Abstract

In this study, the soil moisture among 8 typical types of vegetation is investigated and compared during 3 rainy seasons to evaluate the ecohydrological effect of vegetation restoration in the semi-arid Loess Plateau of China. The results show that soil moisture content decreases drastically after vegetation restoration, with no significant difference in near-surface soil moisture among the vegetation types but significant differences in the sub-surface and deep soil layers. It is highlighted that introduced vegetation consumes excessive amount of soil moisture and induces temporally stable soil desiccation, threatening the sustainability of vegetation restoration. The study results suggest that the current planting density of introduced vegetation is too high in specific cases and should be optimized with local soil moisture conditions in semi-arid regions
