In order to understand the carbon sequestration of ecological forests in Loess Plateau, a comparative study was made on the organic carbon density (OCD) of soil, litter, and plant organs in an 8-year-old Robinia pseudoacacia plantation and nearby barren land. Comparing with the barren land, the young R. pseudoacacia plantation had a decrease (0.26 kg x m(-2)) of soil OCD, but the OCD in its litter, root system, and aboveground organs increased by 121.1%, 202.0%, and 656. 7%, respectively, with a total carbon sequestration increased by 3.3% annually, which illustrated that R. pseudoacacia afforestation on Loess Plateau had an obvious positive effect on carbon sequestration.
为了解黄土高原生态林的碳固存情况，对8年生刺槐人工林及其附近荒地土壤、凋落物和植物器官的有机碳密度（OCD）进行了对比研究。与荒地相比，刺槐幼林土壤OCD降低了0.26 kg·m-2，但其凋落物、根系和地上器官的OCD分别增加了121.1%、202.0%和656.7%，总碳固存每年增加3.3%，这表明黄土高原刺槐造林对碳固存具有明显的积极作用。
