In order to accurately estimate the carbon storage of Quercus aliena var.acuteserrata stand-types in Xiaolong Mountains,Gansu Province,mensuration and research on forest biomass of the stand-types were carried out.Based on the data from 513 sample plots and 178 sample stems,regression equations of each organs of Q.aliena var.acuteserrata were simulated.Then the tissues' carbon content rates were measured on each organs of 14 shrub species,10 herbaceous plants and the forest litters under Q.aliena var.acuteserrata tree species by dry combustion method.Based on the biomass data of stand sample plots,the mean carbon content rates of the tree layer of Q.aliena var.acuteserrata stand-types had been calculated.In the end,the carbon storage of Q.aliena var.acuteserrata forests was estimated.The results showed that: 1) the average forest biomass of Q.aliena var.acuteserrata forests in Xiaolong Mountains was 84.047 2 t/hm~2.2) the mean tissues' carbon content rate of Q.aliena var.acuteserrata species was 0.465 3,and that of tree stratum was 0.467 6.3) the carbon storage of Q.aliena var.acuteserrata stand-types in Xiaolong Mountains was 39.222 5 t/hm~2.
