摘要: 运用2×2列联表χ2检验方法对邵武光皮桦天然林群落16个优势树种进行总体相关性和各种对间的联结性检验,同时利用Jaccard指数测定各种对间的关联度.结果表明,除个别种对外,邵武光皮桦群落多数种群间的联结性不显著且联结程度较低,光皮桦与毛竹、拟赤杨之间存在显著的负关联,光皮桦与木荷、锥栗、马尾松的关联度较高.

Abstract: x2test with 2?2 contingency table and Jaccard indices shows that the interspecific association of 16 dominant species in Betula luminifera communities of Shaowu, Fujian Province was of little significant level with few exceptions. The relationships between B.luminifera and Phyllostachys pubescens ,and B. luminifera and Alniphyllum fortunei were significantly positive,showing that there was a high association degree between B.luminifera and Schima superba, B.luminifera, and Castanea henrgi, and B.luminifera and Pinus massoniana based on Jaccard indices.
