中文摘要	本文基于雅鲁藏布江流域植被调查数据和环境数据对研究区植被群落组成、物种组成与环境关系进行数量生态学分析。结果表明:(1)采用TWINSPAN 分类法把雅鲁藏布江中上游地区的44个调查样地划分为7个群落类型,分别是垫型蒿+紫花针茅群落、纤杆蒿+紫花针茅+藏沙蒿群落、高山嵩草群落、三角草群落、砂生槐+水栒子+白草群落、冷蒿群落以及金露梅+固沙草群落。(2)DCA 排序显示,样地和物种的分布格局主要受经度和海拔因素的影响。(3)CCA 排序的结果再次表明,经度变化引起的温度和降水的改变是控制整个雅鲁藏布江中上游植被群落类型形成和变化的主要因子,并将自然植被分成了针茅、沙蒿等为优势种的荒漠草原群落(源头地区),固沙草、青藏薹草为优势种的高寒草原群落(中游地区),以及灌丛、农田等植被群落(雅江与年楚河汇流处)。
英文摘要	Based on vegetation survey data and environmental data of the Yarlung Zangbo River Basin, we conducted a quantitative ecological analysis of the vegetation community composition and the relationship between species and the environment in the study area. The results showed that 44 sampling sites and 68 plant species in the study area can be classified into seven subtypes: Artemisia minor + Stipa purpurea; Artemisia demissa + Stipa purpurea + Artemisia wellbyi; Kobresia pygmaea; Trikeraia hookeri; Sophora moorcroftiana + Cotoneaster multiflorus + Pennisetum centrasiaticum; Artemisia frigida; Potentilla fruticosa + Orinus thoroldii. Detrended correspondence analysis(DCA) indicated that both longitude and altitude play important roles in site and species distribution patterns. In addition, canonical correspondence analysis(CCA) revealed that in the upper and middle reaches of the Yarlung Zangbo River Basin, changes in temperature and precipitation caused by longitude are the main factors controlling the formation and transition of vegetation community types. Moreover, natural vegetation could be divided into three types: desert steppe community(source area), alpine steppe community(middle reaches region), and shrub community(confluence of Yarlung Zangbo River and Nyangqu River).
