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.
The use of native tree species to transform large-scale artificial pure forests has become an effective model for the near-natural management of island plantations in our country.Using the method of relative growth equation of biomass and sample survey data, The results showed that the average carbon storage of arborous layer in Pinus thunbergii and Robinia pseudoacacia plantations were 56.81 and 37.26 t · hm -2, respectively, which were higher than the average of arbor forests in Shandong province Carbon storage (27.62 t · hm -2) .Aspect orientation is an important environmental factor affecting the island’s carbon storage, stand density is an important biological factor that affects the carbon storage of the island tree layer.The biomass of arbor layer in the Pinus thunbergii plantation There was no obvious correlation between the average accumulative rate and the tree age.The black pine with good carbon sequestration was the ideal tree species of Nanchangshan Island.
