摘 要 ：本文运用数学生态学一维格局的数学模式对小兴安岭火烧迹地上红松(Pinus koraiensis)种群自然更新的格局进行了分析和讨论。负二项分布和奈曼(Neyman,n→∞)分布的拟合结果表明,这两种数学模式均可以作为格局的理论分布。但由统计分析推断,负二项分布较之奈曼分布更为理想。研究结果表明,迹地上红松种群的更新格局是聚集强度较高的群团型格局,这一群聚形式有利于种群的自然选择和竞争,是红松种群在一定时期内生存和繁衍的最佳分布方式。

Abstract:The spatial pattern of natural regeneration of Pinus Koraiensis on the burned areas in Lesser Xingan mountain has been analyzed. The Pinus Koraiensis forest communities on burned areas are at very serious level of damage, but the natural regeneration certainly begins with fitting ecological condition as time goes on.The regenerative pattern of Pinus Koraiensis population is aggregation, both Negative Bionmial Distribution and Neyman‘s Distribution(n→∞) are accepted. The former is fitter than the later, so i...
