摘 要: 根据野外41个通过采用样方调查法得到的数据,运用双向指示种分析法(two-way indicator species analysis, TWINSPAN)和除趋势对应分析法(detrended correspondence analysis, DCA)对山西汾河连伯滩湿地植被进行数量分类和排序。TWINSPAN将41个样方划分为7个群丛,即狐尾藻群丛、赖草群丛、旱柳-赖草+小香蒲群丛、白茅群丛、旋覆花群丛、芦苇群丛和狭叶香蒲+芦苇群丛,并分别论述了各群丛的特征。样方的DCA排序结果较好地反映了植物群丛类型与环境因子,尤其是土壤含水量之间的关系。28种DCA排序结果较好地反映了群丛的生境特征,优势种的分布格局在很大程度上决定着植物群落的分布格局。
关 键 词: 生态学;双向指示种分析法;除趋势对应分析;汾河连伯滩;湿地植被

Abstract: The quantitative classification and ordination of wetland vegetations in Lianbo flooding plain of Fen River, Hejin, Shanxi were studied based on the 41 samples using two-way indicator species analysis (TWINSPAN) and detrended correspondence analysis (DCA). The 41 samples were classified into 7 associations, which are Ass. Myriophyllum verticillatum, Ass. Leymus secalinus, Ass. (Salix matsudana-Leymus secalinus+Typha minima), Ass. Imperata cylindrical, Ass. Inula japonica, Ass. Phragmites australis and Ass. (Typha angustifolia L.+Phragmites australis), by TWINSPAN, and the community characteristics of each association were described. The result of the ordination for 41 samples by DCA revealed the relationships between the pattern of these communities and certain environmental factors, especially the moisture in soil. The result of the ordination for 28 species DCA reflected the habitat characteristics and the distribution of the dominant species determined the distribution of the communities in a large measure.
Key words: ecology; two-way indicator species analysis(TWINSPAN); detrended correspondence analysis(DCA); Lianbo flooding plain of Fen River; wetland vegetation
