| 摘 要：本文根据不同径级植物生物量和相应的碳含量，计算得到鼎湖山沟谷常绿阔叶林、低地常绿阔叶林和山地常绿阔叶林植被的碳密度。结果表明沟谷常绿阔叶林植被碳密度最大(125.23 t·hm-2)，其次是低地常绿阔叶林(117.50 t·hm-2)，山地常绿阔叶林最小(48.56 t·hm-2)。在植被总碳密度中，乔木层拥有绝大部分(98.4%~99.5％)，灌木层(0.2%~0.9％)、草本层(0.1~0.5％)和层间植物(0.1~0.3％)极小。在乔木层（47.78~124.63 t·hm-2）中，以树干碳密度占的比例最大(52.6~62.1％)，其次是枝桠(10.5~26.7％)和根(18.2~23.2％)，叶最小(2.3~4.2%)。垂直分配表明地上部分量碳密度大致随高度级的增加而增加。沟谷常绿阔叶林不同树种对碳贮量的贡献排序为凸脉榕(Ficus nervosa)＞假苹婆(Sterculia lanceolata)＞翅子树（Pterospermum lanceaefolium）＞鱼尾葵(Caryota ochlandra) ＞厚壳桂（Cryptocarya chinensis）＞水石梓(Sarcosperma laurinum)＞ 龙眼(Dimocarpus longan) ＞ 白颜树(Gironniera subaequalis)；低地常绿阔叶林中为锥栗(Castanopsis chinensis) ＞黄果厚壳桂(Cryptocarya concinna) ＞荷木(Schima superba)＞观光木（Tsoongiodendron odorum）＞肖蒲桃（Acmena acuminatissima）＞云南银柴(Aporosa yunnanensis)＞厚壳桂（Cryptocarya chinensis）＞黄杞（Engelhardtia roxburghiana），山地常绿阔叶林为白皮黄杞(Engelhardtia fenzelii)＞硬斗柯(Lithocarpus hancei)＞短序楠(Machilus breviflora)＞密花树(Rapanea neriifolia) ＞ 毛棉杜鹃(Rhododendron moulmainense)＞桃叶石楠(Photinia prunifolia)>藜蒴（Castanopsis fissa）。 |

| 摘 要(英文)：Carbon storage was calculated by the biomass of each height class times the average carbon content of dominate species within the same height class， and then carbon density was obtained from it divided by projected area. The whole carbon density was 125.18， 117.49 and 48.52 t·hm-2 for the ravine evergreen broad-leaved forest(REBF)， the lowland evergreen broad-leaved forest(LEBF) and the mountain evergreen broad-leaved forest(MEBF)， respectively. Of whole carbon density， 98.4%~99.5% was in tree layer， 0.2%~0.9% in shrub layer， 0.1~0.5% in herb layer， and 0.1~0.3% in interstratum plants. The carbon density in tree layer ranged from 47.78 to 124.63 t·hm-2， with the proportion of 52.6~62.1% for trunks， 10.5~26.7% for branches， 18.2~23.3% for roots， and 2.3~4.2% for leaves. Among the 3 forests，the carbon density generally increased with the tree height class. Among major species，the carbon density was of the orders： Ficus nervosa > Sterculia lanceolata > Pterospermum lanceaefolium > Caryota ochlandra > Cryptocarya chinensis > Sarcosperma laurinum > Dimocarpus longan > Gironniera subaequalis in the REBF，while Castanopsis chinensis > Cryptocarya concinna) > Schima superba > Tsoongiodendron odorum > Acmena acuminatissima > Aporosa yunnanensis > Cryptocarya chinensis > Engelhardtia roxburghiana in the LEBF，and Engelhardtia fenzelii > Lithocarpus hancei > Machilus breviflora > Rapanea neliifolia > Rhododendron moulmainense > Photinia prunifolia in the MEBF. |
