摘要/Abstract

摘要： 为了更好地了解常绿阔叶林恢复演替过程中木质残体(WD)碳储量的变化特征,对鹰嘴界马尾松林、针阔混交林、常绿阔叶林进行了调查取样,结果表明:鹰嘴界常绿阔叶林演替阶段各林分中木质残体的现存量较低,在1.26～8.82 Mg/hm²之间,大小顺序为马尾松林<针阔混交林<常绿阔叶林,随演替进程呈逐渐增加趋势;演替阶段粗木质残体(CWD)碳含量因树种及其分解等级而异,随着CWD分解等级的提高,其碳含量逐渐降低;马尾松林、针阔混交林和常绿阔叶林的木质残体碳密度分别为0.62,1.75,3.78 Mg/hm²,分别相当于各林分乔木层碳密度的0.73%、1.83%和2.92%。

关键词: 木质残体, 碳储量, 常绿阔叶林, 中亚热带, 演替阶段

Abstract: To better understand the effect of forest succession on carbon storage of woody debris(WD),carbon stock and allocation of evergreen broadleaf forest,a major zonal forest in subtropical China was investigated.Three forest types were sampled,i.e.,pine(Pinus massoniana)forest(PF),pine and broadleaf mixed forest(MF)and evergreen broadleaf forest(BF).The amount of woody debris(WD)biomass was between 1.26-8.82 Mg/hm²,in the following order:PF<MF<BF,which showed a trend of increase gradually with the succession.Coarse woody debris(CWD)carbon content varies with tree species and its decomposition level,with the improvement of CWD decomposition level,its carbon content gradually decreases.The woody debris carbon storages of PF,MF,and BF were 0.62 Mg/hm²,1.75 Mg/hm² and 3.78 Mg/hm²,respectively,corresponding to 0.73%,1.83% and 2.92% of the tree carbon storage.

Key words: woody debris, carbon storage, evergreen broad-leaf forests, mid-subtropical region, succession
