杜甫陇右诗《龙门镇》再考

Another Textual Research of Du Fu's Longmen Town

诗圣旅陇纪行诗的当今地址大部分已有统一认识,唯独《龙门镇》、《积草岭》二诗尚在仁智互见之中。在前文《杜甫陇右诗〈龙门镇〉考》的基础上又进行了大量的资料查阅和实地考察,史料与实践证明:西和县石峡镇高河村的大石和小石与《水经注》记载的"龙门谷"相符,高河水为龙门水;页水为《水经注》所载的"东北穷溪",并根据《河水注》对小榆水、契水、禄谷水等表述"文法一致原则",确定页水是横水的傍流、斜支、测流,是横水的源头之一,二者不可分离;又据史料记载的一则战例和戍镇设置规模,判定今西和县石峡镇石峡街是杜甫笔下的"龙门镇",其成县府城集与西和坦途关均与史料和《水经注》所载相左。

The historical data and practical research indicate that Dashi and Xiaoshi, located in Gaohe Village, Shixia Town, Xihe County, Gansu, conform to the record in Commentary on Classics of the Rivers, andit can be drawn that Gaohe River is the Longmen River; Ye River is one of the sources of Heng River. Another record about a battle and the establishment of towns at that time show that Shixia Street in Shixia Town, Xihe County is just the Longmen Town in Du Fu＇s works.
