摘　　要：以塔里木河下游人工植物群落为研究对象,调查了重建后植物群落的群落特征,分析了重建后植物物种多样性的变化规律。结果表明:重建后物种数增加了8种,物种丰富度S、Shannon-Wiener指数、Pielou均匀度指数、Simpson指数、盖度都有了不同程度的提高,而生态优势度指数SN有所下降,意味着重建区内物种多样性、群落的均匀度均有不同程度的提高,重建已达到了初步的成效。With artificial plant community in the lower reaches of Tarim river as research object, the characteristics of plant community after vegetation reconstruction were surveyed and the change law of the species diversity in plant community after vegetation reconstruction was analyzed. The results showed that the species number had an increase of 8 species and the index of species richness, Shannon Wiener, Pielou uniformity, Simpson index and vegetation coverage were all increased to different degree, while the ecological dominance index SN was decreased. This meant that the species diversity and community uniformity had been increased to different degrees, and the vegetation regeneration had got a primary effect.
