摘要: 调查了天津滨海新区湿地野生植物群落,计算出各群落中优势种的重要值,并应用典范对应分析法对湿地植被群落类型及其分布与主要环境因子之间的关系进行了研究。结果表明:1)土壤含盐量、土壤pH值以及滨水距离的差异是形成滨海新区湿地植物分布格局的三个主要环境因素。2)三个主要环境因素之间存在相关关系,滨水距离能够对土壤理化因子的数量和强度进行再分配,间接影响了物种生存状态。三个主要环境因素不仅决定了群落在排序空间中的位置,也决定了群落物种组成。3)优势种的分布与样方的分布格局极其相似,优势种的分布格局在一定程度上决定了群落类型的分布格局。

Abstract: Based on investigating natural wetland plant community of Binhai New District in Tianjin,and calculating the important values of the dominant species pertinent to every community,the study on wetland plant communities and their distribution was carried out.Moreover,the relation between wetland plant communities and the main environment factors was analyzed by means of Canonical Correspondence Analysis.The results showed that:(1)Together with distance to water,the salt content and pH value in soil were the major environment elements which controlled the distribution of wetland plant communities in Binhai New District;(2)There was correlation between the three main environment factors,and the distance to water redistributed the soil physicochemical factors in terms of quantities,which resulted in the existing situation of wetland plants;(3)The distribution of the dominant species was resemble to the one of plots,and the distribution of the dominant species decided the structure of different types of communities to some extend.

Key words: Binhai New District, wetland, dominant species, Canonical Correspondence Analysis
