摘　　要：在城市化进程中,园林景观设计在建造生态森林城市和构建城市环保安全系统中起到重要作用。将成都市区的园林景观体系作为研究对象,对成都市园林景观中的长苞铁杉林乔木层种间尺度效应进行有效研究。先通过综合指数法研究物种多样性的特征,将长苞铁杉林乔木层种间调查作为研究的理论依据,通过利用丰富度指数、Shannon-Wiener指数、Simpson指数及Pielou指数获取综合指数值后,分析成都市园林景观设计中生态环境系统的复杂性,以及乔木层物种的丰富度、均匀度和多样性的平均水平,计算出长苞铁杉林乔木层种间重要值,对长苞铁杉林乔木层种间的尺度效应进行分析,根据方差比率法验证多物种间的相似尺度效应,分析不同类乔木层物种间的相似尺度效应。仿真实验证明,利用文中方法可以有效地分析成都市园林景观中长苞铁杉林乔木层种间的尺度效应。In the process of urbanization,landscape design plays an important role in the construction ofecological forest city and the construction of urban environmental security system.Chengdu citylandscape system as the research object,carries on the effective research of Chengdu city landscape ofTsuga longibracteata forest tree layer species scale effect.The characteristics of comprehensive indexmethod of species diversity,the Tsuga longibracteata forest tree layer species survey as the theoreticalbasis of research,obtained by using richness index,Shannon-Wiener index,Simpson index and Pielouindex,comprehensive index,complexity analysis of ecological environment system of Chengdu citylandscape design,as well as the average level of richness the tree layer species,evenness and diversity,calculate the Tsuga longibracteata forest tree layer species important value,the scale effect of Tsugalongibracteata forest tree layer species were analyzed,according to the verification of similar scale effectamong species variance ratio method,analysis of different types of tree layer species similarity scaleeffect.Simulation results show that the proposed method can effectively analyze the scale effect ofChengdu city landscape in Tsuga longibracteata forest tree layer species.
