Effects of Composite Reclamation Models of Sea Buckthorn, A Pioneer Species in Semi‐Arid Regions, on Soil Quality and Microbial Communities

Land Degradation &Development, EarlyView.
ABSTRACT Open‐pit coal mining severely degrades soil and ecosystem functions, constraining regional sustainability. Vegetation‐based reclamation has therefore been widely adopted as an effective approach to promote soil recovery and ecosystem restoration.

Differences in Dust Emission and Near‐Surface Transport Patterns Among Three Surface Substrate Types

Land Degradation &Development, EarlyView.
ABSTRACT Soil wind erosion is a major driver of atmospheric dust emissions and land degradation. Many studies have examined dust release from different substrates, but differences in methods and units still limit quantitative understanding of how surface conditions and wind jointly control dust emission and near‐surface transport. A closed‐circuit wind
