Different types of vegetation restoration in the Loess Plateau of China affect the soil water content on slopes. Black locust forestlands have lower soil water content compared to abandoned farmlands. The slope differences in soil water content are also lower in black locust forestlands. Both types show decreasing trends in soil water content from bottom to top, but the trend is more pronounced in abandoned farmlands. This study helps understand how different vegetation restoration methods impact soil water content on slopes, with abandoned farmlands maintaining soil water better than black locust forestlands.
