The Ergun Wetlands were formerly known as the Genhe Wetlands. Located on the outskirts of Ergun Right Banner, they are one of China's larger wetlands with a good level of ecological preservation. The terrain here is flat and open, and the tributaries of the Ergun River flow from here to form a spectacular and beautiful river wetland landscape. The wetlands contain a large alluvial plain and have formed a river delta. The wetlands also include the Genhe, Dulbu and Hawu'er Rivers, their tributaries, their floodplains on either bank, shrubby willows, alkali-salt grasslands and sinkholes.
