苻秦皇始元年（350），置县。治今泾阳县东南二十八里。（1）后魏属咸阳郡。（2）

注：
（1）、《元和郡县志》：泾阳县“本秦舊縣。漢屬安定郡，惠帝改置池陽縣，屬左馮翊。故城在今縣西北二里，以其在池水之陽故曰池陽。後魏廢，于今縣置咸陽郡。苻秦又置涇陽縣。隋文帝罷郡，移涇陽縣于咸陽郡，屬雍州，即今縣是也。”（中华书局，
按：苻秦设置泾阳县时间无考，暂定为建国的皇始元年。
（2）、《魏书》卷106下地形志下：“咸阳郡，领县五。石安石勒置，秦孝公筑渭城，名咸阳宫。有四皓祠、安陵城、杜鄠亭、窦氏泉、周文王祠。池阳郡治。二汉属左冯翊，晋属扶风，后属。有郑白渠。灵武前汉属北地，后汉罢，晋复，真君七年分属焉。宁夷有甘泉、九嵏山。泾阳真君七年并石安，景明二年复属。”（中华书局，1974年，第2608页）。    ]]>  </source-note>  <source-uri>      </source-uri></placename>
