采用 2× 2列联表 ,通过方差分析、χ2检验、Ochiai指数对黑石顶森林次生演替过程中各阶段群落优势种的种间联结性进行了定量分析。研究结果表明 :群落的总体种间关联性在演替恢复初期表现为无相关性 ,针阔叶混交林阶段为总体的正关联 ,阳生性常绿阔叶林阶段呈总体负关联 ,中生性常绿阔叶林阶段总体呈显著正关联。在演替初期主要种对间尚未形成一定的种间关系 ,演替至混交林和阳生性常绿阔叶林阶段 ,种间关系开始形成 ,但大多表现为直接的竞争关系 ,中生性常绿阔叶林阶段形成了复杂多样的种间关系 ,表现为同层树种间的种间结合或竞争和不同层种间的结合关系
The 2 × 2 contingency table was used to analyze the interspecific associations of dominant species in different stages of secondary succession in the process of secondary succession in Heishiding Forest by analysis of variance, χ2 test and Ochiai index. The results showed that the overall interspecific association of the community showed no correlation in the initial stage of succession recovery, and the stage of coniferous and broad-leaved mixed forest was the overall positive correlation. The stage of the ecologically active evergreen broad-leaved forest was negatively correlated, The green broad-leaved forest stage showed a significant positive correlation. At the early stage of succession, some interspecific relationships have not formed between the main species pairs, and the succession is to the stage of mixed forest and the ecologically active evergreen broad-leaved forest. The interspecific relationships begin to form, but most of them show direct competitive relationship. The broad-leaved forest stage formed a complex and diverse relationship between species, showing the interspecific interspecific association or competition between species and different layers of the relationship between species
