It is also an Autonomous Region in northwestern China,bordering with Inner Mongolia Autonomous Region to the north.The region is one of China??s smallest provincial-level administrative units,only 66,400 sq km in size. NingXia comprises two main geographic regions, one is the plateau and Liupan Shan (Liupan Mountains) in the south, and the other is the plains along the Huang He (Yellow River) in the north. The plateau is part of the larger Huangtu Gaoyuan (Loess Plateau), formed by the accumulation of fine windblown silt known as loess. The climate is continental with hot, dry summers and long, cold, and dry winters.Roughly 34 percent of NingXia??s population consists of minority nationalities, most of who are Hui (Chinese Muslims).
