中文摘要	根据2013年对乌鲁木齐地区典型灌木群落野外50个样地调查的数据,结合双向指示种分析分类方法,从各群落基本特征、物种组成、区系特征、物种多样性等方面对乌鲁木齐地区典型灌木群落结构特征及其多样性进行了分析。结果表明:(1)被调查的50个样地灌木植被群落中共出现了169种植物(其中灌木植物36种,草本植物133种),隶属于118属,31科,其中以藜科、菊科、禾本科等干旱区的表征科居多。灌木物种的植物区系以地中海区、西亚至中亚分布和北温带分布为主。(2)采用TWINSPAN分类方法可将50个样方划分为10个灌木群落类型。乌鲁木齐地区典型灌木群落多样性指数偏低,黑果小檗+宽刺蔷薇+金丝桃叶绣线菊群落的多样性指数最大,群落之间水平差异显著;欧亚圆柏群落、宽刺蔷薇+矮锦鸡儿群落和铃铛刺+喀什菊群落次之;多枝柽柳群落和琵琶柴+喀什霸王群落最低。(3)属于灌丛植被类型的灌木群落,物种多样性指数为草本层>灌木层;属于荒漠植被类型的灌木群落,物种多样性空间结构为灌木层>草本层。
英文摘要	According to the quadrat investigation material and TWINSPAN classification,we analyzed the community structure and diversity of typical shrub community by the species composition,floral feature and species diversity.The results showed that:(1)The investigated plants belong to 169 species (including 36 kinds of shrubs,133 kinds of herbs),118 genera and 31 families.Most plants belong to chenopodiaceae, compositae and gramineae,which were the characteristic families in arid region.The ancient Mediterranean and West Asia to Central Asia and the North temperate distribution pattern are the dominant flora.(2)Using the TWINSPAN method,the typical shrub communities in the 50 plots were sorted into ten types.The shrub community species diversity indexes are generally low,in which the species diversity indexes of Berberis heteropoda+Rosa platyacantha+Spiraea hypericifolia community are larger;and the species diversity index of Juniperus sabina community,R.platyacantha+Caragana pygnaea community and Halimodendron halodendron+Kaschgaria komarovii community are second,Tamarix chinensis+Reaumuria songarica+Sarcozygium kaschgaricum are lower.(3)The shrub community belongs the thicket vegetation and the species diversity indexes of herb are larger than the shrub layer.The community is classified by desert vegetation types,the species diversity indexes of shrub are larger than that of the herb layer.
