沙县水南国有林场森林碳储量特征

利用福建省沙县水南国有林场森林资源清查资料,依据生物量转换因子连续函数模型,探讨了沙县水南国有林场森林碳储量分布。结果表明,森林碳储量主要集中于杉木、马尾松林,因林场大力发展阔叶林,木荷与其他阔叶类林分的碳储量也相对较高。各林分的碳储量主要分布在成熟林龄级、中大径材经营方式及肥沃级与较肥沃级立地条件。

The characteristics of forest carbon storage on Shuinan National Forest Farm in Shaxian County,Fujian Province

The forest inventory data from the Shuinan National Forest Farm in Shaxian County of Fujian Province was used to estimate the forest carbon storage distribution based on the continuous function model of biomass conversion factor.The results showed that the forest carbon storage was mainly concentrated in Cunninghamia lanceolata and Pinus massoniana plantations, while broadleaf trees such as Schima superba and others broadleaf trees also had comparatively high percentage of carbon storage due to the promotion of broadleaf forests.Major carbon storage of different forest types was associated with mature forest age, medium and large diameter timber management style, and fertile and comparatively fertile sites.
