摘　　要：为确定安徽省淮河干流行蓄洪区不同下垫面的空间糙率分布。采用水文学和水动力学相结合方法,以1991年、2003年及2007年淮河历史洪水实测资料为基础,搭建蒙洼、城东湖、姜唐湖、荆山湖及花园湖水文水动力学MIKE模型,分析研究行蓄洪区不同下垫面的空间糙率取值,包括村庄、树丛、旱田、水田、道路及河道等,提出了适用于安徽省沿淮行蓄洪区不同下垫面糙率的取值,进行沿淮行蓄洪区的洪水风险分析。In order to define roughness coefficient of various underlying surface on Huaihe River mainstream in flood discharge and retention zones of Anhui Province, MIKE models for Mengwa, Chengdong Lake, Jiangtang Lake, Jingshan Lake and Huanyuan Lake are created combining approaches of hydrology and hydrodynamic force and based on historical observation data of Huaihe River floods in 1991, 2003 and 2007. Space roughness values of various underlying surface in flood discharge and retention zones, such as village, bushes, dry farmland, paddy field, road and river courses, have been analyzed. Roughness values of various underlying surface in flood discharge and retention zones of Anhui Province are proposed. Meanwhile flood risk analysis is carried out for flood discharge and retention zones along the Huaihe River.
