Abstract The origin and provenance of eolian sediments such as loess can potentially reveal paleo-air circulation directions that drive temporal changes in climate. these deposits has been mostly assessed by detrital zircon U-Pb geochronology remains debated. Recent studies constraining sediment using only yields a restricted view the overall sources, because commonly records high-temperature t...

The Loess Plateau in China receives lots of attention from around the world. The expansion of bad agricultural practices for hundreds of years aggravated the soil erosion on the Loess Plateau, however, and a lot of efforts were and are being made to reduce the serious soil erosion as well as regional poverty. Agricultural development of the Loess Plateau is still confronted with intricate chall...

Climate generator (CLIGEN) is widely used in the United States to generate long-term climate scenarios for use with agricultural systems models. Its applicability needs to be evaluated for use in a new region or climate. The objectives were to: (1) evaluate the reproducibility of the latest version of CLIGEN v5.22564 in generating daily, monthly, and yearly precipitation depths at 12 stations, ...

The Chinese Loess Plateau is suffering from severe soil erosion. The eco-environmental changes of the plateau have attracted considerable attentions both from scientists and local governments. Aiming at the regional features of eco-environment and main environmental problems of Linfen City, the synthetic evaluation index system including Organism Abundance index, Vegetation Cover index, Water D...

The loess deposits widely distributed in the eastern Tibetan Plateau (ETP) are important archives for reconstructing paleoenvironmental changes and dust transportation history of Plateau. A lack sufficient investigations on source ETP has limited our understanding implications. Quartz luminescence sensitivity holds great potential tracing eolian sources. Numerous quartz have provided new insigh...
