Coal mine subsidence areas transformed into ecological farmland

Rice seedlings float on a water surface, and green rice fields become unique scenery amid the thousands of acres of a sunken water area. This is a major landscape in the mine subsidence area of Guqiao Town, Huainan City, Anhui Province. Not only does this increase the planting area of rice, but it can also purify the water in the subsidence area, improve the ecological environment, and reduce water pollution.
