摘要:
运用方差比率法(VR)、χ2检验、Ochiai指数、联结系数AC对中国科学院沈阳树木园的27种木本植物优势种的关联性进行了分析。结果表明：园内优势种总体上表现为不显著的正关联，27种优势种组成的351对树种对中，χ2检验有18对表现出显著或极显著关联性，其中15对表现为正关联，3对表现为负关联；结合OI、AC值，得出351对种对中绝大部分呈不显著关联，极小部分表现出显著或极显著关联，说明优势种种群间关系松散，趋于独立，树木园这个近自然林群落具有明显的次生性和年轻性；综合种间联结关系和树种的生态习性，得出13个表现良好的生态组合，为城市人工林的营建以及退化植被的恢复提供了一定的参考。
Abstract:
Variance ratio(VR)，χ2 test，Ochiai’s coefficient(OI) and association coefficient(AC)were used to study the association of 27 dominant species in Shenyang Arboretum，Chinese Academy of Sciences.The results showed that the overall association among dominant species were not significantly positive correlation27 dominant species composed 351 species pairs.According to the result of χ2 test，the interspecific associations of 18 species pairs were significant or extremely significant，15 speciespairs revealed significant or extremely significant positive correlation，3 species pairs revealed significant or extremely significant negative correlation.Combined with Ochiai’s coefficient(OI) and association coefficient(AC)，it concluded that the majority of the 351 species pairs showed no significant association，a very small part of species pairs showed significant or extremely significant correlation.It indicated that the dominant species were not closely related to each other and they were relatively independent distribution，which showed the obvious secondary and juvenility characteristics.According to the interspecific association and the ecological habits of dominant species，13 ecological species groups were obtained.These ecological species groups would provide a certain reference on the construction of urban forest and the restoration of degraded vegetation.
