摘要： 通过对新疆82个区划单位的植物特有种现状进行统计分析，结果表明：新疆植物特有种约271种，隶属38科119属。受气候影响，植物特有种的区域分布水热条件较优越的山地丘陵区显著多于荒漠平原区；天山、阿尔泰山、昆仑山及帕米尔高原的山谷为新疆植物特有种的集中分布区；塔里木盆地及吐鲁番—哈密盆地平原区因自然环境条件严酷，特有种分布较少；准噶尔盆地具有特殊的气候条件和植物区系起源，特有种植物分布相对较多，共118种，占总种数的43.54%。

Abstract: The study shows that there are 271 endemic plant species in 119 genera of 38 families in Xinjiang. Under effects of the peculiar landforms of “two basins between three mountains” and the climatic conditions, the endemic plant species are more in the mountains where precipitation is high than those in plains and deserts. The endemic plant species are mainly distributed in the valley in the Tianshan Mountains, Altay Mountains, Kunlun Mountains and Pamirs. The endemic plant species are less in the Tarim Basin and TurpanHami Basin in south Xinjiang due to the severe natural environment; climatic conditions and the flora origin in the Junggar Basin are peculiar in arid northwest China, there are 118 endemic plant species, and they occupy 43.54% of the total in Xinjiang. Geographic distribution of endemic plant species in Xinjiang is analyzed, the formation causes are researched, and it is put forward that the conservation of endemic plant species is important for maintaining the biodiversity in Xinjiang. The results can be referred in further study on floras in Xinjiang.  

Key words: endemic plant species, distribution, biodiversity, Xinjiang
