In order to explore the effect of different proportions of arsenic sandstone on the carbon content of sandy soil, the total organic carbon index of arsenic sandstone and sand composite soil was selected for analysis. The carbon content is the highest, especially in the 0-20cm soil layer. After 9 years of cultivation, the 0-10cm total organic carbon content of each proportion of the composite soil layer is significantly higher than that of the sandy land. The average total organic carbon of 9 years of cultivation Compared with three years of cultivation, it has increased by 68.50%, which is a significant increase. In the early stage of compounding, due to engineering disturbances and disturbance of the natural cultivation process of the soil, the total organic carbon content in the compounded soil has a downward trend. With the later cultivation of the compounded soil, the total organic carbon increased significantly, and the addition of arsenic was greatly increased. This accelerated the natural succession process of sandy soil.
