　　为了解生长状况良好的胡杨群落，在塔里木河中游沿岸选择具有代表性胡杨群落，设立1 hm2固定样地，调查分析胡杨林群落结构特征。结果表明：胡杨群落垂直层次优势种较为明显，形成以胡杨+柽柳+芦苇、假苇拂子茅为优势种的荒漠河岸林群落类型；胡杨种群属于稳定型种群，个体数量在不同径级之间分布合理；在不同尺度下，胡杨种群均处于集群分布；胡杨种群在不同发育阶段分布格局由聚集分布向随机分布转变。

In order to understand the growth status of the Populus euphratica community under well-preserved conditions, the 1 hm2 permanent plot was established near the coast of the middle reaches of the Tarim River in the south of Xinjiang. The results showed that: the dominant species of community vertical layers were more obvious, and formed the desert riparian forests types as P. euphratica+Tamarix chinensis+Phragmites communis and Calamagrostis pseudophragmites;P. euphratica populations was stable populations, the number of individuals in the different diameters was reasonable; the spatial distributions of the P. euphratica populations conformed to clumped patterns in different scales; P. euphratica populations changed from clumped pattern to random pattern during their upgrowth.
