The invention discloses a plateau environment-friendly unfired raw soil brick and a preparation method thereof; the unfired raw soil brick comprises aggregate, cement, phosphogypsum, raw soil, river sand, water glass, aluminum sulfate, sodium aluminate, calcium aluminate, alcohol, calcium chloride and sodium acetate; and the preparation method comprises material preparation, mixing, molding and vibration. Solid waste building waste concrete is used for replacing natural stone, the phosphogypsum does not need to be pretreated, the consumption is large, mixing forming is carried out at normal temperature and normal pressure, the technological process is simple, energy consumption reduction and environmental protection are facilitated, the content of the raw soil is reduced, and the consumption of the raw soil is reduced. The unfired raw soil brick prepared by the preparation method can meet the requirement of constructional engineering on the strength of a building block, and the test block has relatively stron
