Loess Tourism Resource Exploitation Strategy in the Chinese Loess Plateau: A Case Study of White Deer Plateau

Journal of Geography and Geology, 2009
As one of the important geologic tourism resources in the world, the Chinese loess landscape tourism has not beendeveloped deeply enough, which can not fulfill tourists’ tourism demands on different levels. Based on many successfuldevelopment experiences about sand tourism and ice snow tourism, according to the feature of loess environment,geographic ...

An insight into the different responses to salt stress in growth characteristics of two legume species during seedling growth

Frontiers in Plant Science
Legumes play a crucial role in the restoration and utilization of salinized grassland. To explore the physiological response mechanism of Astragalus membranaceus and Medicago sativa seedlings to salt stress, salt stress culture experiments with five NaCl

Evaluation of Sediment Connectivity Indices to Improve the Prediction of the Spatiotemporal Variability of Sediment Yield for a Large River Basin (Wei River, China)

Land Degradation &Development, EarlyView.
ABSTRACT Sediment connectivity between source areas and the main streams or local sinks is a complex and dynamic process, especially in large basins due to multiple heterogeneities and interactions between connectivity components. Sediment connectivity indices are promising tools to investigate sediment transport, especially in data‐scarce or large ...
