摘　　要： 应用9种计算方法,对鼎湖山自然保护区2种主要林型———针阔叶混交林和南亚热带常绿阔叶林的种间联结关系进行了分析.结果表明:先用方差比率法(VR)验证整个群落的总体关联性,再以2统计量来确定物种间联结性,然后与种间联结系数(AC)和成对物种间匹配系数(O I)等方法共同分析南亚热带森林的种间关系效果会较好.南亚热带常绿阔叶林研究的结果比针阔叶混交林更精确.对种间联结系数AC出现+1、-1的情形,把a、b、c、d为0的都加权为1后的结果,便于在2个林型间进行比较,更能体现出种间关系的动态变化和延续性,而不是种间关系的突变. A series of techniques which included the analysis of variance, x^2 test, the association coefficient, Ochiai, Dice, Jaccard, point correlation coefficient, a new formula of interspecific association measurement and the t-test of correlation coefficients, together with a 2 × 2 contingency table, was used to analyze the interspecific association of dominant species of lower subtropical monsoon evergreen broadleaved forest and coniferous broad-leaved mixed forest at Dinghushan, south China. The analysis of vailance, the x^2 test, the association coefficient and Ochiai are suitable techniques for the measurement of interspecific association for several different forest communities at Dinghushan. If AC is ＋ 1 or - 1, then a, b, c and d values must be weighted as 1, the result will be even better.
