唐代的道路系统

The Route System in Tang China

一、京师长安通往各地的交通干线唐代都于关中,以长安统帅全国各处。关中虽为四塞之地,其间道路都是畅通无阻。当时曾于交通要道险要之处,设置关隘,以限制中外。所设的关隘全国共有二十六座,分为上中下三等。京城四面关有驿道的为上关,全关有驿道及四面关无驿道的为中关,其余则为下关。京城周围的上关有六座,为京兆府(治所即在长安)的蓝田关、华州(治所在今陕西华县)的潼关、同州(治所在今陕西大荔县)的散关、陇州(治所在今陕西陇县)的大震关和原州(治所在今宁夏回族自治区固原县)的陇山关。

The vast territory of Tang China was conveniently connected by a well-developed route system,which included arterial routes between the primary capital and localities,main routes between the secondary capital and localities,and routes between prefectures and counties.Certain sections of the Tang empire’s comprehensive land-water routes constituted an important component of the Silk Road and contributed significantly to the success of the latter.
