摘  要:
依据文献资料,收集125种药用植物作为中国重点保护药用植物地理分布特征研究对象。结果表明,中国重点保护药用植物区系成分有15个分布型和4个变型,在植物界分布广泛,区系成分较为复杂;在水平分布方面,四川省分布的重点保护药用植物数目最多,约有46~60种;分布有16~30种和31~45种药用植物的省级行政区域分别有14个和13个,分别占总省份数目的 43.75%和40.63%;在垂直分布方面,呈现出一个开口向下的抛物线形分布,高峰基本集中在海拔800~1 400 m区间,其重点保护药用植物数目为48~52种;多年生草本植物在中国重点保护药用植物中占的比例最大,达69.6%;根和根茎类在药用部位方面所占比例最大,达56%。因此,加强对国家重点药用植物的保护、特别是对珍稀濒危野生物种的保护迫在眉睫。

摘  要:
125 species of medicinal plants were collected as the national key protected medicinal plants in China from present literatures. The results show that. The floristic elements are relatively complex of the national key protected medicinal plants in China, and there are 15 distribution zones and 4 variable types,which was widely distributed in plant kingdom. In horizontal distribution, the number of 46 to 60 species in Sichuan province was the most, the number of 16 to 30 species and 31 to 45 species' administrative province are 14 and 13 respectively, accounting for 43.75% and 40.63%. The numbers of the national key protected medicinal plants present a opening down parabola, and the highest peak was basically concentrated in the 800 to 1 400 m range, whose numbers of the national key protected medicinal plants are from 48 to 52. The ratio of perennial herbs in medicical plants was most, accounting for 69.6%. And the ratio of root-like or rootstalk-like in the national key protected medicinal plants in China was most, accounting for 56%. The protection of the national key protected medicinal plants in China shoud be strengthened, especially for rare and endangered wildlife species.
