【摘要】 本文运用多种分市型对天然次生林群落中各主要树木种群的分布格局进行了拟合研究。结果表明:各树木种群的分布格局多为Neyman型分布及Poission型分布。除了进行空间分布格局的数学拟合而外,还对各种群的分布型指数(聚集指标)如K,C、C、I、m*/m进行了分析,结果表明:各种群的聚集指标从幼树阶段到大树阶段有从聚集向松散过渡的趋势。不同的群落类型中,各种群的聚集指标亦呈不同。文章分析了各树木种群的分布格局的成因,并运用Alees原则及耗散结构理论及自组织理论对其进行了阐释,提出本研究的理论意义与实践意义。更多还原

【Abstract】 Applying several distribution pattern models, the main tree populations in natural secondary forest community have been imitated and researched. The results revealed that the distribution patterns of tree populations mainly belong to Neyman type or Poission type. The analysis results of several aggregation indexs such as K、 C、Ca、I and m*/m, revealed that from sapling to tree,K Varies from small to big, but Ca、I and m~*/m in opposite. In different types of communities, the indexs of populations are different. The reasons for the formation of distribution patterns were analysed. The theory of dissipative structure and self-organization were used to explain these phenomina. The theoretical and practical importance of such kind of research was pointed out.更多还原
