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.
