The basal diameter, height of aerial stem, leaf length at middle stem, leaf width at middle stem, internode length at middle stem, internodes number and panicle length of 30 plants from every population were recorded. The statistics of morphological characters showed that the distribution trends of the averages of morphological characters are similar among populations. However, the coefficients of variation within population of 7 morphological characters were very different. The CV of internodes was largest and the CV of height was smallest within population. F-statistics showed that the differences of all morphological characters among populations were significant (P.01). But the differences among populations were different between different groups. The cluster analysis proved that all populations could be divided into three types: salty reed, freshwater reed and giant reed.

对来自每个种群的30个个体的基径、株高、中部叶长、中部叶宽、中部节间长、节间数、穗长7个形态特征的统计分析表明：各形态特征平均值在种群间的分布趋势相似，但变化幅度不同，株高、叶长等营养特征变化较大大，生殖特征穗长的变化较小；7个形态指标在种群内的平均变异度从大到小依次为中部节间长、中部叶宽、穗长、中部叶长、基径、节间数、株高，种群内的平均形态变异度与生境异质性有关；7个形态指标在种群间均差异显著，但多重比较分析显示显著差异主要存在于BZH、淡水生境种群和盐渍化生境种群之间，在相似生境种群间的形态差异不显著；以形态特征为依据的聚类分析支持将15个种群分为三类：盐生芦苇、淡水芦苇和巨型芦苇。
