Interspecific association of dominant species in Betula luminiferanatural forest communities of Shaowu, Fujian Province

Abstract

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.

Key words: Betula luminifera, Dominant population, Interspecific association, Northwestern Yunnan Plateau, adaptation, Napahai wetland, seed reproduction, atmospheric warming
