Along with large-scale "Grain for Green" in the Loess Plateau of China, the land-use change significantly affected the soil water content (SWC) and its spatial-temporal pattern. In this study, we investigated the hill slopes, and the effects of different vegetation restoration types (abandoned farmlands and black locust forestlands) on the spatial pattern or heterogeneity of the SWC were explored based on the differences in the slope trends of SWC between two vegetation restoration types. The results indicated that the average SWC of black locust forestland slopes was significantly lower than that of the abandoned farmland slopes in both zones. Furthermore, slope differences in the SWC in the black locust forestlands were lower than those in the abandoned farmland slopes. Along the hill slopes, although the SWC both showed decreasing trends from the bottom to top in the two vegetation restoration types, both types also exhibited certain differences in their trends. The decreasing trend of SWC in the abandoned farmland increased with increasing soil depth. Furthermore, the decreasing trend of the abandoned farmland SWC was more obvious in Shaozhongwan of Chang Wu county than it was in Yangjuangou catchment of Yan an. In contrast, the decreasing trend of the black locust forestland decreased with increasing soil depth. Moreover, the decreasing trend in the black locust forestland from the bottom to top was lower than that of the abandoned farmland. In addition, the variation trend of the SWC along slopes in the black locust forestlands showed no obvious differences between the two zones. In summary, although the different rainfall background would lead to differences in SWC, its variation trend along with the hill slopes including the effects attributed to different vegetation restoration types were similar between the two zones. Moreover, the excessive consumption of soil water by the black locust forestland not only led to soil water deficits but also diminished the variation trend of SWC along the slopes. In contrast, the abandoned farmlands maintained relatively positive SWC and spatial patterns. By analyzing the effects of different vegetation restoration types on the variation trends of SWC along the slopes, the soil hydrological effect of different vegetation restoration methods could be enriched. Moreover, our findings could provide a useful reference for the scientific allocation of vegetation during the "Grain for Green" process based on the slopes.
