摘    要:锐齿栎是秦岭中低海拔区域的主要树种之一,对秦岭佛坪、长青和太白山北坡三个区域分布的锐齿栎的组成和结构特征进行分析,结果表明:(1)在佛坪自然保护区,锐齿栎分布范围最大,个体数量多,种群结构表现为增长型;落叶阔叶林将是该区域将来的主要组成类型,锐齿栎和化香树等阔叶树种将成为该区域将来的主要组成成分.(2)在长青自然保护区,锐齿栎分布范围大,个体数量多,种群结构表现为增长型;针阔混交林将是该区域将来的重要组成类型,锐齿栎、铁橡树和华山松等将成为在群落中具有明显优势的树种成分.(3)在太白山北坡,锐齿栎种群分布范围很小,个体数量和幼龄个体较少,种群结构趋于衰退,该地区的锐齿栎林很可能在将来被其他类型所取代.

关 键 词:秦岭  锐齿栎  种群  群落

Abstract:Quercus aliena var.acuteserrata is the main arbor species at the intermediate and low altitude areas in Qinling Mountain.Studies on the composition and structure of population characteristics of Quercus aliena var.acuteserrata were made based on the relevant literature and field surveys at Foping,Changqing and the northern slope of Taibai Mt.The results show that:(1) Quercus aliena var.acuteserrata in Foping National Nature Reserve are widely distributed and its populations have been developing well and present a tendency of increase;Quercus aliena var.acuteserrata and Platycarya strobilacea Sieb. Zucc.will be the most important component of the broadleaved forest in Foping National Nature Reserve;(2) Quercus aliena var.acuteserrata present a tendency of increase in Changqing National Nature Reserve,together with Quercus baroniiSkan,it will be the main component of the temperate coniferous-broadleaved mixed forest,which is one of the most important types of community in this area.Meanwhile,Pinus thunbergii will be the temperate coniferous component which was dominant in the community.(3) The population of Quercus aliena var.acuteserrata on the northern slope of Mount Taibai is small,its distribution is limited,and its population presents a tendency of decline.In the future,Quercus aliena var.acuteserrata is likely to be replaced by other types.
Keywords:Qinling Mountain  Quercus aliena var  acuteserrata  population  community
