As highly dynamic biomes desert expansion and contraction is influenced by climate and anthropogenic factors with variability being a key part of the desertification debate across dryland regions. Evaluating a major world desert, the Gobi in East Asia, with high resolution s...
متن کاملCrescent Moon Spring: a disappearing natural wonder in the Gobi Desert, China.
Introduction Yueya Spring, or Crescent Moon Spring, is a geological wonder located about 6 km south of Dunhuang city, Gansu Province, northwest China. It owes its name to the shape of the spring, or more precisely, the pond fed by the spring water, which resembles a Crescent Moon (Figure 1). Currently, the pond is about 200 m long in an east-west direction and about 50 m wide. The water surface...
متن کاملSpatial Variability and Stocks of Soil Organic Carbon in the Gobi Desert of Northwestern China
Soil organic carbon (SOC) plays an important role in improving soil properties and the C global cycle. Limited attention, though, has been given to assessing the spatial patterns and stocks of SOC in desert ecosystems. In this study, we quantitatively evaluated the spatial variability of SOC and its influencing factors and estimated SOC storage in a region (40 km2) of the Gobi desert. SOC exhib...
