摘　　要：对生长于疏勒河中游重盐碱地的长穗柽柳群落进行调查,并对其群落格局进行了研究。结果发现,柽柳科植物相对其他科植物更适应重盐碱地,长穗柽柳种群为优势种;重盐碱地长穗柽柳的分布符合泊松分布;重盐碱地群落优势种重要值依次为:长穗柽柳0.323、骆驼刺0.215、芦苇0.037、芨芨草0.029、西北天门冬0.018、大花罗布麻0.014;重盐碱地长穗柽柳与骆驼刺具有一定程度的生态负联结。The population of Tamarix elongata Ledeb. in heavy saline soils in the middle reaches of Shule River was investigated and its community structure was also studied. Plants belonging to Tamariaceae are more suitable for heavy saline soils than those belonging to other species, and Tamarix elongata Ledeb. were dominant in heavy saline soil. The spacial pattern of Tamarix elongata Ledeb. was Poisson distribution in the heavy saline soil. The important values of dominant species in the heavy saline soil are listed as follows： Tamarix elongata Ledeb., 0.323; Alhagi sparsifolia Shap, 0.215; Phragmites australis （Car.） Trin. ex Steud., 0.037; Agriophyllum splendens Nevski, 0.029; Asparagus persicus Baker, 0.018; and Poacynum hendersonii Hook. F., 0.014. Dominant negative interspecific ecological association was found between Tamarix elongata Ledeb. and A lhagi sparsifolia Shap in heavy saline soil.
