赤皮青冈天然小居群物种多样性与生态位研究
|
摘要
采用群落生物多样性的测定和生态位计算方法,对闽清赤皮青冈天然小居群的物种多样性和乔木优势树种的生态位特征进行研究。结果表明:赤皮青冈群落中乔木层物种有24种,灌木层19种,草本层11种;乔木层中赤皮青冈的重要值、生态位宽度最大,为主要建群种和优势种;群落中主要乔木树种对环境的适应能力具有一致性。
The species diversity of natural small populations and the niche characteristics of dominant tree species were analyzed by using the method of biological community diversity and niche calculation method. The results showed that there were 24 species of tree species in the arbor layer, 19 species of the shrub layer and 11 species of herbaceous layer. The important value of arbor layer was the highest, which was the main constructive and dominant species, with the largest niche breadth. The adaptability of arbor tree species to the environment was consistent.
