| 摘 要： | 采用定位研究方法, 从生态系统服务功能角度, 对比研究了中亚热带区域7种典型森林生态系统碳、氮储存功能。结果表明, 次生常绿阔叶林碳、氮储存功能最强, 杉阔混交林碳、氮储存功能比同林龄的杉木纯林强, 而第1代杉木纯林碳、氮储存功能强于连栽杉木纯林。生态系统碳、氮储存功能空间分布基本一致, 土壤层是主要部分, 其次为乔木层, 然后是根系, 林下植被层和凋落层所占比例最小。相关分析表明, 土壤碳、氮储存功能与林下植被生物量、森林凋落物现存量之间都具有良好的线性关系, 但与地下部分生物量相关性不明显。 |

| Abstract: | A comparative study on carbon (C) and nitrogen (N) storages under different typical forest ecosystems in mid-subtropical regions was conducted in 2006 via a localized method.The results show that C and N storages are highest under natural secondary evergreen broad-leaved forests.C and N storages in mixed broad-leaved and Chinese-fir forests are greater than in pure Chinese-fir forests.First rotation of pure Chinese-fir stands has higher C and N storages compared with successive pure Chinese-fir stands.Spati... |
