摘要
本文试用空间差异代替时间变化的方法,分析了贵阳喀斯特山地云贵鹅耳枥种群的动态特征。结果表明,随着种群个体的增大和群落的演替进程,种群分布格局由集群型过渡到随机型,种群大小结构由增长型过渡到衰退型,种群密度呈现负增长。云贵鹅耳枥种群的研究有助于探讨喀斯特森林植物种群生态学研究中的一些理论问题,同时,对于喀斯特森林经营管理和保护具有一定的实践意义。
In this paper, the dynamics of pubescent hornbeam populations in karst mountain of Guiyang are analysed by using the method of substitution of space for time. The results show that the spatial pattern changes from clumping type to random type, the size structure changes from growing type to declining type and the population density tends to have a negative increase, along with the population development and the succession of community.The study on pubescent hornbeam population can not only throw some light on some theoretical themes in plant population ecology studies of karst forest, but be also of practical significance for karst forest management , utilization and preservation.
