摘　　要：为摸清英山吴家山森林公园杜鹃的分布和生长情况,选择不同海拔设置样方,以杜鹃株数,分枝数,株高、基部盖度,土壤养分等指标进行了分析。结果表明:土壤属于酸性到强酸性类型,适宜杜鹃生长;不同海拔高度样方土壤养分没有显著差异;随着海拔的上升,杜鹃分布密度呈增加的趋势,杜鹃分枝数及基部盖度在最高海拔处显著高于低海拔处,表明本地杜鹃在高海拔条件下生长得更好。研究结果对于认识本地杜鹃生长习性、保护特色生物资源具有参考价值。Five plots at different altitudes in Wujiashan Forest Park,Yingshan County,were selected to investigate the number of Azaleas（Rhododendron simsii）of each plot,and its distribution density was also calculated.Ten individuals in every plot were randomly selected to investigate the number of every tree＇s branches,and the plant height and basal coverage were measured.The soil samples of every plot were collected to investigate its nutrient situation.The results showed that the native soil was from acidic to strongly acidic and suitable for the growth of the azaleas.There was no significant difference in soil nutrient content at different altitudes.With the increase of altitude,the distribution density of Azaleas was increasing,and the number of branches and basal coverage at the highest altitude was significantly higher than that at low altitude,which indicated that the Azaleas in this parkgrew better under high altitude conditions.The results have reference value for understanding the growth habits of local azaleas and protecting local biological resources reasonably.
