Based on the field investigation and literature review of wetland plants in the planning area of Taiyuan, the result showed that wetland vascular plants belonged to 53 families, 104 genera and 147 species, including 6 families, 6 genera and 7 species in Pteridophyta, 2 families, 2 genera and 4 species in Gymnosperms, 45 families, 96 genera and 136 species in Angiosperm. About the flora distribution, no matter the level of families and genera, the world distribution and temperate zone had a large proportion. It reflected the universality and typical temperate nature of Taiyuan urban wetland plants. Wetland plants were divided into 6 life forms and 3 ecotypes.Wetland plants were mostly native species. There were 12 species of invasive plants belonging to 7 families and 9 genera and the Asteraceae family plants had the largest proportion. There were 2 species of protected species. The wetland vegetation were divided into 4vegetation type groups, 9 vegetation types and 31 formations.
