摘　　要：调查研究了新疆境内柽柳属植物的分布与群落类型。在前人工作基础上绘制了新疆柽柳属植物分布图。研究结果表明 ,地表水是柽柳群落繁衍的关键 ,地下水是柽柳群落生存的命脉。水是决定和影响柽柳属植物现代地理分布的关键环境因子。依据柽柳群落所处地形地貌、土壤类型和群落景观等环境特征将柽柳群落划分成 9种不同的生态类型。依据群落间物种组成的相似性系数对群落进行了聚类分析 。In this paper, the distribution and the community types of Tamarix spp. in Xinjiang are investigated and researched. The distribution maps of the Tamarix communities in Xinjiang are charted based on the predecessors' achievements. The results show that in Xinjiang surface water is the key of multiplying the Tamarix communities and groundwater is the lifeblood for the survival of the Tamarix communities, so water resources including surface water and groundwater are the key environmental factors in the modern geographical distribution of Tamarix communities. The Tamarix communities are classified into 9 ecological types based on the environmental features, such as the topographical and morphological conditions, soil types and the landscape of the Tamarix communities. Cluster analysis is used to research the similarity and the correlation of the various Tamarix communities. The characteristics of succession of the Tamarix communities are also discussed in the paper.
