摘要:应用方差比率(VR)、卡方(χ2)检验、联结系数(AC)、点相关系数PCC和r等指标对乳源木莲群落中乔木层、灌木层物种各种对的种间联结性进行研究,结果表明:23个乔木层种群在总体上存在显著的正联结,且乳源木莲、拉氏栲、栲树等优势种与其它树种形成种对正联结的比例均比负联结的大,表明其它大部分树种易与这些优势种群混生,形成相对稳定群落.灌木层23个种群间的总体联结性也表现出正联结,并达到显著水平.
Using variance ratio (VR)?χ2 test by '2×2'contingency table,the association coefficient (AC) and the other 2 formulae,iePCC and r,the interspecific correlations of 23 major varieties of the treelayer and the shrublayer in the community of Manglietia yuyuanensis Law were analyzedThe studies showed that the dominant populations,such as Myuyuanensis Law,Castanopsis Lamontii and Castanopsis fargesis,formed more species pairs of positive association than those of negative assocition,which indicated that a lot of population could mixed with those dominant populations;there was remarkable positive relation among the major population of shrublayer in total
