Jiayuguan Caohu National Wetland Park is located in the northeast of the city, located in the Danjilin Desert and the frontier of Mengxin Gobi. It is composed of natural marsh wetlands and artificial reservoir wetlands formed by the Toray River, outcrop spring water and groundwater. It is one of the important wetlands in the Hexi Corridor. The park is rich in warm land and plants, with 66 species of wild high plants of 25 families, 48 genus and 66 species. In the wetland park in winter, the lake water is frozen, and the grasses become yellow, which has a different feeling from other seasons. Gansu is a water-scarce place, and it is really not easy to have such a wetland park. When we arrived, there were no people in the wetland park, and it was very comfortable to walk on the boardwalk. I took a few pictures with a drone. If the ice water is rowed, the lake must be very blue.
