东晋建元元年（343 年），前凉张骏以狄道为降狄道，属武始郡①。不久复曰狄道②。段案：
以建兴34 年（346 ）张骏薨为改名时间。治所在今甘肃临洮县。

①《十六国春秋》卷72《前凉录三》张骏条：“建元元年骏田于建西、.石县。秋九月改.石县为金泽县，置狄道县，分属凉州，又以狄道县立武始郡”。雍正《甘肃通志》卷3 上《建置沿革》临洮府狄道条：“前凉张骏改置武始郡，改县曰降狄道。后魏属武始郡。隋开皇初郡废，仍为狄道县，属金城郡”。
②《嘉庆重修一统志》卷252?兰州府?狄道：“晋初因之，惠帝时为狄道郡治，张骏改县曰降狄道，为武始郡治，寻复曰狄道。后魏属武始郡。”（《四部丛刊续编》，商务印书馆，1934 年，2314 册）",
