摘　　要：为了解两河源自然保护区内珍稀濒危植物资源的现状、地理分布与保护情况,采用资料查阅与实地调查相结合的方法,对两河源自然保护区内的国家级保护和珍稀濒危植物的物种丰富度与垂直分布进行了分析。结果表明:两河源自然保护区内有各类珍稀濒危植物83种,其中国家级保护植物10种;珍稀濒危植物79种,被IUCN收录28种、CITES收录5种,被哈萨克斯坦、阿尔泰共和国、俄罗斯联邦和中国四国红色名录收录49种。在保护区整个海拔梯度内,除了冰雪带其余均有珍稀植物分布,但很不均匀。海拔1000-3200m,珍稀保护植物丰富度随海拔梯度的变化呈典型的单峰曲线,国家级保护植物和IUCN收录的珍稀濒危植物均在1200-1500m达到峰值,分别为6种和19种,各占11种的54.54%和28种的67.86%;而CITES物种在1300-2200m达到峰值,占5种的100%。研究结果显示,受多种因素的影响,保护区内各类珍稀濒危植物分布具有明显区域性,文中据此提出了保护珍稀濒危植物,促进地区生态文明的相关对策。In order to understand the current situation, geographical distribution and the protection of rare and endangered plants in Two-River Source Nature Reserve of Altay mountains, the species richness and vertical distribution of rare and endangered plants were analyzed by methods of literature compilation combined with field surveys. The result show that there are 83 rare and endangered plant species in Two-River Source Nature Reserve of Altay mountains. Among them 11 species are belonged to national key wild plant species emphatically protected in China;79 are listed as rare and endangered plant species;28 species are included in the red list of IUCN(2012);5 species are included in the convention on international trade in endangered species of wild fauna and flora(CITES, 2013), and 49 species are included in Red Data Book of Kazakh SSR, 2002, Red Data Book of Altai Republic, 1996;Red Data Book of Russian Federation, 2008) and Red Data list of China, 2004. The rare and endangered plant species are unevenly distributed between 1000-3200 m in different elevation gradients inside the nature reserve.The richness of the rare,endangered and protected plant species reflects the typical characteristics of the single peak curve along the altitudinal gradient variation. The distribution of the nationally and listed in IUCN Red List plant species reach their peaks between the altitudes from 1200 m to1400 m.There are 6 nationally protected species at this elevation range,accounting for 54.54% of the total 11 species;and there are 19 listed in IUCN protected species distributed between 800-1100 m elevation range,accounting for 67.86% of the total 28 species respectively.However,100% of the 5 CITES listed plant species are distributed between 1300-2200 m elevation range.It is suggested that the distribution of rare and endangered plants has significant regional characters which is influenced by many factors affect. Therefore, some countermeasures related conservation and sustainable development of rear and endangered plant are pu
