Based on the national desertification and desertification monitoring data from 1994 to 2014,this paper summarizes the current status and dynamic changes of land prone to desertification in China in the past 20 years,research results:① the desertification land area in China is generally declining,from 1.7289 million km² in 1994 to 1.7212 million km² in 2014;②desertified land is mainly distributed in five typical provinces(autonomous regions) of Xinjiang,Uygur Autonomous Region,Inner Mongolia,Tibet,Qinghai,Gansu;③the desertification types are mainly gobi,flowing sand and fixed sand;④the degree of desertification gradually changed from very severe desertification to severe,moderate desertification,and moderate desertification to light desertification.At the same time,the reasons for the change of desertification land area in China are analyzed,and the targeted countermeasures are proposed.
