| 摘 要： | 根据标准地样方频度调查数据,用概率论模型模拟的方法,对比研究了小兴安岭过伐林和原始阔叶红松林中红松种群分布格局.研究表明:在不同类型的原始阔叶红松林中,红松在主林层和演替层中的分布格局各不相同,在过伐林的演替层中红松种群呈现负二项分布格局.

| Abstract: | A study was conducted to compare the distribution patterns of Korean pine populations in over-cutting forests and primitive Korean pine broadleaved forests in Xiaoxing'an Mountains by simulation with models of probability theory according to the data collected from six sample plots.Results show that the distribution patterns of Korean pine in the canopy layer and succession layer are various in different types of primitive Korean pine broadleaved forests,while the Korean pine population exhibits a negative ... |
