中文摘要	采用样方调查法对察汗乌苏绿洲-荒漠交错带五个不同封育区植被的群落结构和特征值进行调查分析,并运用alpha-多样性指数(Shannon-Wiener指数,Simpson指数,群落均匀度指数E)分析生物多样性变化.对比2008和2009年不同封育区植被盖度,密度,生物量等植物特征值表明,到2009年,2003年荒滩造林封育区,安固滩及青冈滩封育区的植物特征值均有不同程度的提高;在安固滩和青冈滩立地条件及封育年限大致相同的前提下,两年的数据均显示青冈滩封育区物种多样性指标大于安固滩封育区,说明轻度的人为干扰比完全封育对植被恢复效果要好;2003年荒滩造林封育区各项指标远远大于其他各区表明,地形地貌特征,水分空间分布等因素是造成样线间各指标不平衡的一个重要因素
英文摘要	Applying quadrat method, the vegetation of five different fenced areas of oasis-desert ecotone in Chahanwusu was investigated to study the community structure and vegetation feature. The change of biodiversity was analyzed by using the methods of ɑ-diversity index(including Shannon-Wiener index, Simpson index and community evenness index). Comparing vegetation cover, density, biomass and other plants characteristic values of different fenced areas between 2008 and 2009, the result showed that vegetation feature of studied plots increased in varying degree by 2009. Under the premise of site conditions and the enclosure years were roughly the same in Angutan and Qinggangtan fenced areas, two years data indicated that the biodiversity in Qinggangtan is greater than in Angutan which implied that mild human disturbance is better than a complete fencing on re-vegetation. The indicators of 2003-fenced area is far greater than the other areas showed that topography characters, the spatial distribution of moisture and other factors are the important factors in contributing the imbalance between the sample lines
