中文摘要:
      南水北调京石段项目目前处在通水的初级阶段,缺乏长期的降雨实测资料,为了解渠道内的一般降雨特性,本文将石家庄市降雨资料用到南水北调京石段工程的分析研究中,利用石家庄市1951-2013年的年降雨实测资料,采用Mann-Kendall检验方法、快速傅里叶变换法、最大熵谱分析法、小波周期法对项目区63年降雨变化进行趋势性、突变性及周期性分析。结果表明:南水北调中线京石段年降雨及汛期降雨均呈现出不显著下降的趋势;年降雨序列存在两个不显著突变点:1964、2007年;南水北调京石段1951-2013年降雨周期为:4~5 a,9~11 a。
英文摘要:
      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.
