一种简单的年降雨-径流概念模型

A Simple Conceptual Model of Rainfall and Runoff

以河北省雄县新盖房水文站年径流系列分析为例建立了新盖房水文站年径流量与其控制流域的年降雨量、耗水量和水库、闸坝等蓄水措施储量关系的简单概念模型。通过新盖房水文站年径流和其控制流域年降雨的双累积曲线分析,得出不同阶段人类活动对径流的影响,从中选择具有代表现状人类活动水平的1980～1995年径流系列,对模型及其参数进行了计算和验证,以此简单的年降雨-径流概念模型计算得到了1953～1995年长系列径流量。该模型具有概念明确、简单易用、所需资料和参数少等优点。

A simple conceptual model based on the relation of runoff,rainfall,consumption and storage has been established.Through double-mass curve analysis of rainfall and runoff,the influence of artifi-cial activities on runoff was obtained.A representative runoff series from1980to1995was chosen and used to calculate the modeling parameters and calibrate the model.Using this conceptual model,a long series runoff from1953to1995was calculated.
