“…Canto et al (2011) also showed a non-lineal effect similar to that of Flores et al (2004) between a runoff area with the production of sediments, even though this non lineal effect could be modified by soil coverage and other soil and drainage area characteristics (Liu et al, 2012;Delmas et al, 2012;Descroix et al, 2008). With a precipitation of about 1019.3 mm, a substantial reduction was observed in the amount of runoff in accordance with the measurement scale, such as show in Figure 12.…”

“…The concentration of rainfall in the summer, together with high temperatures, is conducive to crop growth . Three consecutive years of meteorological data indicate that the period of this study (July to September) is the main period of precipitation for the year, accounting for approximately half of the annual precipitation (Liu et al, 2012). As shown in Fig.…”

“…1). The total area was 2.02 km 2 , with slope gradients ranging from 10°to 30°and elevations ranging from 1050 to 1298 m, and represents a typical loess gully and hilly geomorphology (Liu et al, 2012). The area has a semi-arid continental climate with a mean annual precipitation of 498 mm and a mean air temperature of 10.6°C during the past 20 years (1988)(1989)(1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007).…”

“…Addressing the trade-offs among water availability, grain production and carbon sequestration is the basis for ensuring the sustainable provision of ecosystem services in the Loess Plateau and requires a detailed understanding of the eco-hydrological processes involved. The patterns of rainfall common in the Loess Plateau are characterized by high intensity rainfall leading to an excess of water in a short period of time (Liu et al, 2012). A high runoff ratio enhances soil erosion and reduces soil moisture input.…”

a b s t r a c t a r t i c l e i n f oImplementation of the Grain-for-Green project has resulted in significantly increased vegetative cover on the Loess Plateau of China during the past few decades. The plant communities influence soil moisture recharge and usage processes, particularly the input process, which is directly related to transformation of the limited precipitation into available soil water in the semi-arid Loess Plateau. A study to measure soil moisture dynamics of typical land cover types associated with precipitation events was conducted in a re-vegetated catchment area. Smart probes were inserted at 6 different depths below the ground surface under grass (Andropogon), subshrub (Artemisia scoparia), shrub (Spiraea pubescens), tree (Robinia pseudoacacia), and crop (Zea mays) vegetation to record volumetric soil moisture at 10-minute intervals for a period of 60 days during the growing season in 2011. The advance of the wetting front and total accumulated infiltrated water were measured. The rainfall events were sporadic with widely different intensities, and the soil moisture was replenished mainly by 3-4 heavy precipitation events during July and August. The mean soil moisture content profiles of the 5 vegetation types can be ordered as crop > grass > subshrub> tree> shrub and this relationship displayed time stability. The different land cover types clearly influenced the water infiltration and water input amounts in the re-vegetated area. The subshrub site showed the highest total infiltration amount (164 mm) with precipitation (227 mm) during the study period. The grass site had an infiltration amount of 156 mm. The tree site had a total precipitation of 154 mm and an infiltration amount of 97 mm. The infiltration amount was 136 mm for the shrub site and was the lowest (83 mm) for the crop site. Natural grasses displayed a rapid infiltration rate and the wetting front was able to reach a greater depth.

Soil water depletion and recharge under different land cover in China's Loess Plateau

Vegetation restoration can greatly influence water infiltration and root water uptake depths in semi-arid regions. Soil water dynamics within different vegetated/non-vegetated land cover patterns were studied over time from 2008 to 2013 in an erodible small watershed on the Loess Plateau of China. Results showed that distinct differences in soil water dynamics and water balances existed among different vegetation types. Soil water recharge depths extended deeper than 5 m under bare land and farmland, but introduced forage (alfalfa) and shrub (caragana) species depleted the soil water stores in the 0-to 6-m layers within a few years, prevented deep soil water recharge and exhibited negative water balances. Local food crops can maintain a sustainable soil water balance although there was low productivity. Native grasses should be the best land use type for this region based on the soil water balances observed in this short field study. Because it was difficult to avoid soil desiccation under introduced vegetation, vegetation with high water demands should be combined with shallow rooting plants, and water-saving methods should be taken into account.
