Jingyuan (simplified Chinese:靖远;traditional Chinese:靖遠;pinyin:Jìngyuǎn) is aChinese county in the east ofGansu province. It is under the administration ofBaiyin prefecture, and consists of two separate tracts of territory to the north and south ofPingchuan district. The northern tract bordersNingxia to the north. The southern area consists of an irrigated area around theYellow River and the northern area is semi-arid highlands.[3]
The name originated from 'settling down in the borderlands'. Jingyuan belonged to theYiqu kingdom, later becoming part of theQin state. The county was first established during theHan dynasty in 114 BC.[4] During theWestern Wei it was known as Huizhou (会州), the defensive outpost ofHuining County. It was located at the battleground of theNorthern Song dynasty and theWestern Xia. In 1730 the county got its current name. In 1928, Jingyuan was transferred fromShaanxi to Gansu.[5]Jingyuan has extensive coal reserves, part of the Yaojie Formation,[6] as well asPalygorskite clay reserves of 1 billion tons.[7][4]
