The aim of system design is to do the meteorological emergency services work to enhance public weather service capabilities. Based on the satellite communications technology and 3G communication technology,combined with the resources of the provincial mete-orological bureau mobile weather emergency vehicles and other equipment,design a set of platform system software based on GIS under narrowband data environment to meet the mobile weather emergency service,the software contains GIS emergency services topics and me-teorology graphics demonstrating topical part. With the help of WEB,mobile weather emergency on-site service is well done,and through e-government network,the system provides the weather emergency service for the relevant government departments. The practical results show that the system can satisfy the actual requirements of meteorology emergency service.% 系统设计的主要目的是为了做好气象应急服务工作，提升公共气象服务能力。系统以卫星通信技术和3G通信技术为基础，结合省气象局移动气象应急车辆等装备资源，基于GIS技术设计开发了一套在窄带数据环境下，满足移动气象应急现场服务的平台系统软件，软件主要包含了GIS应急服务专题和气象图形图像展示专题两部分；通过WEB方式，较好地实现移动气象应急现场服务，并可通过电子政务外网，给政府相关部门提供气象应急服务产品数据展示。实践结果表明系统满足气象应急服务工作的实际需求。
