常春油麻藤地理分布分析和应用研究

摘要

常春油麻藤是豆科黧豆属常绿木质藤本植物.该研究运用Diva-GIS软件,结合海拔高度图层和植被图层绘制了常春油麻藤的地理分布图,分析了常春油麻藤的分布规律和生境特性.结果表明,常春油麻藤在中国34.5°N以南中低海拔(300～3 000 m)地区均有分布,如亚热带森林、灌木丛、溪谷、河边和山坡等；在浙江、广东、广西、四川、湖北、云南、贵州、湖南、江西、陕西、甘肃、福建、安徽等省区及其交界处均有分布；其分布与植被类型和海拔有着密切的关系,分布区的植被类型为亚热带常绿阔叶林和热带季雨林.常春油麻藤作为多用途的园林植物具有较高的药用观赏价值.%Mucuna sempervirens Hems L. Belongs to Mucuna of Leguminosae, which is an evergreen woody vine. By using the Diva-GIS software , the geographic distribution maps of M. Sempervirens were established based on the altitude layer and vegetation layer. The distribution rule and habitat characteristics of M. Sempervirens were analyzed. Results showed that M. Sempervirens was distributed below 34.5 °N with the altitude of 300-3 000 m in China,such as the subtropical forests,bushes,streams and hillsides. It grew in Zhejiang,Guangdong,Guangxi,Sichuan, Hubei, Yunnan, Guizhou, Hunan, Jiangxi,Shaanxi,Gansu,Fujian and Anhui Provinces of China. Its geographical distribution and vegetation type were closed affected by the altitude. The vegetation types in distribution region were mainly subtropical evergreen broadleaved forest and tropical seasonal rain forest. As an all-purpose ornamental plant,M. Sempervirens had relatively high medicinal value and ornamental value.
