摘要
淮河中游地区洪涝灾害频繁。选取淮河中游北岸典型区作为研究区,以统计分析为研究手段,在半定量半定性分析的基础上,利用1951-2010年的研究区降水、淮河干流流量和水位数据进行了内涝与外洪的遭遇分析,以确定研究区由于淮河干流水位高于支流水位造成的"关门淹"现象的严重程度。分析认为,历年来较为严重的6个洪水"关门淹"的年份按危害程度由小到大排列依次为:1956,1968,2007,1991,2003和1954年。上述排序将为蓄滞洪区防洪除涝潜力分析在选择典型洪水年份时提供一定的依据。
Flood and waterlogging disasters occur frequently in midstream of the Huaihe River. This paper analyzed the severity of closed floods and the encounter of the inner and outer flood in the study area. The analytical method adopted is statistical analysis based on the combination of semi - quantitative and semi - qualitative ways. Data for analysis include precipitation of the study area and flow rate and water level of the Huaihe River in 1951 -2010. The analytical results showed that there were six serious flood years, which were arranged according to the severity of the closed flood from minor to major： 1956, 1968, 2007, 1991,2003 and 1954. The sequence will provide some reference to the selection of the typical flood years in the flood control potential analysis of the flood detention areas.
