Aeolian Desertification Status and Its Control in China

AbstractDesertification in China mainly includes the following types: soil erosion, aeolian desertification and salinization. Desertification in most parts of northern China is mainly manifested in land aeolian desertification. Aeolian desertification is defined as land degradation in arid, semiarid and parts of semi-humid regions with the occurrence of blown sand activities (deflation, ground surface coarsening, and sand dune formation, etc.) on former non-desert areas as the main mark resulting from various factors including overusing land and upsetting the fragile ecological balance under the conditions of dry and windy climate and loose sand surface (CCICCD 1994).
