Stable Isotopic Analysis on Water Utilization of Two Xerophytic Shrubs in a Revegetated Desert Area: Tengger Desert, China
Stable isotope studies on stable isotope ratios of hydrogen and oxygen in water within plants provide new information on water sources and water use patterns under natural conditions. In this study, the sources of water uptake for two typical xerophytic shrubs, Caragana korshinskii and Artemisia ordosica, were determined at four different-aged revegetated sites (1956, 1964, 1981, and 1987) in t...
متن کاملSlope effect on saltation over a climbing sand dune
Results from a three-year study are presented that integrate field work (in Israel), physical modeling (wind-tunnel testing at UC Davis), and numerical solutions of grain trajectories to model and explain sand transport over a climbing dune. Field grain-size analyses of surfaceand saltation-trap materials taken along various positions of the slope suggest that only smaller particles (< 230 pm i...
متن کاملEffects of Sand Dune Stabilization on the Spatial Pattern of Artemisia ordosica Population in Mu Us Desert, Northwest China
Vegetation patterns are strongly influenced by sand mobility in desert ecosystems. However, little is known about the spatial patterns of Artemisia ordosica, a dominant shrub in the Mu Us desert of Northwest China, in relation to sand fixation. The aim of this study was to investigate and contrast the effects of sand dune stabilization on the population and spatial distribution of this desert s...
متن کاملThe Influence of Hydrogeology Characteristics on Sand dune movement (Case study: Daranjir playa)
Introduction About 1/4th of the world deserts is covered with Aeolian sand (McKee, 1979; Ghadiry et al., 2012). Sand dunes are considered as one of the most important geomorphic features of such environments the formation of which shows the abundant resources of sand, the sand-moving powerful wind and the suitable conditions for sediment deposit (Tsoar, 2001; Michel et al, 2018). The most sign...
