摘要: 坡地汇流过程是流域汇流的重要组成部分。基于设计的室内土槽降雨径流同位素实验,以线性水库汇流模型为例,利用同位素信息分割流量过程线为直接降雨和土壤水两种水源,与水文信息相结合,确定线性水库汇流模型参数。实验结果表明,利用同位素信息可以分别确定线性水库汇流参数直接降雨消退系数和土壤水消退系数,在一定程度上可以降低参数确定的不确定性。同位素流量过程线分割中误差累积对利用同位素信息确定线性水库汇流参数结果有一定影响。

Abstract: Hillslope concentration is an important component of concentration in catchment. Based on designed rainfall-runoff experiment in trough and the linear reservoir concentration model, the total discharges of trough were separated into two-component water sources: direct precipitation and soil water. The parameters of concentration model were estimated by using isotopic and hydrologic information. The experimental results showed that recession coefficients of direct precipitation and soil water in concentration model could be individually estimated by using isotopic information, and that the uncertainty of parameters were effectively reduced. The result of parameter estimation was affected by the errors of hydrograph separation.
