摘要
根据内蒙古第6次森林资源连续清查资料,并结合森林固碳研究的相关成果,分析了内蒙古沙区森林资源的特点,并计算了碳储量的变化。结果表明,内蒙古沙区林地总面积1 097.06万hm2,森林总面积为323.82万hm2;沙区林木总蓄积量为3 633.15万m3,占内蒙古林木总蓄积量的2.67%;沙区林木总固碳储量为1 574.26万t,其中,乔木林总固碳储量为1 044.72万t,灌木林总固碳为205.35万t,根系(乔灌木)总固碳325.91万t。各沙地林木总固碳储量占沙区林木总固碳储量的96.19%,沙漠林木总固碳储量占沙区林木总固碳储量的3.81%。
On the basis of the sixth continuous forest inventory in Inner Mongolia and the relevant research achievements on carbon fixation by forest in China,the features of forest resources in sandy area in Inner Mongolia have been analyzed,and the change of tree carbon stocks has been calculated.Results show that the total area of forest land is 10.9706 million hm2 in sandy area in Inner Mongolia,and the total area of trees is 3.2382 million hm2.The total stand volume of forest in sandy area is 36.3315 million m3,taking up 2.67 percent of the total volume of forest trees in Inner Mongolia.The total carbon stocks of forest in sandy area in Inner Mongolia is 15.7426 million tons,among them,the total carbon stocks of trees is 10.4472 million tons,that of shrubs is 2.0535 million tons,and that of roots of tree and shrub is 3.2591 million tons,respectively.In Inner Mongolia,the total tree carbon stocks in sandy lands take up 96.19 percent of the total tree carbon stocks in sandy areas,and the total tree carbon stocks in deserts take up 3.81 percent of the total carbon stocks in sandy areas.
