摘　　要：利用乡土树种改造大面积人工纯林已成为我国海岛人工林近自然化经营的有效模式.采用生物量相对生长方程和样地调查数据相结合的方法,对山东省长岛县南长山岛人工林的优势树种黑松和刺槐的碳储量进行估算.结果表明:黑松和刺槐人工林乔木层平均碳储量分别为56.81和37.26 t·hm^(-2),均高于山东省乔木林的平均碳储量(27.62 t·hm^(-2)).坡向是影响海岛乔木碳储量的重要环境因子,林分密度是影响海岛乔木层碳储量的重要生物因子.黑松人工林乔木层生物量平均累积速率与树龄没有明显的相关性.具有良好固碳功能的黑松是南长山岛的理想树种.Using indigenous tree species to transform large area pure plantations has been an effec- tive close-to-nature forest management mode in China islands. By using the biomass allometric equation and combined with the investigation data from sampling plots, the carbon storage of the dominant species Pinus thunbergii and Robinia pseudoacacia in the plantations on the Nanchangshan Island of Miaodao Archipelago in Changdao County of Shandong Province was estimated. The aver- age carbon storage in the arbor layer of P. thunbergii and R. pseudoacacia plantations was 56.81 and 37.26 t · hm^-2, respectively, being higher than the average carbon stock （27.62 t · hm^-2 ） of tree plantations in Shandong Province. Slope aspect and stand density were the important environ- mental and biological factors affecting the tree＇ s carbon stock in the Island, respectively. There was no significant correlation between the average cumulative rate of biomass in the arbor layer of P. thunbergi plantation and the stand age. The P. thunbergii with good carbon sequestration function could be an ideal tree species on Nanchangshan Island.
