| Abstract: | In order to clarify the spatial and temporal variation and the influencing factors of soil moisture on mountain slopes in the humid subtropical climate zone, taking the mid-mountain concave slopes covered by coniferous forest in the Three Gorges reservoir area as the research object. The soil moisture data of 117 monitoring points at a depth of 0-70 cm in a 5-meter grid during 2019 to 2020 were analyzed by using classical statistics and geostatistics methods. And this study investigated the correlation between the statistical characteristics of soil moisture content and environmental factors and the spatial variability characteristics of soil moisture content in the catchment area of typical concave slopes under wet and dry conditions. The results showed that:(1) Soil moisture of all layers in the catchment area showed moderate variability (10%
