The Mu Us Sandy Land belongs to arid to semi-arid regions due to climatic conditions, and the vegetation is basically dominated by plants that are adapted to dry conditions. However, in the Mu Us Sandy Land, as the precipitation decreases from southeast to northwest, the vegetation changes accordingly. For this reason, the Mu Us Sandy Land can be divided into three regions with different vegetation. In the northwestern region, desert-steppe and steppe-desert vegetation can be seen, which are established under very dry conditions, and plants with strong resistance to drought predominate. In the central to southeastern part, typical steppe vegetation is seen that occupies most of the Mu Us Sandy Land. In the southeastern edge, vegetation with transitional characteristics between typical steppe and forest steppe develops. The vegetation of the typical steppe consists mainly of xerophytic and mesophytic plants, while in the northwest desert-steppe or steppe-desert, more drought-resistant xerophytic plants predominate. Typical plant species that make up the grassland vegetation (typical steppe) of the Mu Us Sandy Land are plants that belong to genus Stipa of Poaceae, such as Stipa breviflora and Stipa bungeana, which represent the temperate grasslands of Asia. In addition, many plants of the Artemisia of the Asteraceae family are seen, with the semi-shrub Artemisia ordosica being a representative example (Chen 1983; Kobayashi 1994; Wang et al. 2011b).
