Temperature change is an important aspect of global climate change. By studying the earth temperature at different depths of the composite soil, the vertical belt distribution of the earth temperature is explored, which provides a preliminary theoretical basis for production practice. The temperature of the loess and sand treated 1: 1 is smaller, and the buffer effect on temperature is obvious, and the temperature is higher under this treatment. It can be seen that as the soil layer increases, the buffer effect of the soil on temperature changes. With the increase of soil layer, the treatments with better buffer effect and higher temperature were respectively: soft sandstone and sand 1:2 (5cm), soft sandstone and sand 1:5 (10cm), and loess and sand 1:1 (15cm).
