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.

Abstract: | Using variance ratio (VR)?χ2 test by "2×2"contingency table,the association coefficient (AC) and the other 2 formulae,iePCC 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 analyzedThe studies showed that the dominant populations,such as Myuyuanensis 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 |

Keywords: | Manglietia yuyuanensis Law specie pair interspecific correlation |
