| 摘 要： | 通过对滇西北地区国家重点保护野生植物资源的调查和有关文献资料的查阅,建立了滇西北地区国家重点野生植物保护名录,分析了其保护植物的种类及数量特征、分布特征。结果表明,(1)滇西北国家重点保护野生植物共计41种,隶属于30科38属;(2)水平地理分布从西北部到东南部呈现出递减的趋势,高黎贡山片区为保护植物分布的重点保护地区;(3)垂直分布范围很广,主要集中于海拔1 000～2 500 m的河谷中山湿性常绿阔叶林中。研究结果将为滇西北地区生物多样性保护政策的制定提供理论依据。

| Abstract: | On the basis of investigation and literature review on national key protected wild plants in northwest Yunnan,the species composition,number and distribution characteristics of those protected wild plants were analyzed.The study results were as follows: 1) There were totally 41 national key protected wild plants distributed in northwest Yunnan,belonging to 38 genera and 30 families;2) The horizontal distribution showed the tendency of decline from northwest to southwest,Gaoligong mountain was the key area of distribution;3) The vertical distribution scope was very wide,with the valley mid-montane moist evergreen broadleaved forest of 1 000~2 500 m as the main distribution vegetation.The study results could provide some theoretical basis for policy making on biodiversity conservation in northwest Yunnan. |
