吐蕃时期的信息传播媒介

由于藏的创制和成熟，吐蕃的信息传播发生了历史性转变，进入了人类传播的第二个阶段——字传播时代。吐蕃的字传播以竹木、纸、铜钟、石头等为栽体，出现了初步的繁荣。与此同时，一种新的“信息发布机制”——盟誓也盛行于世。驿道逐渐成为信息传播的主要栽体。吐蕃逐渐形成了自己独立的传播品性。

Writing system communication took bamboo, wood, paper, bronze bell and stone as vehicles towards preliminary prosperity. Meanwhile, a new information spreading system, i.e. pledging, had come to prevalence. With post road gradually became the main vehicle for information transmitting; Tubo finally established its independent transmitting quality.
