摘　　要：本研究利用梅河口市国有林总场森林资源调查复位样地数据,分析了天然次生林中紫椴的种群分布格局。结果表明:种群结构近似呈倒“J”型分布,属于增长型种群;种群中林冠下层和上层个体数量较多,中层个体数量较少,是典型单层林分特征。种群分布格局随径级增加逐渐从聚集分布转为随机分布。Based on the resetting plot data of forest resource survey in State-owned Forestry Farm of Meihekou City,the population distribution pattern of Tilia amurensis in natural secondary forest was analyzed in this paper.The results showed that the population structure was approximately inverted J-shaped distribution and belonged to a growing population.In the population,there were more individuals in the lower and upper canopy,but fewer individuals in the middle canopy.That was a typical single-layer stand characteristic.The population distribution pattern gradually changed from clumped distribution to random distribution with the increase of diameter class.
