Abstract:

The plant species and wetland vegetation types of Health Bridge Wetland Nature Reserve in Beijing were investigated by sampling method. The survey found 280 species (excluding varieties and forms) belonging to 184 genera and 75 families of vascular plants (including cultivated and naturalized plants),of which Potentilla reptans was a new record species in Beijing,and Amaranthus palmeri was a malignant invasive weed. Wetland vegetation consisted of 2 vegetation type groups,4 vegetation types and 29 formation types. Based on the diversity analysis of the main plant formations in the study area,it was found that the Simpson diversity index and Shannon Wiener diversity index of Zizania australis formation and heisanleng formation were significantly higher than those of other formations.
