Beijing-Shijiazhuang section of sorth to north water transfer project is at the initial stage through water.Because of lack of long-term rainfall measured data,in order to understand the general rainfall characteristics in canal, this article used Shijiazhuang rainfall data to study the project of Jingshi section of north water transfer project.By use of annual rainfall measured data of Shijiazhuang in 1951 and 2013, the paper took Mann Kendall test method,fast Fourier transform method, the maximum entropy spectrum analysis method and wavelet cycle method to analyze the trend,periodicity and mutation of rainfall change for 63 years.The result indicated that in the middle route of the south to north water transfer project, the annual rainfall and flood season rainfall have presented no significant downward trend;there are two no significant mutations of 1964 and 2007 in annual rainfall series;the rainfall cycle of south to north water transfer project from 2013 to 1951 is 9 to 11 and 4 to 5 years.
