During the farming era, people were living under remarkable survival pressure, which was even harder for the ethnic minorities living in the mountainous area of Guizhou Province due to its unique land morphology. In this situation, the ancestors of Buyi ethnic group living in the Biandan Mountain Area gave priority to a reasonable response to the survival pressure when they started their settlement construction. When choosing settlement location, they fully took into account the mountain forms, water resources, and the distribution of the valley plateaus. In addition, they considered the valley plateau as the key element while building the “mountain-water-paddy fi eld-woods-village” settlement organism through the general layout design and construction. After a long-lasting evolution, the settlement space was constantly improved due to population growth, adjustments to nature, responses to wars, and communications with the Han people. As a result, attractive human settlements are fi nally formed in this mountainous area.
