摘　　要：西隆山是滇南最高峰 ,最高海拔 3 0 74.3m ,跨越中越两国边境线。其北坡在中国境内 ,南坡在越南境内。西隆山 2 0 0 0年被列入国家级自然保护区。西隆山已经查明的高等植物 1 79个科 ,469个属 ,781种。其中 ,国家级保护植物和珍稀濒危植物有 2 3种。在西隆山分布的植被类型有 5种 :山地雨林、季风常绿阔叶林、山地苔藓常绿阔叶林、山顶苔藓矮林和次生植被。人为活动对植物多样性的影响很大 ,该文据此对保护措施提出了建议。Xilong Mountain(22°26′36″～22°46′01″ N,102°32′36″～103°04′50″ E),with the peak 3 074.3 m above sea level,is the highest mountain in southeast Yunnan. The north part of Xilong Mountain belongs to China,and the south one belongs to Vietnam. In 1997,Xilong Mountain was approved as provincial natural reserve. As a new area to botanical study,there are no lists and other botanical literatures for this mountain before. According to the result of two expeditions,179 families,469 genera and 781 species including 23 distributed rare and endangered plants are recognized in the mountains. But the number of species actually distributed in the mountain is higher. 5 vegetation types were found in the mountain,they are:mountane rain forest,monsoon evergreen broad-leaved forest,mountane mossy evergreen broad-leaved forest,mountane top mossy thicket and secondary vegetation. The suggestions on the protection are also proposed.
