摘　　要：采用TW INSPAN多元分析方法将云顶山自然保护区58个群落样方划分为:华北落叶松+白桦-金银忍冬-披针苔草群丛;白杄+华北落叶松-土庄绣线菊+金花忍冬-披针苔草+小红菊群丛;白桦-土庄绣线菊-紫苞鸢尾群丛;白桦-美蔷薇+金花忍冬-小红菊群丛;油松+辽东栎-金花忍冬+黄刺玫-披针苔草+小红菊群丛等13个群丛。应用DCA排序的结果表明:DCA第一轴从左到右坡向的变化趋势为阴坡→半阴坡→半阳坡→阳坡;DCA第二轴从上到下海拔有逐渐升高的趋势。68个优势种的DCA排序图所反映出的结果与样方排序图所反映的结果相一致。Based on the datasets from the field,58 quadrats in the plant communities of Yundingshan Nature Reserve,Shanxi were classified into 13 associations by TWINSPAN,including Ass.Larix principis-rupprechtii＋ Betula platyphylla-Lonicera maakii-Carex lanceloata,Ass.Picea meyeri＋ Larix principis-rupprechtii-Spiraea pubescens＋ Lonicera chrysantha-Carex lanceloata＋ Dendranthema chanetii,Ass.Betula platyphylla-Spiraea pubescens-Iris ruthenica,Ass.Betula platyphylla-Rosa bella＋ Lonicera chrysantha-Dendranthema chanetii,Ass.Pinus tabulaeformis＋ Quercus liaotungensis-Lonicera chrysantha＋ Rosa xanthina-Carex lanceloata＋ Dendranthema chanetii,et al.The ordination results of the communities from DCA were as following：The first axis of the DCA ordination indicated the tendency of slope change was from the sunless side to the sunlit side.The second axis reflected the change of altitude.Moreover,the ordinations of the 68 dominant species and 58 quadrats showed they shared some similarities.
