中文摘要:
      对渭干河—库车河三角洲绿洲盐生植被进行双向指示种分类和模糊数学排序，结果显示：以柽柳和芦苇为优势种的群落Ⅴ具有最强的耐盐能力；以柽柳、盐穗木和盐节木为共优势种的群落Ⅲ耐盐能力次之；以梭梭为单优势种的群落Ⅳ耐盐能力相对较弱；其他植物群落则属于中间过渡类型。柽柳、盐穗木在高盐环境下，具有很强的种间竞争能力，是绿洲盐渍化环境下的优势物种；芦苇具有很强的生态适应能力，常常成为其他群落的重要伴生种。同时认为，土壤盐分是土壤化学因子中影响渭干河—库车河三角洲绿洲盐生植被分布的主要因子。
英文摘要:
      The distribution changes of Halophytic Vegetation were studied by two-way indicator species analysis(TWINSPAN) and fuzzy set ord ination(FSO) in the Delta Oasis of the Weigan and Kuqa Rivers. The results indicated that community Ⅴ with Tamarixram osissina and Phragm ites australis as the dominant species has the strongest ability of adapting to saline, and community Ⅲ made up of Tamarixram osissina, Halostachys caspica and Halocnemum strobilaceum as altogether the dominant species has the strong ability of adapting to saline, while community Ⅳ with Haloxylon ammodendron as single dominant species has weak ability of adapting to saline, and the other communities were the middle type. Tamarixram osissina and Halostachys caspica under high salty environment has very strong inter-specific competition ability, which are dominant plants under the oasis soil salinity; Phragm ites australis which has very strong ecological adaptivity becomes an important companion species in other communities frequently. It is also believed that the soil salinity is the main soil chemical factor determining the distribution patterns of halophytic vegetation.
