Abstract:Abstracts:Plant species were investigated in the Canglongdao National Wetland Park in August, 2015. The result showed that a total of 350 species of vascular plant belonging to 271 genera and 105 families, which included 115 species of woody plants and 235 species of herbaceous plants were maintained in this park. The dominant species were wild plants including 263 species, and the park had 87 species of plant of introduction and cultivation. From the perspective of the families, the single and small families were the main and Gramineae had the most species including 35 species belonging to 30 genera. From the perspective of the genera, it was dominated by medium and small genera, which constituted an important group of plant diversity in the wetland park and wetland vegetation. This wetland vegetation in the wetland park could be divided into four groups of vegetation type, seven vegetation types, and thirty two formations.
