中文摘要	通过2012年8月与2013年5月两次对研究区域进行野外考察,采集和整理鉴定约200号400余份维管植物标本,对新疆巴里坤北部界山植物区系进行了研究。结果表明,新疆巴里坤北部中蒙边境界山属于典型的干旱山区,植物种类十分贫乏,种子植物仅有29科69属88种。该植物区系中,大科不多,藜科是本地区第一大科和优势科(12属19种),其次是禾本科、菊科、蒺藜科、豆科等(含27属32种); 而单属科、单种科所占比例分别高达62.07%和44.83%。该区系含2 ~ 5种的寡种属有13属(含32种),而单种属高达56属,占本区植物属、种总数的81.16%和63.64%,是本地区植物属的主要组成部分,该区自然环境非常恶劣,多数的科与属仅有1种。本区植被稀疏,呈片段式分布,以旱生和超旱生植物为主,个别小区域分布有少量湿生或盐生植物,有小片胡杨。本地区无典型的天山与阿尔泰山的植物成分,与西邻的北塔山也有明显不同,而与准噶尔盆地的植物较为接近。植物区系具明显的温带性质,与地中海区系联系紧密。
英文摘要	Based on the field investigation in August,2012 and May,2013,more than 400 specimens were collected and identified,we analyzed the floristic of vascular plants. This result shows that the border area between northern Balikun in Xinjiang and Mongolia is a typical arid mountain, there are 29 families,69 genuses,and 88 species,plant species are few. In the flora, there are few large families,and Chenopodiaceous is the largest and the dominant families (12 genuses and 19 species), followed by 4 families include Poaceae,Compositae,Zygophyllaceae,and Fabaceae (27 genuses and 32 species). While the single genus of families, the proportion of single-species family are as high as 62.07% and 44.83%; minor-species genera that contain 2 - 5 species are 13 genuses(32 species);single-species genera which are up to 56 genuses,occupy 81.16% and 63.64% of the total number of genaras and species separately in the region, is a major component of the plant genus, this shows the natural conditions is very harsh and only 1 species of most families and generas distribute in this area. The vegetation of this area is sparse and usually distributed fragmentally. Xerophytic and super xerophytic are the major plants,besides, there is a little amount of wet or halophytes distributed in some individual small area,even a small field of Populus euphratica. The region is no typical Tianshan and Altai plant components,also different significantly from west Beita Mountain,closer to Junggar Basin. Flofistic element with obvious temperate characteristics,closely linked with the Mediterranean area.
