浮烟山刺槐种群大小结构及分布格局研究

Studies on the Size Structure and Distribution Pattern of Robinia Pseudoacacia Population in Fuyan Mountain

对浮烟山刺槐种群大小径级结构和分布格局进行了研究。结果表明,研究区内刺槐种群结构基本呈类纺缍形和倒“J”型,存在明显的径级缺失,但种群整体基本处于稳定增长阶段;种群分布格局呈集群分布和随机分布型,但集群和随机分布强度略有差异。

Structure and distribution pattern of Robinia pseudoacacia in Fuyan Mountain were studied. The result showed that the size structure of Robinia pseudoacacia population has two type, the spindle-like form and pour ＂J＂ form,and clear diameter defect, but the population is stable development phase in general. The population distribution pattern is clump and random, but the degree is different slightly.
