渭河流域水文变异诊断研究
The research on the hydrological variation diagnosis of the Weihe River basin
摘要
Abstract
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.关键词
