摘　　要：木兰科植物在植物系统分类学上具有重要地位,也是北半球亚热带森林的重要组成树种,主要集中分布于中国西南部和南部。该文系统地研究了四川省野生木兰科植物的形态特性、地理分布特点及其利用价值。结果表明:四川省野生木兰科植物资源丰富,有5属24种1变种,主要分布在川西高山狭谷的东南部,以及盆周山地和川西南,处于现代木兰科的分布、分化和起源中心的边缘;四川野生木兰科中,乔木树种23种,灌木2种;常绿成分13种,落叶成分12种;花色包括红色、淡红色、紫红色、紫色、黄色、淡黄色、黄绿色、白色和乳白色等,有些种类的花具有极浓烈香味;叶形奇异、果实独特、树形优美,乔木的干形好、材质优良、较速生。这些珍贵树种,将在科研、园林绿化、林业等方面具有广阔的应用前景。Magnoliaceae plants play an important role in phytogenetic classification and are significant trees in sub- tropic forests,mainly distributed in south and southwest China.The authors systematically studied the characteristics,geographical distribution and utilization value of wild Magnoliaceae plants in Sichuan Province. Results show that wild Magnoliaceae plants in Sichuan Province are rich.There are five genera,24 species and one variety species,mainly distributed in the southeast of mountains and valleys in west Sichuan,hills around Sichuan Basin and southwest Sichuan.They situate in the edge of the center of the distribution, differentiation and origin of modem Magnoliaceae.There are 23 species of arbors and two species of shrubs, and 13 evergreen species and 12 deciduous species.Their flowers present many kinds of colors,such as red, rosy,amaranthine,purple,yellow,straw yellow,olivinic,white and milky.Some of them have strong fragrance.Their leaves and fruits are unique in shape.Their stem profiles are beautiful.The arbors grow fast with good stem form and high quality timber.These trees will be applied in scientific-research,garden ornament,forestry,etc.
