Wind speed in spring dominated the decrease in wind erosion across the Horqin Sandy Land in northern China

Wind erosion is the main cause of land degradation and desertification in drylands. Severe wind erosion affects regional ecological security and endangers the health of people. The Horqin Sandy Land is one of the largest sandy lands in China. It suffers from severe wind erosion and is one of the mai...
