摘　　要：利用信息论的基本概念 ,构造了分析水文序列信息差异度的诊断方法 ,并用于长江上游某控制站的年最高洪水位序列和陆水流域年降雨序列的时间变异性分析。结果表明 ,此法可有效地诊断水文序列的变异性 ,所得结论符合实际 ,具有较高的理论价值。结合中长期水文气象预报 ,研究和分析区域水文生态序列的时间和空间变异性特征 ,以便了解气候和生物圈状况的区域变化对水文。Based on information theory,diagnostic method used for analyzing the information difference of hydrological series is presented,which is also used to analyze the yearly highest flood stage series at a control station on the upper reaches of the Yangtze River and the time variability of the yearly rainfall series in the Lushui River Valley,The result shows that the variability of hydrological series can be diagnozed effectively with the method.The result fits in with practice and is of great value.Characteristics of time and space variability of regional hydrological and ecological series are studied so that the effect of the regional change of climate and biosphere on hydrology,ecology and water resources can be found out.
