Field experiments were conducted on a loess slope in the Three Gorges reservoir area, and data such as rainfall amount, surface runoff, and soil moisture content were collected and analyzed. The results show that rainfall has a significant impact on landslide stability, and the soil water holding capacity in the landslide area is low, which is prone to surface runoff. At the same time, there is a certain correlation between soil moisture content and landslide stability. When the soil moisture content reaches a certain threshold, landslides will occur. Therefore, in managing loess slopes, we need to closely monitor the rainfall situation, strengthen water and soil conservation work, and improve the stability of loess slopes.【Key Words】Three Gorges reservoir area; loess slope landslide; rainfall infiltration; soil moisture content; stability
