Carbon storage and spatial distribution in Phyllostachys pubescens forest in Dagangshan Mountain of Jiangxi Province
摘要
Abstract
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/hm~2, 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/(hm~2·a), of which vegetation and soil were 11.36 and 0.79 t/(hm~2·a), respectively.关键词
