A Study on the Establishment and Abolishment of Wulan County and Its Jurisdiction

位于丝绸之路北线中段、今甘肃省白银市境内的乌兰县,旋置旋废。始设于周武帝保定三年(562),可能废于建德六年(572);唐武德九年(623)重置;建中四年(783),乌兰县境划归吐蕃。唐乌兰县所辖三乡,西境以白鹿烽(今景泰县上沙沃镇白墩子)为界。一乡,所辖范围即县城所在地及其附近,包括今景泰县五佛乡沿河一带,还可能包括河对岸的靖远县发裕堡及北城滩;一乡,为唐代新泉流域,靠泉水耕作的新泉绿洲(即媪围河谷绿洲区),主要为今景泰县芦阳镇辖境,包括吊沟古城一带;一乡,应即今景泰县上沙沃镇以东白墩子、大圪垯、天涝坝梁等盐泽周边地区。

Wulan County, which was located on the middle section of the northern route ot the bllK tLoaa within today＇s Baiyin City in Gansu Province, and which was established and abolished several times, can be as-sociated with the historical changes at that time to the benefit of academic research. It was first established in the third year of the Baoding er （562） during the Northern Zhou and may have been abolished in the sixth year of the Jiande era （572）. It was reestablished in the ninth year of the Wude era during the Tang dynasty and later came under Tibetan control in the fourth year of the Jianzhong era （783）. In the Tang dynasty, Wulan County bounded the ＂Bailu Beacon＂ on the west and had three seats of jurisdiction spread over three townships： one in charge of the city seat and the nearby area, mainly including the riverside area in today＇s Jingtai and Jingyuan; one in charge of the New Spring Oasis area irrigated by the New Spring in the Tang dynasty （today＇s Yunwei River oasis）, located in the modem town of Luyang in Jingtai; the third covered the salt marsh area to the east of Shawo town in today＇s Jingtai.
