摘要:
森林优势树种对群落环境和结构形成具有重要的作用。文章分析了浙江省景宁县荒田湖林场针阔混交林3个50m×50m样地中黄山松Pinustaiwanensis和木荷Schimasuperba种群的径级结构与空间分布格局。结果表明，黄山松种群在3个样地中的径级结构均呈正态分布，而木荷种群的小径级个体相对较多；黄山松和木荷幼树以及大树在空间分布上具有隔离现象，木荷种群幼树阶段在小尺度上均为聚集性分布，在较大尺度上呈现随机分布的格局，而黄山松的幼树和大树的空间分布格局在不同样地间存在差异。本研究结果表明两个树种在生活史不同阶段的生态需求存在差异，进而引起空间分布格局的差异，在制定森林经营措施时应考虑优势种的径级结构及其空间分布情况。
Abstract:
Dominant trees play an important role in the formation of community environment and structure. Size-class structure and spatial distribution patterns of P.taiwanensis and S.superbapopulationin three 50 m×50 msample plots within theropencedrymion of Huangtian lake forest farm,Jingningcounty,were analyzed in this paper. The results indicated that the size-class of P.taiwanensis was normal distributed,however, there were more footpath individuals in the population. Smaller and bigger trees of the two species were spatially isolated, the sapling stage of the population of S.superba showed aggregation distribution at small scales and random distribution pattern at large scales, while the spatial distribution pattern of the sapling and mature tree of the population ofP. taiwanensisvaried from place to place.Our study showed that there were differences in the ecological needs of two species at different stages of life history, which leads to differences in spatial distribution pattern. Therefore, the size-class structure and spatial distribution of dominant species should be considered when formulating forest management measures.
