中文摘要	在野外调查的基础上,结合有关文献和植物标本资料,对乌鲁木齐市生态屏障的东南部"荒山"的种子植物区系进行分析.结果表明:该地区种子植物共有42科180属261种,植物区系特点是:区系组成丰富,优势科明显,科属比例高,种相对偏少;地理成分复杂,分布类型多样;特有种贫乏,区系起源年轻;群落优势种和建群种的生活型、生态型都是旱生、超旱生半灌木以及多年生草本,属于温带荒漠性质.
英文摘要	Located in the northwest piedmont of the Bogda Mountain at southeast of Urumqi, the deserted mountain (43°40’～43°50’N, 87°34’～87°45’E, 900～1200m a. s. 1.) is a typical temperate gravel desert, it is about 30km in length, and its area is about 2200hm~2; the annual temperature is 7.8℃, winter is long and cold, but summer is short and hot, and the annual precipitation and evaporation are 341.7mm and 1756.8mm respectively; the plant growth, structure, distribution and biomass of vegetation are strongly affected by drought. In this paper, the flora of seed plant in the deserted mountain in northwest of Urumqi, is researched based on the filed-investigated data, specimen data and related literatures. The results show that there are 261 species of seed plant in 180 genera and 42 families in the study area. The local flora is characterized by the relatively abundant floristic components, significant dominance, high proportion of families and genera, less species, complicated geographical elements, diversified distribution types, poor endemic species and young origination. In the plant communities, the life-form and ecological form of the dominant and community-building species are all xerophyte subshrubs and perennial herbaceous plants, belonging to the temperate desert component. The local flora is representative in the flora in northwest piedmont of the Bogda Mountain.
