内蒙古森林碳储量及其区域变化特征

根据内蒙古第6次森林资源连续清查资料,分析计算了内蒙古及各区域森林碳储量的变化。结果表明：内蒙古森林总碳储量为92 016.13万t,占同期国家森林资源总碳储量的12.01%,其中林木总碳储量为73 028.68万t,根系总碳储量为18 987.46万t。内蒙古各流域森林总碳储量为90 734.74万t,五大沙地森林总碳储量为4 615.91万t,天然林保护工程区森林总碳储量为65 080.17万t,风沙源治理工程区森林总碳储量为6 122.19万t,退耕还林工程区森林总碳储量为29 779.21万t,三北防护林工程区森林总碳储量为33 510.91万t。不同地区间森林碳储量差异的总体趋势是＂西低东高＂。

Forest Carbon Storage and Its Regional Change Feature in Inner Mongolia

On the basis of the sixth continuous forest inventory report of Inner Mongolia,the change of forest carbon storage and its regional change have been analyzed and calcaulated.The results show that the total forest carbon storage is 920.1613 million tons,taking up 12.01 percent of the total national forest carbon storage in the corresponding period,among them,the trees total carbon storage is 730.2868 million tons,the roots total carbon storage is 189.8746 million tons.The total forest carbon storage of all rivers in Inner Mongolia is 907.3474 million tons,the one of five sandy lands is 46.1591 million tons,the one of natural forest protection project areas is 650.8017 million tons,the one of wind and sandstorm source control project areas is 61.2219 million tons,the one of the project areas of returning farmland to forest is 297.7921 million tons,and the one of Three North shelterbelt project areas is 335.1091 million tons.The total tendency for the difference of forest carbon storage in different areas in Inner Mongolia is east high and west low.
