Abstract:
The temporal dynamics and spatial distribution characteristics of soil moisture in typical slope and gully of Jiulongquangou small watershed were studied in the hilly and gully region of the Loess Plateau of China. The average soil water content of each slope position showed a wave shape with time, and the change trend was: decreasing, increasing, decreasing and increasing. Due to the catchment in the gully, the average soil water content is the largest in the gully, and it changes more with the seasons. The profile soil moisture content characteristics at various slope positions are increased with the soil depth increasing, and the spatial variability of average soil water content in each layer depth is slightly reduced. The spatial variability of soils in different layers under different slopes is slightly fluctuating. However, due to the recharge of interflow and the consumption of roots, there is a large variability in the middle level of the gully and foot of slope, indicating that the interflow in the study area is a factor that must be considered. On the whole, in the small watershed of the gully region of the Loess Plateau, the topographic conditions affect the distribution characteristics of soil moisture, and the gully has obvious water collecting effect.
