中文摘要	本文对两类处于不同演替阶段的天然次生林,从直径生长、胸高断面积生长、材积生长、林木死亡率等方面进行了对比分析.研究结果表明:随着演替的进程,天然次生林直径生长、胸高断面生长和材积生长呈现下降趋势,林木死亡率也呈现明显的下降趋势,其主要原因是,在演替的早期阶段,速生喜光先锋种在林分中占据较高比例,进而林分表现出较高的死亡率和较高的生长力,但是随着演替的进行,喜光先锋速生树种逐步被耐荫的顶级或亚顶级树种所取代,进而表现出低生长和低的死亡率.
英文摘要	Forest dynamics is an important theoretical base for making forest management plan.In order to know the forest growth dynamics to support the local forest management,two types of tropical secondary forest of different succession serial were studied in terms of diameter growth,basal area growth,stand volume growth arid stem mortality.The result showed that with the succession progress,the growth of basal area,diameter and stem volume indicated a declining pattern and so was the stem mortality.The reason for this phenomenon is that in the early succession stage,the poineer tree species contituted very high propotion,hence showed the high mortality and growth rate,but with the succession process,the poineer tree was replaced by the climax or sub-climax tree species which caused the low growth rate and mortality.Understanding the dynamics of the secondary forest is helpful to the sustainable forest management.
