汉代洛阳古城防务问题探微

A Probe into the Defense of Luoyang Ancient City in the Han Dynasty

从西周洛邑营建到西汉末年,洛阳的防务布局由东都洛邑防务体系的重要组成部分到东周君治下重要都邑,再到秦三川郡防务体系的中枢以及内史京畿之地的东部战略屏障的组成部分,进而发展成为西汉时期河南郡防务体系的中枢以及拱卫京畿的重要组成部分。东汉时期,定都洛阳,宫城、城门守备严谨,五营可供皇帝调遣,又有“八关”可戍守,防务体系日渐完备。洛阳古城也由西周初建而逐步向北、向南扩建,既借助山川天然屏障,又修建城墙防护。

From the establishment of Luoyi in the Western Zhou Dynasty to the end of the Western Han Dynasty,the defense layout of Luoyang was an important part of the defense system of Luoyi in the Eastern Capital,to an important capital under the rule of the Eastern Zhou Dynasty,and then to the center of the defense system of Sancheon Prefecture in Qin and the eastern part of Gyeonggi.As part of the strategic barrier,it developed into the center of the defense system of Henan County during the Western Han Dynasty and an important part of the defense of Gyeonggi.During the Eastern Han Dynasty,Luoyang was the capital,the palace and city gates were strictly guarded,the five battalions could be dispatched by the emperor,and there were"eight gates"to guard,and the defense system was gradually complete.The ancient city of Luoyang was also gradually expanded to the north and south from the beginning of the Western Zhou Dynasty,with the aid of natural barriers from mountains and rivers and the construction of city walls for protection.
