The Yunwu Mountain National Nature Reserve, in Guyuan, Ningxia Hui autonomous region, is the only grassland-type nature reserve in Ningxia, as well as the earliest grassland-type nature reserve established in China. It is a natural "treasure trove" for studying the evolution process and laws of typical grassland ecosystems in the semi-arid areas of the Loess Plateau.
