甘肃木本植物特有种类及其分布

The endemic wood-plant and its distribution in Gansu

在系统收集整理甘肃木本植物研究成果的基础上,考证特有树种学名,简述其性状、分布、产地及生境。首次查明,甘肃木本植物特有种类共23科31属38种33变种6变型。研究木本植物特有现象,为深入探讨甘肃森林植物区系组成、性质、特点及演变规律提供资料,对保护和利用树种基因资源有着极其重要的意义。

This paper collects and sorts a series of Gansu endemic wood-plant species that add up 38 species,33 varieties and 6 formulae in 31 genera of 23 families.Its scientific name,characteristics,distribution,sources and habitat have been identified.So far the result is the first report about Gansu endemic wood-plant species.It can help for investigating Gansu flora component,characteristic,origination and evolvment rule.It also has an important significance for protection and utilization of these wood-plant gene resources.
