Other Abstract

Gullies are pervasive topographic features on the Loess Plateau. We selected two typical gullies in the water-
wind erosion region of the plateau to study the effect of gullies on the spatiotemporal variability of soil-water. The
distribution and variation of soil-water storage were evaluated using time-series analysis and classical statistical methods.
Soil-water storage varied with distance to the gully borders. The spatial average soil-water in the study sites was
300 cm from the border. soil-water in the vertical direction was mostly dependent on the vegetation,and the gullies
had little impact. The spatial distribution of soil-water at a slope scale presented different patterns. Strong upland
winds increased the evaporation of soil-water,which rapidly dissipated. Soil-water storage at mid-slope near the gullies
was as high as 949. 9 mm. The bottom of the slopes had soil-water deficits of 4%. Soil-water storage was much
higher in an apricot orchard than in shrubland dominated by Caragana korshinskii Kom. Soil evaporation,vegetation
type,and the gullies increased the complexity of the pattern of soil-water.
