固碳效益是侵蚀退化地水土保持效益的重要组成部分,其对全面评价生态修复意义重大。从人工促进生态修复林分固碳功能出发,以裸露地为对照,不同人工修复措施林分为研究对象,对其碳储量及固碳价值进行了研究。结果表明,人工修复显著增加了植被碳库和土壤碳库的碳储量,强烈干扰马尾松、竹节沟马尾松、种草竹节沟马尾松和竹节沟湿地松植被碳库分别为6.12,6.83,8.20和32.69t/hm2,其土壤碳库分别为裸露地的1.16,1.37,1.60和2.71倍,固碳总价值分别比裸露地增加了0.36,0.60,0.87和2.78倍。
Carbon sequestration benefits are an important part of soil and water conservation benefits of degraded soil erosion, which is of great significance for the comprehensive assessment of ecological restoration. Based on the artificial carbon sequestration function of artificial restoration of forest ecosystem, bare forest was used as the control, and different artificial restoration measures were used as research object to study its carbon storage and carbon sequestration. The results showed that the artificial restoration significantly increased the carbon storage of vegetation carbon pool and soil carbon pool, and strongly interfered with Pinus massoniana, Pinus massoniana and Pinus sylvestris var.mongolica and Pinus elliottii wetland carbon pools were 6.12, 6.83, 8.20 and 32.69t / hm2, respectively. The soil carbon pools were barely 1.16, 1.37, 1.60 and 2.71 times of the bare soil, respectively. The total carbon sequestration value increased by 0.36, 0.60, 0.87 and 2.78 times respectively.
