摘要
以图们江流域为研究对象,结合文献资料、卫星影像和地形图,调查具有洪水泛滥危险的地形,根据其洪泛危险程度将洪泛危险地形划分为3个等级,并制作了洪泛危险地形图.在此基础上,建立了河流汇合型、Avulsion型和曲流泛滥型3种洪泛危险地形模型,为预测和预防洪水灾害提供了科学依据.
Flood hazard in the Tureen River is classified into three stages of the flood risk based on the characteristics of fluvial landforms. Various Kinds of Flood hazards were mapped by the GIS data analyze skill. Besides, Flood hazard were classified based on geomorphic condition： confluence inundation flood, avulsion flood, and meander band flood.
