| 摘 要： | 滇西北位于喜马拉雅山东坡的横断山区域的南部，是横断山区的中心部分，具有明显的立体气候特征。通过实地调查滇西北16个县和查阅大量标本及有关文献，结果表明，滇西北悬钩子属植物资源极为丰富，分布的种类有66种和20个变种，其中发现新分布种6种1变种，15种和6变种为云南特有种，其中10种和4变种为滇西北特有的分布种类。悬钩子属植物在滇西北广泛分布，从低海拔到高海拔均有分布，从总体水平看，草本类分布种类少，仅有6种2变种，分布高度2300 ~ 4200 m，木本类的分布种类有60种18变种，分布海拔740 ~ 4100 m。提出了10种具有育种潜力或直接利用价值的优良果树种质，为种质资源保存和进一步合理开发利用资源提供依据。

| Abstract: | Northwest Yunnan is situated in the south of Hengduan moutains and east slope of Himalayas. It is the centre of Hengduan mountains areas and has typical stereo-climate. This paper reports the Rubus resources in northwest of Yunnan based on field investigation, studies on specimens and literature. It is indicated that northwest Yunnan is very rich in Rubus resources. There are 66 species and 20 varieties of Rubus in northwest Yunnan, among them, 6 species and 1 variety are new distributions to northwest Yunnan, 15 species and 6 varieties are endemic to Yunnan, 10 species and 4 varieties are endemic to northwest Yunnan. Rubus is widely distributed in northwest Yunnan. The lowest altitude of its distribution of the genus in northwest Yunnan is only 740 m and the highest altitude is 4200 m above sea level. Among the known species from northwest Yunnan, 6 species and 2 varieties are herb Rubus, 59 species and 18 varieties are woody Rubus. The distribution of herb Rubus is from 2300 m to 4200 m. The woody Rubus is distributed from 740 m to 4100 m. 10 species of Rubus which have potential cultivation and directly usage values are described in the paper to give suggestion for germplasm preservation and further rational usage of the plant resources. |
