摘要:
 通过对云南省景谷县思茅松天然林的群落结构、物种组成、物种多样性等特征的分析,揭示计划烧除对云思茅松天然林的影响,以期对其可持续经营管理提供科学依据。结果表明,计划烧除显著影响到思茅松天然林各群落层次的物种组成,计划烧除后乔木层物种丰富度由42种减少为24种,灌木层物种丰富度没有显著变化,但物种组成发生显著变化,草本层物种丰富度由23种增加到35种,计划烧除后紫茎泽兰重要值降低,蕨菜重要值明显增加。计划烧除显著降低了思茅松天然林的物种丰富度,物种随面积增长受到显著影响,物种累积率下降,思茅松天然林的Shannon-Wiener指数降低,Pielou指数增加。计划烧除显著提高了小径级乔木物种多度。
Abstract:
 In order to examine the impacts of prescribed burning on Pinus kesiya var.langbianensis natural forest and natural secondary forest occurring in Jingku County of Yunnan Province,and to provide scientific supports for sustainable management of the forests,this paper analyzed the community structure,species composition and characteristics of species diversity of the forests of the results were as follows.Prescribed burning could significantly affect the species composition at all community levels of the forests.Species richness of the tree layer decreased from 42 to 24 after prescribed burning.Species richness of the shrub layer had no changes.Species richness of the herb layer increased from 23 to 35,and the important value of Eupatorium adenophorum decreased and important value of Pteridium aquilinum significantly increased after prescribed burning.Prescribed burning on P.kesiya var.langbianensis natural forest significantly decreased the species richness,and the species accumulation rate decreased with the development of species-area.The Shannon-Wiener index decreased and Pielou index increased after prescribed burning,while species abundance of small diameter trees increased significantly.
