| 摘 要： | 本文应用Lefkovitch矩阵技术,研究海南岛热带雨林优势种青梅Vatica hainanensis(V.astrotricha)种群数量动态,建立种群增长的矩阵模型,模拟种群增长的可能变化。 计算得出青梅初始矩阵的特征根是1.0004,它已相当接近种群稳定时的理论值1.0,而且种群初始和稳定时的个体分布十分相似,从而证明青梅是一个稳定的顶极种群。种群增长模拟结果表明,在青梅种群生活史中,种子和老龄阶段对干扰不敏感,而具最大繁殖潜力的阶段对干扰最敏感。

| Abstract: | In this paper the population dynamics of dominant tropical rain forest species Vatica hainanenses (V. astrotricha ) in Hainan Island is studied by Lifkovitch's matrix technique,A matrix model of the population growth is developed and possible changes in the population growth are simulated with the model.The dominant latent root for the initial matrix of V.hainanensis is 1.0004 by computing, which is remarkably close to the theoretical value of 1.0 for population stability.The relative distributions of initi... |
