杜甫《投简成华两县诸子》诗题、系年辨正——以唐代赤县制度为中心

On the Title and Writing Year of “To Scholars of Cheng and Hua Counties”:with National County System of the Tang Dynasty as the Center

杜甫有诗《投简成华两县诸子》,诗题中究竟是"成华",还是"咸华",存在着争议,进而对"两县"所指、创作时间,也演绎出诸多说法。本文在梳理该诗相关分歧的基础上,通过考辨,认为本诗题目仍当作《投简成华两县诸子》,"两县"指的是成都府附郭之成都、华阳两县。并推测本诗应为在乾元三年(760)初,杜公新来成都,向成华两县诸子寻求接济所作。

Whether it is Chenghua or Xianhua in Du＇s poem ＂To Scholars of Cheng and Hua Counties＂is still in discussion. Moreover,there is no agreement that what those two counties are and when the writing year is. Looking into various opinions,this paper holds that the title of that poem should be ＂To Scholars of Cheng and Hua Counties＂in which two counties are Chengdu and Huayang subsidiary to shindufu. This poem should be written in the third year of Qianyuan Period of the Tang Dynasty（ i. e.,early 760 A. D.）,when Du first arrived in Chengdu,asking local scholars for help.
