摘要：

卫星通信可以有效地实现大区域预警信息的发布，但要提高预警信息发布的针对性和准确性，必须采用有效的信息编码方法。本文首先介绍了预警信息编码的内容，然后针对卫星通信的特点，分析了各信息元素的编码问题，尤其是影响范围的编码问题，最后基于我国现有的机构代码、行政区划代码和应急管理领域的最新成果，提出了一套适用于卫星DAB的预警信息编码方法，并在实际系统中获得了应用。实际使用结果表明，本文的编码方法是一套行之有效的卫星通信预警信息发布编码方法。

Abstract:

Satellite communication is efficient for wide area alert information distribution. But for appropriate and accurate warning，it is necessary to encode the alert information elements. This paper first introduces the basic contents of alert information，then analyses the coding mechanisms of each information element，especially the influenced area，based on the transmission characters of satellite communication. In the end，this paper gives out an alert encoding mechanism for DAB satellite alert distribution according to the current achievements of geographic code，institution code and emergency management policies of China. Practical use indicates that this coding mechanism is ideal for satellite based alter distribution.

Key words: satellite communication, alert information distribution, information encoding, geographic code, regionalism code
