Abstract: From 2022 to 2023, a field vegetation survey was conducted in the Songyinxi wetland, Songyang County, Zhejiang Province. The vegetation in the Songyinxi wetland is categorized into 4 vegetation type groups, 9 vegetation types, and 57 plant formations. The distribution of vegetation is determined by the growth habits of the dominant species and is primarily influenced by environmental factors such as substrate, water flow, and water level. The dominant stress factors include ecological pressures, such as invasive alien species, and human-induced factors, including habitat disturbances, environmental pollution, and embankment solidification.
