The Horqin Desert ( 科尔沁 沙漠 , Ke'erqin Shamo / 科尔沁 沙地 , Ke'erqin Shadi ) is located in the east of Inner Mongolia in the People's Republic of China in the administrative area of ​​the city of Tongliao . It is an arid to semi-arid area within the Horqin steppe region, mostly on an alluvial plain on the middle and lower reaches of the Xiliao He ("Western Liao River").

Due to the relative proximity to the sea and under the influence of the summer monsoon , the area receives a relatively high amount of rainfall compared to other Chinese arid regions, especially in July and August. The mean annual rainfall amounts to 315 to 490 mm and the annual potential evaporation 1,800 mm. Especially from March to May, strong winds cause sand storms and dust eddies .

By over cultivation , deforestation for firewood and overgrazing occurred in the second half of the 20th century to a progressive desertification in the Horqin steppe. In 1959, the Horqin Desert had an area of ​​42,300 km 2 . In the period from 1975 to 1987, it expanded annually by 1,142 km 2 and in 1985 reached 62,000 km 2 . By 2010 it decreased again to 52,300 km 2 . Ninety percent of its total area consists of solid and semi-solid dunes.
