碳中和背景下西北荒漠区林业碳汇建设及灌木林CCER开发方法学研究

Research on forestry carbon sink construction and shrub CCER development methodology in northwest desert area under carbon neutralization background

西北荒漠区是中国沙漠最为集中的地区。灌木林对防治荒漠化、协调生态平衡具有重要作用,开展灌木林碳汇造林项目已成为西北地区改善生态环境的必要手段。甘肃省灌木林面积为374.44万hm^(2),居全国第5位,目前灌木林的碳汇量计算依赖于全国平均值,不能客观反映西北地区灌木林的碳汇量。结合甘肃省实际情况,就林业碳汇建设、碳汇造林项目等重要方法进行简要分析,以期为开展西北荒漠区灌木林碳汇造林CCER开发项目做基础的指导与参考。

The desert in northwest China is the most concentrated area in China.Shrubby forest plays an important role in preventing desertification and coordinating ecological balance.It has become a necessary means to improve ecological environment in northwest China to carry out shrubby forest carbon sequestration project.The area of shrubs in Gansu province is 3.7444 million hm^(2),ranking the 5th in China.The carbon sink of shrubs in Gansu province depends on the national average,which cannot objectively reflect the carbon sink of shrubs in northwest China.Combined with the actual situation of Gansu province,this paper briefly analyzed the important methods of forest carbon sequestration construction and carbon sequestration afforestation project,in order to provide basic guidance and reference for developing CCER project of shrub carbon sequestration afforestation in northwest desert area.
