隋开皇十年(590年)以海安县改名,属循州(1)。治所即今广东省潮州市潮安县(2)。开皇十一年(591年)复于义安县置潮州,县复改名为海阳(3)。

(1),《元和郡县图志》卷34?岭南道?潮州:“隋开皇十年罢郡省海阳县,仍于郡廨置义安县,以属循州。十一年,于义安县立潮州,一潮流往复,因以为名。大业三年罢州为义安郡,武德四年复为潮州。”海阳县:“郭下。本汉揭阳县地,晋于此立海阳县,属义安郡。隋开皇十年省郡,废海阳入循州,十一年置潮州,又立海阳县以属焉。”(北京,中华书局,下册,894-895页)。据此,作隋开皇十年罢义安郡时,改郡治海阳县为义安县;十一年于义安县复置义安郡时,遂复改义安县为海阳县
(2),《嘉庆一统志》卷446?潮州府?古迹?海阳故城:“在海阳县东。…《舆地纪胜》引《图经》云,州治旧在鸭湖。”(《四部丛刊续编》,商务印书馆,1934年,166册)。未见其后迁入今县记载,疑《一统志》故县在县东之说,实指清海阳县治之东,即今潮安县城区内,鸭湖也当在其内。《中国历史地图集》以县东二十五里之鸭洋当鸭湖,如此长距离迁治,《一统志》当有迁今治的下文,故不从。作古今同治处理,治所即今广东省潮安县。
