中文摘要: 利用淮河流域实测降水资料和水文资料,分析了2007年夏季淮河流域大洪水期间的降水时空
分布、气候统计特征以及水情特征,并与历史同期进行了比较。结果表明,2007年淮河流域
汛期强降水过程集中在6月29日至7月26日,强降水主要分为四个时段,淮河干流四次洪峰对
应着4个强降水阶段,累积降水量越大,相应的流量越大,洪峰水位也越高。2007年汛期淮
河流域平均降水量少于1954年,和2003年基本持平,但淮河中上游降水集中,降水强度大,
持续时间长,从而导致了淮河流域出现1954年以来最大的洪水。
Abstract:The major flooding event during the summer of 2007 in Huaihe River Basins is stu
died based on the observed data of precipitation and hydrology. The analysis of
the spatial temporal distribution of precipitation during the flooding period a
s well as the hydro climatology features is also carried out and compared with
historical data. As shown from the results, the heavy rainfall occurred during t
he period from 29th June to 26th July with four stages linked to four flood peak
s of Huaihe River. Higher precipitation is correlated to more flood water flow,
then leading to higher water level. The persistent and heavy rainfall in the up
per and middle Huaihe River brought about the major flood in 2007, although the
average amount of precipitation for Huaihe River Basins during the flooding peri
od of 2007 was equivalent to 2003.
