摘 要 ：在对 1 hm2永久样地调查的基础上结合优势树种 C含量的实测值 ,对鼎湖山南亚热带季风常绿阔叶林的 C贮量及其空间和种群分布特点进行了分析 ,结果表明 :( 1 )鼎湖山季风常绿阔叶林现存 C贮量为89.75 t·hm- 2 ,其中 ,干、枝、叶、根分别占总量的 5 3.0 9%、2 5 .36%、2 .64%和 1 8.31 % ;( 2 )数量上小径级个体占有绝对优势 ,1 hm2 样地内 DBH<2 0 cm的个体占总数的 95 % ,个体数量随径级的增加而迅速减少 ,而 C贮量的径级分布则大致呈“M”形 ;( 3)根据树木高度分为 4个层次 ,即 层 ( h≥ 2 0 m) , Ⅱ层 ( 1 0 荷木Schima superba>黄果厚壳桂Cryptocarya concinna>厚壳桂Cryptocarya chinensis>肖蒲桃Acmena acuminatissima>黄杞Engelhardtia roxburghiana>白颜树Gironniera subaequalis>臀形果Pygeum topengii>橄榄Canarium album>窄叶半枫荷Pterospermum lanceaefolium>华润楠Machilus chinensis>鸭脚木Schefflera octophylla>韶子Nephelium chryseum。成熟度较高的种群C贮量较高，起主导作用。

Abstract:It is of theoretical importance to understand forest standing carbon storage. Although there have been many reports on it for major forest types, most of them refer to forests in tropics, medi- and high-latitude areas in the Northern Hemisphere, few focus on forests near the tropic of cancer. The regional vegetation in Dinghushan Nature Reserve (DNR) is monsoon evergreen broad-leaved forest (MEBF). Although located in the tropic of cancer, the area is covered with different forest types, including integrate...
