基于气象部门提供的淮河流域20个站点1955-2012年的逐日降水资料，利用线性趋势分析和 M-K 突变检验，分析淮河流域逐年、各季的降水量变化趋势和突变状况。表明淮河流域总体降雨量呈现下降趋势，各季节降雨趋势各不相同，其中在夏季降雨最多，冬季最少。在近58年发生了14次“旱涝急转”现象，并且降雨量分别在20世纪60年代和21世纪初发生了突变。

Based on the daily rainfall data from the meteorological departments of Huaihe river basin 20 sites from 1955 to 2012 ,the change trend of yearly and seasonal precipitation and mutation status are analyzed by using the linear trend method and Mann-kendall testing .It shows that the total rainfall in the Huaihe river region is declining and the rainfall trend of each season is not identical .The maximum rainfall is in the summer and the winter minimum .14 times of sudden turn of drought and flood had happened at recent 58 years ,and there were abrupt changes of rainfall in the 1960s and early 21st century .
