| 摘 要： | 对鼎湖山季风常绿阔叶林1 hm2永久性样地内粗死木质残体(Coarse woody debris,简称CWD)的生物量、存在形式及分解状态进行研究.结果表明:1)鼎湖山季风常绿阔叶林CWD的生物量为42.09 t hm-2,其中倒木和枯立木分别为32.81 t hm-2、9.28 t hm-2,所占比例分别为77.9%、22.1%.1999~2010年间CWD年均输入量为1.68 t hm-2a-1.2)CWD主要优势树种为锥栗(Castanopsis chinensis)、黄杞(Engelhardtia roxburghiana)和荷木(Schima superba),所占比例分别为54.0%、15.1%和13.9%.3)CWD径级主要分布在30 cm以下,但对CWD生物量贡献最大的径级在30 cm以上.4)CWD的分解状态主要为中度分解状态,占CWD总生物量的61.2%.研究还表明,鼎湖山季风常绿阔叶林的CWD生物量呈逐年增加趋势.图2表3参17

| Abstract: | The biomass,types and decay classes of coarse woody debris(CWD) were analyzed in a monsoon evergreen broad-leaved forest(MEBF) in the Dinghushan Nature Reserve,Southeastern China based on long-term data from a 1 hm2 permanent sample plot.The results showed that: 1) The total CWD biomass was 42.09 t hm-2,of which the fallen trees and standing dead trees were 32.81 t hm-2 and 9.28 t hm-2,respectively.Fallen trees were the main type and accounted for 77.9% of the total CWD biomass,while the percentage of stand... |
