以68个灌木样方的重要值矩阵和2×2列联表为基础,结合实地调查,应用方差比率法、χ2检验、Pearson相关系数及Spearman秩相关系数法,对云丘山地区灌木群落的20个优势种、190个种对的关联性进行了定量研究。方差比率法结果表明,20个优势种总体间关联为显著正相关,云丘山地区的灌木群落处于较稳定的状态；χ2检验、Pearson相关系数、Spearman秩相个关系数结果表明,大部分种对的种间关联未达到显著程度,种间联结较为松散,群落结构及其种类组成将逐渐趋于完善和稳定；根据这20个优势种对环境的适应方式和主导生态因素辅助以PCA排序,可将它们划分为两种生态种组。以上结果揭示了该地区主要优势物种与环境的相互关系。

With important value matrix and 2×2 list of 69 shrub samples as the foundation,with variance ratio meth-od,x2-test,Pearson correlation coefficient and Spearman rank correlation coefficient and real station,the relevance of 20 dominant species and 190 species pairs were studied in Yunqiu Mountain area.The results of variance ratio showed that 20 dominant species overall displayed significant positive correlation.The community structure and species com-position would gradually tend to perfect and stable.The x2-test,Pearson correlation coefficient and Spearman rank correlation coefficient showed that most of the species pairs association did not reach significant level,species correla-tion were relatively loose.And it showed that the shrub community was the stabile in Yunqiu mountain area.Accord-ing to the adaptation way of 20 dominant population to the environment and leading ecological factors aided by PCA sorting,they were divided into two ecological species group,which revealed the dominant species of the region’s ma-j or relationship with the environment.
