摘　　要：介绍了兰州铁路防洪指挥气象预警服务系统的结构设计、数据流程、系统特点、功能研究成果。该系统利用网络技术，为兰州铁路局防洪指挥提供高效、优质、及时的服务平台。系统提供实时气象资料查询72h站点精细化预报、每日3次线路预报、中期预报及沿线管界图、灾害库等资料信息。另外，统计分析了2002～2007年历年兰州铁路局水害的详细资料及气象资料后，分别给出了铁路沿线的水害时空分布特征及不同降水类型、量级影响下发生水害的特征，建立了5级预警等级，并以此为基础分别为15段铁路线路发布铁路水害预报预警信号。The structure design, data flow frame, characteristic and founction of the meteorology warning and commanding service system for Lanzhou railway flood prevention was inrtroduced in this paper. By using network technology, the system provided a highly effective, high quality and prompt service platform for the Lanzhou Railroad Bureau. The system provides the real -time meteorological data, 72 hours fine prediction, three times line prediction in a day, mid - range weather forecast and the flood disaster information as well as jurisdictional boundary chart along the route. Moreover, based on statistics of all flood disaster information provided by Lanzhou Railroad Bureau and meteorological data during the period of 2002 - 2007, the temporal and spatial distribution of flood dasster along the railway route has been obtained, and the flood disaster features under the different type and magnitude of precipitation was also obtained and five grades warning ranks have been established, the railway line flood disaster warning signal is issued for 15 routes, respectively.
