摘　　要：应用双向指示种分析法(TWINSPAN)和除趋势对应分析法(DCA)对茅洲河流域湿地植被进行分类和排序研究。结果表明,茅洲河流域初步统计到湿地植物41科96属126种,TWINSPAN分类将52个样点分为6个群丛,论述了各群丛的群落学特征。DCA排序结果反映了植物群落类型与环境梯度之间的关系,表明影响群丛分布格局的主导生态因子为生境的水分条件。The classification and ordination of wetland vegetation in Maozhou Rivers were studied using two-way indicator species analysis(TWINSPAN)and detrended correspondence analysis(DCA).The results showed that there were 126 species of wetland plants in Maozhou Rivers,belonging to 41 families and 96 genera.A total of 52 samples were classified into 6 associations by TWINSPAN and the community characteristics of every association were described.The DCA ordination reflected the relationship between plant community type and the environmental gradient.The results showed that humidity and soil type were the main factors influencing the structure and distribution of wetland community.
