摘　　要：1 引言 研究林下乔木幼苗的分布格局及其与环境因子的相互关系,不仅可以表达植物种群中幼苗群的特征。In this paper, different methods are used to study the distribution pattern of saplings of Neolitesea aurata var. glauca, Castanopsis carlesii var. spinulosa and Symplocos lancifolia under evergreen broad-leaved and coniferous forest. The strength and area of their concentrated distribution are identified, and the relationship between distribution pattern and environmental factors are discussed. At the same time, the advantages and disadvantages of two methods (square grid method and transect plot method) used for studying the distribution pattern of plant population are analyzed.
