摘要
黄山松在我国东南部海拔700—2000m中山带广泛分布,是该地区森林群落中重要的组成成分。黄山松种群在森林群落演替中起着先锋种群的作用。但在裸岩陡坡或峰岭梁岗等特殊生境中,黄山松种群亦能形成稳定的群落。本文在种群的水平上,分析了浙江省松阳县关山源地区黄山松种群在不同演替阶段群落中和不同生境中的年龄结构与种群空间分布格局,并探讨了它们的动态规律及其与环境之间的相互关系。黄山松种群的研究不仅有助于探讨植物生态学研究中的一些理论问题,而且对经营管理和保护利用具有一定的实践意义。
Pinus taiwanensis is a widely distributed tree species in southeastern China at an elevetion of 700—2000m, one of the important components of the forest communities in this region. Pinus taiwanensis population of ten plays a pioneer role in succession series, and in some special habitats such as rocky steep slopes or ridges, Pinus taiwanensis population can also form rather stable and persistent open pine f orest communities.This study was carried out in Guanshanyuan district of Songyang County, Zhejiang Province. On the basis of a census of all individuals of Pinus taiwanensis at various successional phases and different habitats, age structure, spatial pattern, their dynamics and relationships to environment are described. The Study on Pinus taiwanensis population can not only throws some light on some theoretical themes in plant ecology studies, but is also of practical significance for forest management, utilization and preservation.
