摘要
本文采用样条法及多种格局分析方法对贵州盘县特区矮杨梅种群及其大、小灌木群的分布格局进行了研究。结果表明，盘县特区矮杨梅种群个体数量分布格局主要由大灌木群格局决定，它与大灌木群均呈随机分布格局；而小灌木群则趋于集中分布，但分布强度较弱，并且集中分布面积较小。同时。
Different methods of pattern analysis are used to study the distribution pattern of Myrica nana Cheval population、its big shrub group and small shrub group by a grid of quadrats The patterns of the populational individuals and its big shrub group are random distribution,but that of its small shrub group is near concentrated distribution And the small shrub group has slight intensity of spatial pattern and small area of concentrated distribution In addition, the advantages and disadvantages of three quadrat variance methods are analyzed and compared in this paper
