摘　　要：对重庆市5个县(区)领春木的群落生态进行了调查研究,通过TWINSPAN分类的结果显示了领春的7个群丛:领春木-山矾-鸢尾群丛;领春木+杉木-三颗针-大百合群丛;领春木-山茱萸+尾叶樱-贯众+紫堇群丛;领春木+灯台树-短序荚蒾-紫花地丁+蛇莓群丛;领春木+腊莲绣球-沿街草群丛;领春木-构树-冷水花群丛;黑壳楠-领春木-蝴蝶花+贯众群丛.利用DCA对32个样方和91个物种进行排序结果均显示:海拔1 200m左右为领春木分布较广的区域.随着海拔降低,领春木分布也在减少,低于800m就难以找到它的踪迹.The Euptelea pleiosperma communities were investigated in five counties of Chongqing.Twoway indicator species analysis（TWINSPAN）identified seven ecological associations：E.pleiospermumSymplocos caudate-Iris tectorum;E.pleiospermum＋Cunninghamia lanceolata-Berberis soulieana-Cardiocrinum giganteum;E.pleiospermum-Cornus officinalis＋Prunus dielsiana-Cyrtomium fortunei＋Corydalis edulis;E.pleiospermum＋Cornus controversa-Viburnum brachybotryum-Viola philippica＋Duchesnea indica;E.pleiospermum ＋ Hydrangea strigosa-Ophiopogon bodinieri;E.pleiospermumBroussonetia papyrifera-Pileacadierei;and Lindera megaphylla-E.pleiospermum-Iris japonica ＋Cyrtomium fortunei.The results of detrended correspondence analysis（DCA）of 91 species in 32 quadrats showed that E.pleiospermum was distributed relatively widely in regions at an elevation of about 1 200 m above sea level and that its distribution was reduced with decreasing elevation.No E.pleiospermum was found at an elevation of800m.
