摘　　要：科学估算人工林碳储量是了解人工造林固碳功能的基础。我国人工林龄组成以幼龄林、中龄林为主,其中胸径小于5 cm的幼树占一定的比例。林业上对胸径小于5 cm的乔木不计算其蓄积量,因此在应用生物量—蓄积转换模型估算人工林碳储量时会导致估计值小于真实值。以西藏自治区人工林为例,通过建立单位面积蓄积—林龄的相关关系,提出了解决胸径不足5 cm的乔木碳储量估算的方法,进而估算了人工林植被碳储量。Scientific estimation of plantation carbon stocks is the basis of understanding carbon sequestration function of afforestation. The most of plantation in China were young and middle-aged forest, there were a certain proportion of those saplings with the diameter at breast height of 5 minus cm in the total afforestation. Cerrently we dont calculated accumulation on those trees with DBH less than 5cm in forestry, thus it will cause the esti- mated value less than the true value in the application of biomass-aecumulation convert models to estimate the plantation carbon stocks. Plantation of the tibet autonomous region, for example, through establishment of the relationship between unit stock volume and forest age, trees with DBH less than 5cm carbon stock estimation method was put forward, so as to estimate the plantation vegetation carbon stocks,.
