摘要
[目的]为准确估算区域森林碳储量,研究分析浙江天童主要树种含碳率。[方法]应用干烧法对天童地区主要针叶、阔叶乔灌木树种和毛竹不同器官的含碳率进行测定。[结果]不同树种器官含碳率范围在36%~51%,针叶树种器官平均含碳率最高,均在48%以上,常绿灌木或小乔木的器官含碳率相对较低,50个乔灌木树种器官平均含碳率的大小顺序为干、枝、叶、根。[结论]结合实测的标准木器官生物量数据,各树种含碳率加权平均值为47%,适用于天童乃至宁波地区森林碳储量估算。
[Objective]Carbon content rate of main tree species in Tiantong,Zhejiang Province was studied. [Method]The aim was to accurate estimation of regional forest carbon stocks,the different organs carbon content rate of main coniferous and broadleaf trees and shrubs and bamboo were measured by combustion method in Tiantong region. [Result]The results showed that different species organs carbon content rates ranged between 36%- 51%,and average organs carbon content rate was highest in coniferous trees which was more than 48%,and it＇s relatively low in evergreen shrubs or small trees organs. The order of average carbon content rate was stem branch leaf root for 50 woody plant species organs. [Conclusion]Combined with the measured biomass data of standard stems,the weighted carbon content rate is47%,which is suitable for the estimation of forest carbon stocks in Tiantong and Ningbo area.
