利用分数布朗运动及R/S分析理论，将相关函数与 Hurst系数结合在一起，从整体上识别与判定渭河流域的水文变异及其变异程度。诊断结果表明：泾河流域降雨与径流序列变异不明显，变异程度为无变异，渭河中上游及整个渭河流域的降雨序列均为弱变异，渭河流域径流序列为中变异，渭河中上游径流序列变异最为明显，为强变异。

Based on the fractional Brownian motion and R/S analysis theory,some related func-tions combined with Hurst coefficients are employed to recognize and determine the hydrological variations and their variation degrees on the whole in the weihe river basin.The results of the di-agnosis suggest that:the variation of precipitation and runoff series in the Jinghe basin is not ob-vious,and the degree of the variation is no variation,the variation of precipitation series in the middle and upper reaches of the Weihe River basin and the whole Weihe River basin is weak alter-ation,the variation of the runoff series in the Weihe River basin is moderate alteration,the varia-tion of runoff in the middle and upper reaches of the Weihe River basin is the most obvious, strong alteration.
