淮河中游降雨径流相似性分析

The Resemblance Analyzing of Storm-flood in the Middle of Huaihe Valley

选取了几种降雨径流指标,运用非平权距离系数法进行相似性分析,推选出淮河流域与近年降雨径流相类似的历史年份。相似性分析得出:1983年、1968年和1996年的降雨径流与2003年具有较大的综合相似性,相反1966年、1961年和1953年与2003年的降雨径流有较大的不一致性。研究近年降雨径流与历史降雨径流的发生发展相似性,为实时的径流调度提供决策支持。

Based on several storm-flood indexes and the resemblance analyzing of uneven weight distance coefficient,some past years were selected similar to the resent years.The conclusion is:the data of storm-flood in 2003 is similar to that of in 1983,1968,1996;on the contrary,the inconsistency between the data of 2003 and that of 1996,1961 and 1953 is very evident.By studying the tendency of resemblance between the data of the resent years and the data of the past years,the tendency of real-time storm-flood will be predicted to provide the decision-making for the real-time flood control scheduling.
