摘　　要：以GIS栅格数据为基础,建立了二维水动力洪水动态演进模型.以湖北省荆江分洪区为实验区,在数字地形模型和LandsatETM遥感影像等数据的基础上,根据分洪区1954年分洪情况和规划运用设计,模拟了不同分洪方案下的洪水淹没范围、水深和相应的洪水淹没地物面积及其可能损失等.模拟结果表明,基于GIS栅格数据的洪水淹没风险模拟模型,可以对长江流域分洪区运用预案的制订、土地利用的规划及洪水科学管理提供定量的科学依据.A 2-D dynamic flood evolution model was established based on GIS raster data, and a case study was performed for Jingjiang flood diversion area of Hubei Province. With the help of the digital topographical map and Landsat ETM remote sensing image, the flood inundated area, water depth, flood inundated ground surface, and economic loss which might occur were calculated under different flood diversion schemes according to the flood diversion situation and its hydrological planning in 1954. The simulated results show that the flood inundation risk simulation model provides a scientific basis for formulation of diversion schemes, planning for land utilization, and scientific management of flood.
