摘要
在相邻格子抽样调查的基础上 ,采用X2 检验、联结系数 (AC)和种间共同出现百分率 (PC)等指标 ,分析了福建省永定桫椤群落内主要乔木种群的种间联结性 .结果表明 :除少数种对外 ,绝大多数种群间的联结性不显著 ;在联结性显著的种对中 ,下述 7个种对之间有较高的正联结性 :朴树 野鸦椿、青冈 黄瑞木、青冈 油柿、翻白叶树 拉氏栲、黄瑞木 油柿、青冈 香叶树和楤木 盐肤木 .就桫椤种群而言 ,桫椤与猴欢喜、水团花之间有一定的正联结 ,与广东润楠、黄瑞木、柳叶山茶、朴树和野鸦椿有较紧密的负联结 .图 3参
Based on the data collected from the continuous quadrat grid through sampling method, the interspecific association of main tree populations in Alsophila spinulosa community in Yongding, Fujian, was analyzed by means of X 2 test, association coefficient ( A C ) and percentage of co ocurrence ( P C ). The results show that the interspecific association is not obviously correlative in most of the species pairs. There are closely positive association among Celtis tetrandra and Euscaphis japonica , Cyclobalanopsis glauca and Adinandra millettisi , Cyclobalanopsis glauca and Diospyros oleifera , Pterospermum heterophyllum and Castanopsis lammontii , Adinandra millettisi and Diospyros oleifera , Cyclobalanopsis glauca and Lindera communis , and Aralia chinensis and Rhus chinensis . As for Alsophila spinulosa community, Alsophila spinulosa population is positively associated with Sloanea sinensis and Adina pilulifera , but negatively associated with Machilus kwangtungensis , Adinandra millettisi , Camellia salicifolia , Celtis tetrandra and Euscaphis japonica .
