| 摘 要： | 应用TWINSPAN和DCA相结合的方法，对滹沱河流域湿地植被74个样方进行分类和排序，将湿地植被分为16个群丛。DCA排序第一轴反映土壤含水量梯度，第二轴反映土壤类型的变化。主要优势种的DCA排序图与样方的DCA排序图有很大的相似性，优势种的分布格局在很大程度上决定着植物群丛的分布格局。 |

| Abstract: | TWINSPAN and DCA were combined to classify and collate seventy five quadrats of the wetland vegetations in the Hutuo River into 16 associations. The first axis in the ordination by DCA expressed the gradient of soil moisture while its second axis depicted the changes of soil types. The ordination diagram of the dominant species by DCA was similar to the one of the quadrats by DCA to a large extent and the distribution of the dominant species determined the distribution of the associations in a large measure. |
| Keywords: | TWINSPAN DCA wetland vegetations associations |
