两汉都城规划布局探析

On the Layout of Capitals of Two Han Dynasties

两汉都城之间的布局变化表现为:宫城布局由西汉的多宫向东汉的南北两宫演变,宫城面积占城市面积的比例下降;其社稷和宗庙开始由宫城移至城南郊,但与宫城依然呈"左祖右社"的格局;灵台、明堂、辟雍等礼制建筑以及太学设置在东汉洛阳城南郊显要位置,创我国都城建设之首例;城市供水由西汉长安城的单供宫城园林用水,发展为布及整个东汉洛阳城的水资源综合利用,亦创我国都城建设之首例。

The layout of Changan site of Westem Han Dynasty and Luoyang site of Eastern Han Dynasty has obviously changes. The imperial palace layout developed from many palaces to the south and north two palaces, the ratio of area covered city area descended. The imperial divine temple and ancestral temple began to remove from in imperial palace to southern city, but the layout still retained the left ancestral and right im- perial divine. The large etiquette building like Lingtai, Mingtang, Piyong and the imperial college ect. were set up at important position southern Luoyang site, which was the first beginning of capital building in our country. The city supporting water developed from single supporting the imperial palace of Changan site of Western Han Dynasty using water to supporting the whole Luoyang city multiple using water resources, which was the first beginning of capital building in our country too.
