摘要: 以浙江省天台山七子花群落为研究对象,对该群落优势种群的结构和分布格局进行了分析,结果是:组成该群落多数优势种群的龄级不完整,年龄结构为衰退型,七子花林是一个不稳定的群落;各优势种群在各样地中的分布格局均呈集群分布。用方差比率(VR)和通过2×2联列表进行X2检验的方法,检验了七子花群落乔木层18个主要树种、灌木层20个主要种类的总体相关性和各种对间的联结性。结果是乔木层主要树种间在总体上呈不显著的正相关,正联结的种对多于负联结的种对;灌木层主要种类间在总体上呈显著的正相关,正联结的种对明显多于负联结的种对。

Abstract: The author analyzed dominant population structure and distribution pattern of the Heptacodium miconioides community in the Tiantai Mountain of Zhejiang Povince. The results showed that the age-class in majority dominant populations of the community was incomplete and the age structure was declining, and that the Heptacodium miconioides forest was an unstable community; that the distribution patterns of dominant populations in various plots were of clump distribution. Using veriance ratio(VR) and x2 text by 2×2 contingency table, the paper analysed the overall relatedness between 18 major tree varieties of the tree-layer and 20 major varieties of the shrub-layer, and the interspecific association. It hence came to the following conclusion:In the tree-layer, there was unremarkable positive relatedness on the whole, and there were more species pairs of positive association than those of negative association; There was remarkable positive relatedness among the major tree varieties of the shrub-layer, and there were obviously more species pairs of positive association than those of negative association.
