固碳效益是退化土地水土保持效益的重要组成部分，在生态修复综合评价中具有重要意义。以裸地为对照，对不同类型的人工植被进行了研究。对其碳库和固碳值的研究表明，人工恢复后的植被碳库和土壤碳库均有明显增加。强干扰马尾松、毛竹沟马尾松、玻璃竹沟马尾松、毛竹沟马尾松的植被碳库分别为6.12、6.83、8.20、32.69t/hm2，土壤碳库分别是裸地的1.16、1.37、1.60、2.71倍，固碳总量分别是裸地的0.36、0.60、0.87、2.78倍。
Carbon fixation benefit is an important part of the soil and water conservation benefits on degraded land and has a great significance in comprehensive evaluation of ecological rehabilitation. Taking bare land as a contrast,different types of human induced vegetation are studied. According to the studies on carbon pool and carbon fixation value of them,there was an obvious increase in vegetation carbon pool and soil pool after human induced rehabilitation. Vegetation carbon pools in strong interfered Pinus massoniana,bamboo-burl-groove Pinus massoniana,glassed-bamboo-burl-groove Pinus massoniana,and bamboo-burl-groove Pinus elliotti were 6.12,6.83,8.20,and 32.69 t/hm2; soil carbon pools of them were 1.16,1.37,1.60,and 2.71 times those on bare land; and the total values of carbon fixation were 0.36,0.60,0.87,and 2.78 times those on bare land,respectively.
