The Spatial Distribution of Wetland Preference of Vegetation in River Type Wetland Protected Area

The spatial distribution of wetland preference of vegetation was analyzed based on the results of actual vegetation maps for six river type wetland protected areas. There are nine to 23 plant communities distributed in the six wetlands. In wetland preference plant communities, there are 16 obligate wetland plant communities (OBW), 10 facultative wetland plant communities (FACW), seven facultative plant communities (FAC), five factultative upland plant communities (FACU), and 15 obligate upland plant communities (OBU). In the central part of the wetland protected area, OBW and FACW are mainly distributed, and in the peripheral area, FACU and OBU are widely distributed. Therefore, in order to continuously maintain wetland vegetation, it is necessary to prevent drying out by managing inflowing water, removing sediment, and securing water flow.
