Ecology of Ulan Suhai Lake in China's Inner Mongolia improved

Solar-powered aerators are used to oxygenate the water that is about to flow into Ulan Suhai Lake at an artificial wetland in Urad Front Banner of Bayannur, north China's Inner Mongolia Autonomous Region, May 31, 2026. The Ulan Suhai Lake is the largest freshwater lake in the Yellow River basin. In recent years, local authorities have taken multiple measures to improve the ecology of the lake area. By making good use of the water replenishment from the Yellow River while strictly controlling sources of pollution, the lake's ecology has been improving year by year. (Xinhua/Li Zhipeng)
