This study explores the development of compound soil. In this study, different planting years and different proportions of sandstone and sand compound soil were studied, and the total organic carbon content and distribution in different planting ages were studied. The results showed that when the planting period was low, the content of readily oxidized organic carbon and the proportion of total organic carbon in sandy soil was the lowest, and the stability of organic carbon was the highest. The easy-oxidation organic matter of compound soil in the ratio of sandstone to sand 1:2 the content of carbon and total organic carbon is the highest, and the stability of organic carbon is the lowest. When the planting period is high, the content of readily oxidized organic carbon in sand is slightly increased, and the content of readily oxidized organic carbon in other proportions of compounded soil is significantly decreased, the stability of organic carbon increased.
