| 摘 要： | 通过在湖北全省内的12种森林类型中设置212块样地，采用标准木全株收获法测定林下灌木层生物量和碳密度，评估不同森林类型和不同地区间林下灌木层生物量和碳密度现状。结果表明，湖北省不同森林类型灌木层碳密度介于0.44~8.35 t·hm-2之间，平均碳密度为2.80 t·hm-2，最大的为天然阔叶中龄林，最小的为人工针阔混交林。从森林起源上比较，天然林灌木层生物量和碳密度明显高于人工林；从森林类型上比较，阔叶林＞针叶林＞针阔混交林；而从龄组上比较，灌木层碳密度随着林龄的增加而不断增加。不同地区间天然林灌木层碳密度除神农架林区与其他地区间均存在显著差异外，其他地区间无差异。因此灌木层生物量和碳密度只与森林起源、森林类型和林龄具有密切联系，与地区间的分布相关性不大。

| Abstract: | To understand the current situations of the shrub layer biomass and carbon density in different forest types and different regions within Hubei Province, 212 plots representing 12 forest types were established by using standard wood plants harvest method. The results showed that the shrub layer carbon density of different forest types in the ranged from 0.44 t·hm-2 to 8.35 t·hm-2, with an average value of 2.80 t·hm-2, highest in natural middle-aged broad-leaved forest, and lowest in the artificial coniferous and broad-leaved mixed forests. From the view of the origin of forests, the shrub layer biomass and carbon density of natural forest was significantly higher than those of the artificial standsplantation; from the forest types, broad-leaved forest＞coniferous forest＞coniferous and broad-leaved mixed forest; from the forest age, the shrub layer carbon density increased with the increase of forest age; from different regions, there were significant differences between Shennongjia forests and other regions, but no differences between the other regions. So the shrub layer biomass and carbon density only has a close relationship with the origin, types and ages, with little correlation with regions. |
