摘要:
 为了探究北京凤凰岭岩生植物群落的物种组成和优势种群的种间关系，在样方调查的基础上，采用χ2检验、Pearson 相关系数和Spearman 秩相关系数等方法进行分析。结果表明：凤凰岭岩生植物群落有维管束植物91种，隶属于43科73属，重要值>0.010的植物有25种；χ2检验、Pearson相关系数检验和Spearman秩相关系数检验的结果较为一致，尤其是χ2检验和Spearman 秩相关系数检验，三者的正负关联比分别为0.85、0.40、0.78，极显著及显著关联种对占总种对数的比例分别为8.67%、5%、8.33%，群落整体上关联性较弱，处于相对稳定的状态；绘制χ2半矩阵图、Pearson 相关系数半矩阵图、Spearman秩相关系数半矩阵图和Spearman秩相关系数星座图；根据植物生态习性和Spearman秩相关系数的种间关系将优势种群划分为5个生态种组，结合χ2检验，可将其合并为3个生态种组；关联性较强的种对可在配置中使用，有利于形成较为稳定的人工群落，为岩生植物的园林应用和植物配置提供一定依据。
Abstract:
 In order to explore species composition of rock plant community and interspecific relationship of dominant population occurring in Beijing Phoenix Hill,a sampling survey was carried out.The data obtained were analyzed by using χ2-test,Pearson correlation coefficient,and Spearman rank correlation coefficient,as well as other methods.Totally,91 vascular species were found in the rock plant community of Beijing Phoenix Hill,belonging to 43 families and 73 genera,in which there were 25 dominant species whose important value was greater than 0.010.The results of χ2-test,Pearson correlation coefficient test and Spearman rank correlation coefficient test were relatively consistent.Positive and negative correlation ratios of the three tests were 0.85,0.40,and 0.78,respectively.The species-pairs with most significant or significant correlations accounted for 8.67%,5% and 8.33% of the total in three tests,respectively，indicating that the correlations of the community as a whole were weak,and the plant community was in a relatively stable state.Semi-matrix of χ2-test,Pearson correlation coefficient test,Spearman rank correlation coefficient and constellation diagram of Spearman rank correlation coefficient were drawn for clarity and distinction.According to the plant ecological habits and the interspecific relationship of Spearman rank correlation coefficient test,dominant populations were divided into five major ecological species group.However,when the result of χ2-test was overall taken into account,it could be combined into three ecological species group.It was suggested that the species-pairs with significant correlation could be used in the plant configuration,to be favorable to the formation of relatively stable artificial community,The results could provide basis for the landscape application and plant disposition of the rock plant species.
