摘　　要：种群的数量特征是其自身特性和生境相互作用的结果。通过样方法对昆明市呼马山云南松种群的数量特征进行研究,结果表明:云南松种群年龄结构阴坡为偏稳定型,阳坡和山脊属于增长型;种群密度的生境分布趋势是由阴坡→阳坡→山脊增加;生物量的生境分布趋势是由阴坡→阳坡→山脊减少,阴坡生物量峰值集中在35龄左右,而阳坡和山脊生物量峰值均集中在15龄左右;云南松种群分布格局与其生境没有必然关系,在3种生境(阴坡、阳坡、山脊)下都呈现聚集分布。Population quantity characteristics is a result of their own characteristics and habitat interaction with each other.In this paper,population quantity characteristics of Pinus yunnanensis Franch.in Huma Mountain in Kunming City was studied.The results were as follows： The population age structure located in north slope belonged to stable type.That in south slope and the ridge were both incremental type.The population density increased following north slope→south slope→ridge.The biomass habitat decreased following north slope→south slope→ridge,the biomass peak of north slope concentrated at about 35 ages,but that of south slope and ridge concentrated at about 15 ages.There was no necessary connection between the population distribution pattern and habitats.In the three habitats（north slope,south slope,ridges）,the population distributions present gathered distribution all.
