中文摘要	以塔里木河中下游湿地和艾里克湖湿地为研究对象，探讨干旱区湿地生态系统植物群落空间分布格局特征及影响群落分布的主要环境因子。采用双向指示种分析（TWINSPAN）法对研究区植物群落进行分类，并采用无偏对应分析（DCA）法对该分类结果进行验证，定量分析植被与8个土壤环境因子之间的关系。结果表明，调查样方中共出现38种植物，隶属于15科35属。采用TWINSPAN法可将41个样方中植物群落划分为7个类型，这7个群落类型分别以梭梭（Haloxylon ammodendron）、苦杨（Populus laurifolia）、芦苇（Phragmites australis）、胡杨（Populus euphratica）、盐穗木（Halostachys caspica）、刚毛柽柳（Tamarix hispida）、盐角草（Salicornia europaea）为建群种。DCA排序结果表明，土壤含水量和全磷含量是制约研究区域植被分布格局的主要环境因子。
英文摘要	Characteristics of the spatial distribution of plant communities in wetland ecosystems, Lake Eric and the middle and lower reaches of the Tarim River, in arid region and their main influencing environmental factors were studied. The plant communities therein were classified with the two-way indicator species analysis (TWINSPAN) method, and the classification was verified with the detrended correspondence analysis (DCA) method. Relationships of the vegetation with eight soil environmental factors were quantitatively analyzed. In the studied quadrats, a total of 38 plant species were found belonging to 15 families, 35 genera. Using the TWINSPAN method, the plant communities in the 41 quadrats were sorted into seven types, of which each had a constructive species, i.e. Haloxylon ammodendron, Populus laurifolia, Phragmites australis, Populus euphratica, Halostachys caspica, Tamarix hispida, and Salicornia europaea, separately. DCA ordination revealed that soil water content and TP content are the major environmental factors controlling distribution of plant species in the studied zone.
