摘　　要：利用T213数值预报产品建立包头市短期降雨预报方程,通过地理信息系统,在Citystar4.0版本软件的支持下,实现大青山区降水随高度的分布模式,计算出主要山区沟河的流域面雨量和降水总量,估计洪峰流量。在GIS(地理信息系统)环境下,研究山区面雨量的预报,通过建立包头市大青山区山体高度降雨量分布的经验公式,得到实现山区沟河流域面的面雨量,最终得到各个沟河流域的最大洪峰流量的估计。by using T213 numerical forecast products to establish Baotou city short-term rainfall forecast equa- tion, by using the geographic information system in the Citystar4.0 version, to achieve the Daqing mountain area precipitation with the height distribution pattern, calculate the main mountain river basin area rainfall and pre- cipitation, estimates of peak flow., In the GIS （ Geographic Information System ） environment, study of mountain area rainfall forecast, through the establishment of Baotou City, Mount Daqing District mountain high rainfall dis- tribution formula, get to realize a mountainous area river basin area rainfall, eventually get each river basin the largest flood peak flow estimation.

关 键 词：地理信息系统 流域面雨量 洪峰流量 数值预报
