Abstract:: Land desertification is one of the most serious global ecological environment problems nowadays, it limits the social and economic development.To understand accurately the concept of desertification is the premise and foundation to control land desertification.The authors present and review the different points of desertification concept, and analyse the indicators of the degree of desertification, think that desertification is environmental formation or development of sand desert with the appearance of desert-like landscape on ground surface in "unoriginal sand desert areas", and means the extension and intensification process of sand desert conditions.At last, the authors suggested that theoretical research of desertification, such as the concept, types, cause and distribution of land desertification, is future reinforced.
