,2040,2050 and 2060 in no cutting scene,but it will reach 0.214,(-0.205),0.171,0.243,and(-0.352) TgC/a in cutting scene.
