摘　　要：提高林分碳储量估测精度，对于研究区域尺度上森林固碳功能具有重要的意义。本文以上海外环林带女贞（Ligustrum lucidum）人工林为研究对象，构建了女贞立木及各器官（根、干、皮、枝、叶）生物量方程，并对9年生女贞人工林乔木层、地表枯落物层和土壤层（0～100 cm）碳储量进行了估测。结果表明，女贞立木及各器官生物量方程拟合效果较好（R2〉0.9, P＜0.01）。女贞人工林生态系统总碳储量为169.89 t·hm-2，其中林分乔木层碳储量为10.48 t·hm-2，地表枯落物层碳储量为1.54 t·hm-2，林分土壤（0～100 cm）碳储量所占比例最大，为157.7 t·hm-2。在女贞人工林乔木层生物量中，树干占林木生物量的比例最大（40%），其次分别为枝（20%）、根（15%）、叶（11%）和皮（4%）。It is essential to improve the estimation of carbon storage in stands for assessing the forest carbon sink at local and regional scales. In this study, the carbon storage of tree biomass, forest floor and soil （0-100 cm） in three Ligustrum lucidum plantations in Shanghai OutLoop Forest Belt were investigated, and allometric equations for different organs such as root, trunk, bark, branch and foliage were established. The results showed that there was a good relationship between biomass and the diameter at breast height for the allometric equations of individual trees and different organs （R2〉0.9, P〈0.01）. Total carbon storage of the L. lucidum plantation ecosystem was 169.89 t·hm-2, of which the carbon storage amounts of tree biomass, forest floor, and soil （0-100 cm） were 10.48, 1.54 and 157.7 t·hm-2, respectively. In the tree biomass carbon storage of L. lucidum stands, the trunk, branch, root, foliage and bark proportionally accounted for 40%, 20%, 15%, 11% and 4%, respectively.
