摘要
利用x2 检验和Spearman相关系数公式研究了重庆四面山常绿阔叶林群落中 2 2个主要乔木种群的种间联结和相关性。对测定结果的生态学意义进行了分析 ,并依据测定结果 ,将 2 2个种群划分为
Using ~{*+~}x2~{*+~}-test and Spearman's rank correlation c oeffic ient(R) formula,the interspecific association and correlation of 22 main tree po pulations in the evergreen broadleaf forest in Simian mountain were investigated .The ecological significance of the results of ~{*+~}x2~{*+~}-test and R formula has been analyzed,and based on the results of ~{*+~}x2~{*+~}-test and R formula,the 22 ma in tree s pecies can be dirided into 4 ecological species groups.
