From the south to the north, the lands of the county run from the main range of the Kunlun Mountains (which forms the border with the Tibet Autonomous Region) to the middle of the Taklamakan Desert. The southernmost area of the county includes the northern side of part of the Ulugh Muztagh range (the main range of the Kunlun), and a section of the Altyn-Tagh range which runs roughly parallel to the main range of the Kunlun. Most of the county population lives in the northern foothills of the mountains, in the oases watered by snow-fed rivers.
