不同坡位樟生物量及其分配率研究

Study on Biomass and Distribution Rate of Cinnamomum glanduliferum(Wall.)Nees in Different Slopes

摘要:

摘要：通过对将乐县6a生樟人工林地上部分和地下部分生物量及其分配进行了调查。研究结果表明：从人工林生长指标来看，不同坡位樟平均胸径生长量和平均树高生长量均表现为下坡位>中坡位>上坡位；从林分生物量来看，下坡位樟林分总生物量最高，中坡位次之，上坡位樟林分总生物量最低；就地上部分各器官生物量分配率而言，不同坡位樟各器官生物量分配率均表现为干>枝>叶。从平均木各径级根生物量分配率来看，樟不同坡位均表现为骨骼根＞中根＞粗根＞大根＞小根＞细根。

Abstract：The biomass of on and under ground and its distribution of 6-years-old Cinnamomum glanduliferum(Wall.)Nees were investigated in Jiangle County in Fujian Province. The result indicated that the average diameter at breast height and height of Cinnamomum glanduliferum(Wall.)Nees in different slopes as follows downslope was highest, midslope was next , upslope was last from growing indicator of plantation. The downslope was the highest amount of biomass, midslope was next , upslope was last from biomass of stand, biomass and distribution rate of organs in different slopes that trunk was highest, branch was next, and leaf was last from biomass distribution rate over ground.. stump root > middle root ＞large root ＞coarse root＞big root ＞ rootlet ＞ fine root from biomass and distribution rate of diameter class of average tree.
