| 摘 要： | 为了获得广东地区毛竹(Phyllostachys pubescens)的碳含量以及准确估算广东地区毛竹的碳储量和碳汇能力,采用湿烧法对广东省龙川县、南雄市5~6 a生毛竹不同器官、不同径阶、不同竹干高度的碳含量进行分析.结果表明:毛竹的平均碳含量为509.91 g/kg,毛竹不同器官碳含量大小关系为枝(524.51 g/kg)>干(523.24 g/kg)>根(504.04 g/kg)>叶(487.85 g/kg);毛竹的竹秆和枝的碳含量差异均不显著,竹秆和枝与其它器官的碳含量差异均显著(P<0.05);毛竹竹秆不同高度位置碳含量差异不显著.以上结果说明,毛竹不同器官之间碳含量存在差异性.为了提高对某一区域毛竹碳储量估算的准确度,需对该区域毛竹各器官碳含量进行精确的地面实测.

| Abstract: | In order to obtain the carbon content values of Phyllostachys pubescens, and to accurately
estimate the carbon storage and the carbon sequestration of the ecosystem of P. pubescens in Guangdong province,
the carbon content of 4 to 6 years old P. pubescens were measured by the wet burning method in Longchuan
county and Nanxiong city. In addition, the carbon content of these P. pubescens in different organs, diameter
grades, and height of P. pubescens stem were analyzed. Experimental results showed that the average carbon
content of P. pubescens was 509.91g/kg. With respect to P. pubescens organs, the descending carbon content
rates are: branches (524.51 g/kg)>trunks (523.24 g/kg)>leaves (504.04 g/kg)>roots (487.85 g/kg). The carbon
content of P. pubescens trunks and branches had no significant difference. Compared with other organs, the carbon
content of P. pubescens trunks and branches had significant difference (P<0.05). With respect to vertical trunk
positions, the carbon content of P. pubescens had no significant difference. The above results showed that there
was a difference in carbon content between different organs of P. pubescens. In order to improve the accuracy of estimating the carbon storage of P. pubescens in a certain region, it is necessary to carry out accurate ground tests
on the carbon content of P. pubescens organs in the region. |
