降雨-径流关系非一致性演化的驱动因素诊断
Identification of primary causes of inconsistent evolution of rainfall-runoff relationship.Case study of Wei River basin
摘要
Abstract
Rainfall-runoff relationship is crucial in characterizing a watershed's capability to generate runoff.Links between rainfall and runoff have changed inconsistently as a result of the coupling effects of climate change,underlying surface change,and human activities;and the effects of these elements need to be assessed.This paper presents a method for identifying and estimating the driving factors of the rainfall-runoff inconsistency relationship,and quantifies the contribution of meteorological factors,underlying surface conditions,and human activities.This method integrates detrended cross-correlation analysis and detrended partial cross-correlation analysis.The findings demonstrate it has strong application to inconsistent series.In the Wei River basin,human activities,with an average contribution rate of 58.86%,have the greatest influence on the rainfall-runoff relationship,followed by the meteorological factors,while the underlying surface conditions have the least impact.The impact of human activities on the rainfall-runoff relationship in this basin generally takes a continuous growing trend in the time domain,while spatially its degree can be listed in a decreasing order:the upper and middle reaches of the mainstream of the Wei River basin＞the Jing River basin＞the Beiluo River basin.关键词
