Abstract: In order to estimate for Robinia pseudoacacia forest carbon sink and determinate the biomass measuring parameters, based on the 60 plots of Robinia pseudoacacia forest in Taihang Mountains, the biomass exchanged coefficient (BEF) and root-shoot ratio (R) between diameter and stand age were studied. The results showed that: BEF=1.535±0.127, R=0.530±0.102, n=15, which of the young-aged Robinia pseudoacacia forest, and BEF=1.371±0.038, R=0.381±0.045, n=45, which of the middle-aged. The models of biomass and carbon sink at compartment and stand level were studied, that showed which was linear regression relation between volume and biomass, carbon sink. The model of carbon sink growth was studied, that showed the carbon sink growth of annual average was 1.79 t/hm2, which was higher.
