摘要： 千岛湖具有大小不一的岛屿1000有余,为了研究岛屿植物物种的β多样性,对千岛湖中心库 区的10个典型小型岛屿的植物物种进行详查,计算和分析岛屿间植物物种的β多样性,以探明岛屿间 面积及距离对植物物种β多样性的影响 。结果表明 :1)距离对岛屿间的物种分布有显著影响,距离近的 岛屿间β多样性值低,说明物种的相似性高 ;2)面积较大岛屿间的β多样性值存在面积效应,即它们的β 多样性值随着与其配对分析岛屿面积的减小而变大,而各个面积较小岛屿分别对应于一组面积较大岛 屿的植物物种β多样性值的变化趋势没有明显规律 。对植物群落β多样性的研究有利于植物物种多样 性的保护,其规律对生物多样性保护区的建设具有指导意义 。
Abstract: There are more than one thousand islands in One-thousand Island Lake region . To study plant speciesβdiversity,10 typical small islands in the centre of lake were selected . Plant species were investigated on each island,andβdiversity among islands were calculated . Then relationships between distances (among islands) and corresponding value ofβdiversity were analyzed .Results showed that :1) distance had a remarkable effect on the distribution of species . The value ofβdiversity was lower when the distance among islands was closer,indicating high species similarity;2) area effects were found by analyzingβdiversity values on larger islands . For the larger islands,theirβdiversity values increased along with the area decreasing of corresponding islands .βdiversity values of plant species had no fixed rule when the larger islands were mated with smaller islands . The study ofβdiversity of plant communities is benefit to the conservation of plant species diversity,and to guide the construction of biological diversity protected areas .
