摘　　要：经过多年的野外调查和文献资料整理,按照司马永康修订提出的木兰科植物分类系统,对贵州现有木兰科植物种类、组成、分布等进行详细深入分析研究,结果表明:(1)贵州现有木兰科植物10属60种,其中48种野生种、10种外来种、2种存疑种;(2)植物属种构成以含笑属、木莲属、玉兰属为主,约占比例80.0%,单性木兰属、鹅掌楸属、秃木兰属等所占比例仅为20.0%;(3)贵州省为中国西南野生木兰科植物重要分布区,种类仅次于云南(61种),高于广西(45种)、湖南(28种)、四川(26)等省(区);而在分布属数上次于云南(10属),高于广西(8属)、湖南(6属)、四川(5属);(4)水平分布上以黔南和黔北为野生种类分布重点区域,黔中区分布种类最少,垂直分布上主要分布于海拔500~1 000m、1 000~1 500m间,海拔1 500~2000m间分布种类次之,海拔2 000m以上的地段分布种类最少。黔中贵阳市、安顺市、六盘水市为主要引种种植区域。After years of field survey and literature review, according to plant classification system of Magnoliaceaeproposed by Sima Yongkang, plants number, species composition and its distribution in Guizhou Province were ana-lyzed and studied. The results showed that： ①There were 60 Magnoliaceae species with 10 genera in Guizhou , in-cluding 48 wild species’ 10 alien species, 2 kinds of doubt;②in terms of genus, Michelia, Manglietia, and Mag-nolia accounted for 80. 0% , and the proportion of other genus , accounting for 20% ;③Guizhou Province is an im-portant distribution area of Magnoliaceae plants in Southwest China, its species number lower than t（61）,higher than that of Guangi （45）, Hunan （28） , Sichuan （26） , and other province number, lower than that of Yunnan （10）, higher than that of Guangi （8） , Hunan （6）, Sichuan （5） ;④In terms of horizontal distribution,wild species were mostly distributed in Southern Guizhou and Northern Guizhou,and few distribution in Central Guizhou. In terms of vertical distribution, it mostly distributed in in the elevation of 500-1 000m and 1 000 -1 500m,flowed by 1 500 -2 000m,and few distribution Above 2 000m. Guiyang City,An- shun City, and Liupanshui City, were the main introduction areas in Guizhou Provin
