摘要
以华西雨屏区1998年退耕还林地杂交竹林为研究对象,对其碳含量、碳储量及其空间分配特征进行分析。结果表明,杂交竹各器官碳含量为0.4720～0.5133g/g,平均碳含量为0.4950g/g,以竹杆碳含量(0.5133g/g)最高,竹枝碳含量(0.4720g/g)最低,各器官碳含量表现为竹杆>竹蔸>竹叶>竹根>竹枝;不同年龄的杂交竹单株碳储量大小顺序为3年>2年>1年,同一年龄单株最大碳储量是最小碳储量的1.31～1.88倍;杂交竹林各器官总碳储量为17.223t/hm2,其各器官碳储量表现为竹杆(70.12%)>竹枝(10.99%)>竹叶(9.85%)>竹根(7.25%)>竹蔸(1.79%)。
Abstract Taking hybrid bamboo which was from converting cropland to forest in Rainy Zone of West China in 1998 as the study object, the carbon content, stock, and spatial distribution characteristics were analyzed. The results showed that carbon content in hybrid bamboo of dif- ferent organs ranged from 0.472 0 to 0.513 3 g/g, and the average carbon content was 0. 495 0 g/g. The carbon content in truck was the highest （0.513 3 g/g）, while it was the lowest （0. 472 0 g/g） in branch, and the order of carbon content in each organ was as follows： truck 〉 underground truck 〉 leaf 〉 root 〉 branch. The order of carbon stock in hybrid bamboo of different ages was 3 a 〉 2 a 〉 1 a, and the car- bon stock discrepancy of hybrid bamboo of the same age was 1.31 - 1.88 times. The total carbon storage of hybrid bamboo forest was 17. 223 t/hm2, and the spatial distribution was as trunk（70.12% ） 〉 branch （ 10.99% ） 〉 leaf （9.85%） 〉 root （7.25%） 〉 underground truck （1.79%）.
