The invention discloses a degraded soil ecological simulation land maintenance restoration method which comprises the following steps: mixing any one of crop straws, dry branches and fallen leaves, weeds, humus soil and plant ash with human and animal excrement and urine, and stacking to form a semi-decomposed or decomposed raw material; adding a calcium magnesium phosphate fertilizer, a potash magnesium sulphate fertilizer, polyhalite and/or mineral powder into the semi-decomposed or decomposed raw materials, and uniformly stirring to obtain a mixture; stacking the mixture on the surface of the soil according to a ratio of 300-1000m <3>/mu, flattening, patting, compacting, covering with a film, and stacking; stacking the mixture for at least three months, removing the covering film to obtain a secondary fermentation fertilizer, and then removing at least 98% of the secondary fermentation fertilizer on the surface of the soil to complete remediation of the degraded soil. According to the method, a semi-decomposed or decomposed mixture covers the surface layer of the soil, a special isolation layer is formed by the mixture in a mode of forming humus soil in a simulated nature forest, and the purpose of restoring the soil fertility of the degraded soil is achieved through natural stacking and secondary fermentation treatment.
