摘要:采用收获法研究了江西大岗山毛竹林生态系统的碳贮量及其分布特征。结果表明:毛竹各器官碳密度波动在0.4630~0.4917g/g,其大小顺序为竹枝>竹秆>蔸根>竹蔸>竹叶。随着毛竹年龄的增长,碳密度无明显的变化规律。在毛竹林植被层中,碳密度依次为:竹枝>竹秆>竹鞭>蔸根>鞭根>竹蔸>竹叶>林下植被>枯落物。毛竹林生态系统土壤层碳密度以0~20cm层最高,且各层次之间碳密度差异极显著。毛竹林生态系统碳贮量为243.22t/hm2,其中土壤层碳贮量占84.03%,植被层占15.97%。毛竹林生态系统年固碳量为12.15t/(hm2.a)。其中植被层年固碳量为11.36t/(hm2.a),土壤层年固碳量为0.79t/(hm2.a)。
Carbon storage and spatial distribution in Phyllostachys pubescens forest in Dagangshan Mountain of Jiangxi Province showed that the average carbon density in all P. pubescens organs ranged from 0.463 0 to 0.491 7 g/g. The storage order from high to low was branch,stem,root,rhizome and leaf. The average carbon density of P. pubescens organs was not correlated to their ages. The order of vegetation carbon density in P. pubescens was branch,stem,sheath,root,rhizome,leaf,understory vegetation and litter. Soil carbon density was highest in the surface layer (0-20 cm ),differing significantly among different soil layers. The total carbon storage of the P. pubescens ecosystem was 243.22 t/hm2 ,where soil and vegetation accounted for 84.03% and 15.97%,respectively. Annual total carbon fixation of the P. pubescens ecosystem was 12.15 t/(hm2·a) ,of which vegetation and soil were 11.36 and 0.79 t/(hm2·a) ,respectively.
