摘　　要：对辽宁朝阳地区不同退化阶段天然植被群落的乔灌木种类组成进行调查研究的结果表明,样地中比较常见的树种为油松、山杏、花曲柳、黄榆、三裂绣线菊、小叶鼠李、荆条、土庄绣线菊;个体数量较多的树种是油松、小叶白蜡、山杏、柞树、花曲柳、蒙椴、落叶松、黄榆、荆条、三裂绣线菊等。落叶松、油松、五角枫、蒙椴、忍冬等平均胸径或地径及平均高较大,山杏、小叶白蜡、花木蓝、三裂绣线菊、胡枝子等数值较小。除小叶白蜡外,其他乔木树种基本没有分株,灌木树种均有分株,其中大花溲疏、三裂绣线菊、紫丁香分株数较多。综合考量,朝阳地区乃至辽西地区近自然植被恢复适宜采用的乔灌木树种为油松、山杏、花曲柳、黄榆、小叶白蜡、柞树、三裂绣线菊、小叶鼠李、荆条、土庄绣线菊、毛榛子、胡枝子。In this paper,the species composition of trees and shrubs in different degradation stages of natural vegetation communities in Chaoyang area of Liaoning Province was investigated.The results showed that the common tree species in the sample plots were Pinus tabuliformis,Prunus sibirica,Fraxinus rhynchophylla,Ulmus macrocarpa,Spiraea trilobata,Rhamnus parvifolia,Vitex negundo,Spiraea pubescens.The tree species with a large number of individuals were Pinus tabuliformis,Fraxinus bungeana,Prunus sibirica,Quercus mongolica,Quercus mongolica,Tilia mongolia,Larix gmelinii,Ulmus macrocarpa,Vitex negundo,Spiraea trilobata,etc.The average DBH or ground diameter and average height of Larix gmelinii,Pinus tabuliformis,Acer elegantulum,Tilia mongolia,Lonicera chrysantha and so on were larger,while the values of Prunus sibirica,Fraxinus bungeana,Fraxinus bungeana,Spiraea trilobata,Lespedeza bicolor and so on were smaller.In addition to Fraxinus bungeana,other tree species had little ramet,while shrub species had ramet,and there were more ramet for Deutzia grandiflora,Spiraea trilobata and Syringa oblata.The suitable tree and shrub species for the near natural vegetation restoration in Chaoyang area or western Liaoning were Pinus tabuliformis,Prunus sibirica,Fraxinus rhynchophylla,Ulmus macrocarpa,Fraxinus bungeana,Quercus mongolica,Spiraea trilobata,Rhamnus parvifolia,Vitex negundo,Spiraea pubescens,Corylus sieboldiana,Lespedeza bicolor.
