摘    要: 采用2×2列联表,通过方差分析、X2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。

关 键 词:森林群落    次生演替    种间联结

Abstract:A series of techniques including the analysis of variance, X2 and Ochiai were used together with a 2 × 2 contingency table in order to analyze the interspecific associations of dominant species in several different communities in a secondary succession series in Heishiding Natural Reserve, Guangdong Province. The results indicated that the association of species showed no correlation in early successional stages, a positive correlation in mixed forest stages, negative correlation in evergreen broad-leaved forest stages dominated by heliophytes and a significant positive correlation in evergreen broad-leaved forest stages dominated by mesophytes. The interspecific associations between the main species pairs were not formed by the early successional stage but came into being in the mixed forest stage and evergreen broad-leaved forest stage dominated by heliophytes. Most associations indicated competition between species pairs and showed direct competition. Complicated interspecific associations were formed in evergreen broad-leaved forests dominated by mesophytes. In this forest there were positive interspecific associations between species pairs in the same tree layer and negative interspecific associations between species pairs in across layers.
Keywords:Forest communities  Secondary succession  Interspecific associations
