赤水河清香木群落主要树种种间关系与生态种组

摘要

In order to clarify inter-species relationship and ecological species groups of Pistacia weinmannifolia community in Chishui river basin, variance ratio ( VR) of the overall association, based on the data of general community survey, Pearson product-moment correlation, Spearman rank correlation were used in quantitative anal-ysis.The results were as follows, (1) The Pistacia weinmannifolia community was in the early stage of vegetation succession.(2) The overall association of species in the community was significant positive.The result of inter-species co-variation was also the same. (3) Through constellation diagram, these species could be divided into three ecological groups, namely Mutual, Marginal and Characteristic species group.%为探明清香木群落中物种种间关系及生态种组构成，在对其进行群落生态学样方调查的基础上，使用方差比率（ VR）法进行多物种间关联性测定与检验，运用积矩相关（ Pearson）与秩相关（ Spearman）对物种多度数据进行相关性分析。结果显示，（1）清香木群落处于植被演替早期阶段；（2）清香木与群落内多数物种形成显著正联结，种间协变测定的结果分析与此相符；（3）星座图呈现3个组团，据此将清香木群落中的优势种划分成3个生态种组并命名为共有种组（ Mutual species group）、边缘种组（ Marginal species group）和特征种组（ Characteristic species group）。
