摘　　要：浙江省杭州市寿昌江流域属于典型的湿润地区,流域内部多遭受台风、梅雨等强降水影响,流域内大量存在的小水库群改变了原有的坡面汇流模式。以寿昌江流域为例,基于可视化建模的需求,结合地理信息系统理论及工具,将传统的新安江产、汇流模型、小水库群的调蓄,以及流域洪水预报、实时校正等模块集成为整体,形成流域防洪预报系统,提高流域洪水预报精度,为此类典型区域的洪水预报提供方法借鉴和系统支持。The Shouchangjiang Basin,located in the Hangzhou city Zhejiang province,is a typical humid area.This basin has been frequented by typhoon,Meiyu and other heavy precipitation.There are many small reservoirs scattered in the basin,therefore,the natural rainfall-runoff process has been altered.Taking Shouchangjiang Basin as an example,based on the demand of visual modeling,combined with the GIS theory and tools,the traditional Xin'anjiang model,the regulation and storage of small reservoir group,as well as the modules of basin flood prediction and real-time correction are integrated into a whole to form a basin flood prevention prediction system,which improve the accuracy of basin flood prediction.It also provides methods for flood prediction of similar areas.
