采用标准地调查和生物量实测方法,研究了湖南省桃江县毛竹林生态系统生物量、碳含量、碳储量及空间分布格局。结果表明,不同年龄毛竹林生态系统总生物量分别为:28.147、30.889 t/hm~2和57.763 t/hm~2,其中竹林层生物量为20.254、25.036、55.685 t/hm~2,各器官生物量均以竹竿最高,占器官生物量的63.0%以上。不同年龄毛竹各器官碳平均含量为0.466—0.483 g C/g;灌木层碳含量为0.474—0.489 g C/g;草本层为0.472—0.490 g C/g;死地被物层为0.213—0.276 g C/g;土壤层有机碳含量为14.790—34.503 g C/g。各年龄毛竹林生态系统总碳储量分别为131.273、139.089 t/hm~2和167.817 t/hm~2,其中植被层碳储量为13.627—28.419 t/hm~2,占系统总碳储量的9.935%—16.935%;死地被物为0.307—0.420 t/hm~2,占0.234%—0.265%;土壤层为117.339—138.978 t/hm~2,占82.815%—89.799%。毛竹林生态系统碳储量分布格...
【英文摘要】
In this study,the biomass and carbon concentrations were measured and the carbon storages were estimated in various plant organs and components of different aged stands of Moso bamboo plantations in Taojiang county,Hunan province. The objective of the research project was to quantify the special distribution of biomass and carbon storage in bamboo forest ecosystems in order to better understanding of the dynamic property of biomass production and carbon cycle in the plantation ecosystems. The results showed...
