摘　　要：基于2×2联列表,应用χ2统计量度量、共同出现百分率和联结系数等公式测定了浙江凤阳山福建柏群落24种主要乔木和22种主要灌木的种间联结性.结果表明,在该区森林植被研究中,以χ2检验为基础,结合共同出现百分率PC和联结系数AC来测定植物种群的联结性,效果较好.福建柏群落中,绝大多数种群间的联结性不显著;在乔木层中,福建柏与木荷、褐叶青冈、猴头杜鹃、厚叶红淡比、香冬青间具有显著正联结;灌木层中,福建柏与吴茱萸五加、扁枝越橘、光叶铁仔、石斑木、香冬青、朱砂根、窄基红褐柃有显著正联结,而与翅柃间具有显著负联结.福建柏造林和更新时对于群落乔木层和灌木层的物种需要一定的选择.Based on the 2×2 contingency table, the interspecific associations of dominant tree and shrub populations of Fokienia hodginsii communities in Fengyang Mountain of Zhejiang Province were studied by different indices. The results showed that the χ^2 test, together with percentage co-occurrence （PC） and association coefficient （AC） was effective to measure the association. In Foteienia hodginsii communities, the interspecific association is not sig nificantly correlative in most of the species-pair. In the canopy layer, Foteienia hodginsii was significantly positive associated with Schirna superba, Cyclobalanopsis stewardiana, Rhododendron sirniarum, Cleyera pachyphylla and llez suaveolens. In the shrub layer, Fokienia hodginsii was significantly positive associated with Eleutherococ cus evodiaef olius , Vacciniurn japonicurn var. sinicurn, Myrine stoloni f era , Phaphiolepis indicua , Ilem suaveo lens, Ardisia crenata and Eurya rubiginosa var. attenuata, but significantly negative associated with Eurya alata. The species of the community＇s canopy and shrub layer should properly chosen for afforestation and regeneration of Fokienia hodginsii.
