通过野外调查,选取黄刺玫群落122个样方的20种优势物种,运用多物种方差比值（VR）,χ2检验,OI指数,AC值以及Pearson相关系数和Spearman秩相关系数对其进行了种间关联分析.结果表明：该群落内物种整体关联性表现为负关联不显著;负关联的种对数远大于正关联的种对数,呈显著关联和极显著关联的种对数所占比例较小.这说明黄刺玫群落不稳定,群落内存在激烈的竞争,群落处于演替的初期.20个物种种对关系表现出了不同的性质,这可能是群落内环境异质性所致.种间关联的研究可以反映出由物种生态特征所形成的有机联系,研究结果对黄刺玫群落的保护与利用有一定的指导意义.

Through field investigation,20 dominant species were selected from 122 plots of Rosa xanthina community to analyze their interspecific associations by using multi-species relevance（variance ratio,VR）,χ2-test,Ochiai index,AC value,Pearsons′ correlation coefficient,and Spearman′s rank correlation coefficient.First,the results indicated that the overall correlation of all species was negative,but not significant.Second,the pairs having negative correlation we are much larger than the positive correlation of all the species pairs and the proportion of species-pairs was small which has a significant or highly significant correlation.It demonstrated that the community was unstable for the fierce competiton among species,and the community was in the early stages of succession.The species-pair associations among the 20 common species had different properties,which might be caused by the heterogeneity of the environment within the community.The study of interspecific association could reflect the organic link formed by the ecological characteristics of plant species,and the results would have certain practical significance for the protection and restoration of Rosa xanthina community.
