Ecological analysis of morphological and genetic variation revealed that:(1) The averages of morphological characters were significantly negatively correlated with WSF (2) Dominant frequencies of some RAPD loci were significantly correlated with WSF (3) The correlation between morphological variation and genetic variation was not significant (4) The cluster analysis based on morphological and genetic evidence supported that all population can be divided into three ecotypes: saltmarsh reed, freshwater reed and giant reed.

相关分析表明：种群内各形态特征的平均值均与水盐联合影响因子显著负相关，但种群内形态变异系数与水盐联合影响因子普遍相关不显著；种群遗传多样性指数与水盐联合影响因子相关不显著，但部分生境倾向型的RAPD位点的显性频率和来自等位酶分析的克隆多样性水平与水盐联合影响因子显著相关；形态变异系数与遗传多样性指数相关不显著，但相关系数均为正值。
