摘要:

根据四个代表性样地的典型取样资料,运用数学分析方法,研究桂东北山地五列木种群的结构与分布格局及其动态。结果表明,五列木的重要值远高于群落中其它种类,优势度十分突出,为优势种群; 分布格局呈聚集分布,其成因主要是由环境因子的影响所决定的; 幼树数量大,种群的年龄结构呈发展型。关键词: 五列木种群; 优势种群; 聚集分布; 发展型

关键词: 五列木种群优势种群聚集分布发展型

Abstract:

Based on the data of representative sampling in four representative sample plots in Pentaphylax euryoides population distribution area,the structure,distribution patterns and dynamic development of P.euryoides population were studied by using mathematical analysis method. The result indicated that the importance value of P.euryoides was far higher than other species in these communities,its dominance degree was outstanding,and its distributing pattern was aggregated distribution. This was mainly decided by effect of environmental factors. The number of young trees was large,and the age structure of P.euryoides was developing.

Key words: P.euryoidespopulation preponderant population clusters distribution development model
