“…Vegetation cover directly affects the soil-moisture regime and thus the hydrological behavior of a watershed. SMC can be higher for forests than for grassland, but not always [ 20 – 22 ]. Peng [ 23 ] reported that the average annual SMC in the Heihe River basin is about 50% higher in spruce forest than in grassland.…”

Drought and shortages of soil water are becoming extremely severe due to global climate change. A better understanding of the relationship between vegetation type and soil-moisture conditions is crucial for conserving soil water in forests and for maintaining a favorable hydrological balance in semiarid areas, such as the Saihanwula National Nature Reserve in Inner Mongolia, China. We investigated the temporal dynamics of soil moisture in this reserve to a depth of 40 cm under three types of vegetation during a period of rainwater recharge. Rainwater from most rainfalls recharged the soil water poorly below 40 cm, and the rainfall threshold for increasing the moisture content of surface soil for the three vegetations was in the order: artificial Larix spp. (AL) > Quercus mongolica (QM) > unused grassland (UG). QM had the highest mean soil moisture content (21.13%) during the monitoring period, followed by UG (16.52%) and AL (14.55%); and the lowest coefficient of variation (CV 9.6-12.5%), followed by UG (CV 10.9-18.7%) and AL (CV 13.9-21.0%). QM soil had a higher nutrient content and higher soil porosities, which were likely responsible for the higher ability of this cover to retain soil water. The relatively smaller QM trees were able to maintain soil moisture better in the study area.

“…Therefore, producing stemflow with a greater amount in a more efficient manner might be an effective strategy to utilize precipitation by reducing the evaporation loss (Devitt and Smith, 2002;Li et al, 2009), acquire water (Murakami, 2009) and withstand drought (Martinez-Meza and Whitford, 1996). However, because stemflow occurs in a small amount, some studies neglected the dynamics of stemflow yield by setting a fixed percentage of incident precipitation in the range of 1-8 % (Dykes, 1997;Germer et al, 2006;Hagy et al, 2006) or even ignored stemflow while computing the water balance of terrestrial ecosystems (Llorens and Domingo, 2007;Zhang et al, 2016). That underestimated its disproportionately high influence on xerophytic shrub species (Andersson, 1991;Levia and Frost, 2003;.…”

Abstract. Stemflow transports nutrient-enriched precipitation to the rhizosphere and functions as an efficient terrestrial flux in water-stressed ecosystems. However, its ecological significance has generally been underestimated because it is relatively limited in amount, and the biotic mechanisms that affect it have not been thoroughly studied at the leaf scale. This study was conducted during the 2014 and 2015 rainy seasons at the northern Loess Plateau of China. We measured the branch stemflow volume (SF b ), shrub stemflow equivalent water depth (SF d ), stemflow percentage of incident precipitation (SF %), stemflow productivity (SFP), funnelling ratio (FR), the meteorological characteristics and the plant traits of branches and leaves of C. korshinskii and S. psammophila. This study evaluated stemflow efficiency for the first time with the combined results of SFP and FR, and sought to determine the inter-and intra-specific differences of stemflow yield and efficiency between the two species, as well as the specific bio-/abiotic mechanisms that affected stemflow. The results indicated that C. korshinskii had a greater stemflow yield and efficiency at all precipitation levels than that of S. psammophila. The largest inter-specific difference generally occurred at the 5-10 mm branches during rains of ≤ 2 mm. Precipitation amount was the most influential meteorological characteristic that affected stemflow yield and efficiency in these two endemic shrub species. Branch angle was the most influential plant trait on FR. For SF b , stem biomass and leaf biomass were the most influential plant traits for C. korshinskii and S. psammophila, respectively. For SFP of these two shrub species, leaf traits (the individual leaf area) and branch traits (branch size and biomass allocation pattern) had a great influence during lighter rains ≤ 10 mm and heavier rains > 15 mm, respectively. The lower precipitation threshold to start stemflow allowed C. korshinskii (0.9 mm vs. 2.1 mm for S. psammophila) to employ more rains to harvest water via stemflow. The beneficial leaf traits (e.g., leaf shape, arrangement, area, amount) might partly explain the greater stemflow production of C. korshinskii. Comparison of SF b between the foliated and manually defoliated shrubs during the 2015 rainy season indicated that the newly exposed branch surface at the defoliated period and the resulting rainfall intercepting effects might be an important mechanism affecting stemflow in the dormant season.

“…Deutsch et al (2010) observaron que la humedad del suelo bajo sequía severa limita la producción de los pastizales templados-fríos, los cambios en los niveles de humedad del suelo variaron en concordancia al grado de degradación del suelo (Snymana & Preez, 2005), siendo la lluvia la única fuente de recarga de agua; la textura, cubierta vegetal, y elevación influyen en el contenido de humedad del suelo (Salve & Allen-Diaz, 2001). La dinámica de la humedad del suelo mostraron tendencias similares en los perfiles del suelo de bosques y del pastizal con secado más intenso en el bosque durante la temporada de crecimiento, posiblemente por la mayor utilización de agua en las capas por los árboles (Hagyó et al, 2006). De manera que la función de los tipos de vegetación es afectada por la distribución de agua disponible en el suelo y la composición florística del pastizal (Breshears & Barnes, 1999).…”

Resumen El presente trabajo fue realizado en el ecosistema de montañas en deterioro de la comunidad campesina Cordillera Blanca, Huaraz-Perú. El objetivo fue desarrollar una propuesta de estudio basada en la aplicación integrada de los índices de la condición del pastizal (C), humedad del suelo (H), caracterización ecohidrológica y mejora del rendimiento hídrico (RH) con "surcos" y "hoyos". La C fue estudiada con el método Parker (1951), la H con el diseño experimental completamente al azar y arreglo factorial (3 técnicas x 6 épocas por parámetro de estudio) y el RH con el aplicativo HEC-HMS. La investigación duró dos años, etapa en la que se estudiaron la mejora de la C y H, atributos base para el mapeo ecohidrológico (Vulnerabilidad, conservación, función hidrológica, retención de agua) y el RH. La C muy pobre no mostró cambios pero sí la H (P=0.000<0.05), siendo los "surcos" superior (14.66%) a "hoyos" (12.95%) y control (10.95%); el mapeo ecohidrológico del territorio (2 449 ha) identificó aptitudes de calidad media (49%), alta (29%) y pobre (22%); y los "surcos" perdieron menos caudal de agua (1.17 m 3 .s-1) que "hoyos" (1.19 m 3 .s-1) y el control (1.20 m 3 .s-1). Se concluye que la caracterización ecohidrológica proporcionó adecuados indicadores para el diseño del plan de conservación, restauración y monitoreo de la microcuenca; los índices C y H son muy confiables y los "surcos" y "hoyos" son técnicas efectivas para la restauración de la función ecohidrológica del pastizal.
