摘要 【Objective】 This study surveyed wild medicinal plant resources in Qinba Mountainous Area and analyzed flora characteristics of medicinal plants to investigate the distribution of medicinal plants resources. 【Method】 According to the sampling surveys and related documents,36 sample plots were chosen to investigate the distribution of medicinal plant resources and analyze flora characteristics of medicinal plants using the basic principles of flora geography in July to September 2013.【Result】 There were abundant resources of medicinal plants in Qinba Mountainous Area of southern Shaanxi,including 104 families, 268 genera and 361 species, among which 7 species (belonging to 6 genera in 5 families) were gymnosperms,344 species (belonging to 254 genera in 92 families) were angiosperms and 10 species (belong to 8 genera in 7 families) were ferns. Families with 2 - 5 genera and genera with 1 specie were the most with high ratios. There were 9 areal-types and 6 subtypes of families, 13 areal-types and 9 subtypes of genera. The tropical and temperate components were dominant in the areal-types of medicinal plants families and genera,accounting for 93.66% and 81.66%, respectively (except world distribution).【Conclusion】 The medical plants in Qinba Mountainous Area were with various distribution patterns. Temperate and tropical floristic elements were clear in nature. Moreover, the medicinal plants had some old components, but there were less endemic elements.
