The red-clay sequence on the Chinese Loess Plateau (CLP) was deposited during the late Miocene-Pliocene and is encoded with important information of past climate changes. However, it has received much less study in comparison to the overlying Pleistocene loess-paleosol sequence. In this paper, we review recent progress in characterizing the environmental magnetic parameter-based paleoclimate hi...

With a vast area of marginal land, the Loess Plateau of China is a promising region for large-scale production of second-generation energy crops. However, it remains unknown whether such production is sustainable in the long run, especially under climate change. Using a regional climate change model, PRECIS, we analyzed the impact of climate change on Miscanthus production in the Loess Plateau....

The loess in the arid area of Xinjiang is located at eastern end Central Asia Loess Belt, and paleoclimate research about it great importance for understanding mechanism interaction Eurasian Westerly monsoon system aridity Asia. This review focuses on recent progress concerning spatial distribution, material composition provenance points out shortcomings challenges to dust circulation. Field in...

Abstract Purpose Loess landscapes are highly susceptible to soil erosion, which affects stability and productivity. Erosion is non-linear in time space determines whether soils form or degrade. While the spatial variability of erosion often assessed by either modelling on-site measurements, temporal trends over decades millennia very lacking. In this study, we determined long- short-term rates ...

Loess deposits distributed in southeastern China play an important role for paleoclimate reconstruction of the subtropical regions. These loess-paleosol are mainly spread within middle and lower reaches Yangtze River as well drainage area Huai River. The ages loess paleosol sequences that along not constrained. In this study, standard single-aliquot regenerative dose (SAR) optically stimulated ...

Understanding the mechanism of dust generation is critical for evaluating global cycles nutrient elements and interpreting paleorecords derived from aeolian deposits. Here, we use a novel geochemical tracer, 234U/238U activity ratio that reveals particle comminution age, Sr-Nd isotopes to investigate how silt-sized particles are produced in Taklimakan Desert, major source region having effects ...

Retardation of tritium migration in the Chinese loess media was studied through column experiments by comparison of the migration velocity with other three “non-adsorptive” tracers of Br, Tc, and I. Results showed that the transport peak of Br was 1.25 times earlier than that of tritium when the tracers were simultaneously injected into the column, and the migration of Tc was even 1.60 times fa...

Predicting the probability of the occurrence of a binary outcome or condition is important in biomedical research. While assessing discrimination is an essential issue in developing and validating binary prediction models, less attention has been paid to methods for assessing model calibration. Calibration refers to the degree of agreement between observed and predicted probabilities and is oft...

We present an analysis of the impacts of weather change and large-scale vegetation conservation programs on the vegetation dynamics in China’s Loess Plateau from 2000 through 2009. We employed a multiple lines of evidence approach in which multi-scale data were used. We employed Normalized Difference Vegetation Index (NDVI) data, acquired by the Moderate Resolution Imaging Spectroradiometer (MO...

BACKGROUND Adequate normalization minimizes the effects of systematic technical variations and is a prerequisite for getting meaningful biological changes. However, there is inconsistency about miRNA normalization performances and recommendations. Thus, we investigated the impact of seven different normalization methods (reference gene index, global geometric mean, quantile, invariant selection...
