摘 要：
时间序列分析是研究灌区退水量演化规律的重要方法。采用时序图和自相关图相结合的方法,以宁夏青铜峡灌区为实例,对大型灌区的日退水量时间序列进行了分析,确定了大型灌区日退水量时间序列的非平稳特性和1阶2步差分平稳性,为灌区退水量的准确预报提供了理论依据。

摘 要：
Time series analysis is an important method to study the evolution of irrigation return water.Timing diagram and self-correlation diagram approach were used,taken Ningxia Qingtongxia Irrigation areas as an example,which determined the time series of return water had non-stationary and first-order two-step difference stationarity features,which provided a theoretical basis for an accurate prediction of return water.
