In order to preserve the traditional garden landscape and maintain the harmony between traditional and modern gardens of Inner Mongolia, this study theoretically examined the creation and background elements of Inner Mongolia, and reviewed the nature of the people and the traditional design elements. The results of this study show that: 1) the background factor of traditional garden landscapes was nomadic life in plains, which was a lifestyle of adapting to Mother Nature and promoting mutual existence and survival; 2) Shamanism impacted the views of nature among the ancient Inner Mongolian people; 3) traditional garden landscapes could be categorized into landscapes centered around Mother Nature during the Huns era and those centered around the symbolic landscape during the Genghis Khan era; 4) aesthetic elements of traditional garden landscapes included traditional colors of red, yellow, sky-blue, milky-white, and traditional patterns of external knot, cloud, bull horn, and plain grass. These findings may provide basic data for the creation background and characteristics of traditional garden landscape of Inner Mongolia in the application of the green space design of Inner Mongolia.
