摘要

为研究在流域或盆地尺度上降雨入渗补给地下水水文响应的滞后效应,采用ArcGIS技术,并基于MIKE SHE软件数值分析的方法,建立了丹麦Skjern流域地表水-地下水耦合的分布式水文模型,运用观测值对该模型进行参数率定。通过观测值和模拟值对比,同时分析了Skjern流域气候条件和地下水埋深对地下水水文响应的影响,结果表明:丹麦属于温带海洋性气候,Skjern流域地下水补给集中在9—12月和1—3月;地下水位埋深为1m左右时,降雨入渗补给很快到达地下水面,地下水补给峰值的滞后时间很短,大约1～2 d;对于地下水位埋深在2～5 m之间的,滞后现象较为明显,峰值滞后4～5 d;对于地下水位埋深＞10 m的, 峰值滞后时间则很长。该模型模拟Skjern流域效果较好,模型对于Skjern流域具有一定的适用性和应用潜力。

Abstract

In order to study the time-lag of groundwater recharge peaks due to rainfall infiltration, the distributed hydrological model of Skjern watershed in Denmark was established through MIKE SHE software and ArcGIS technology, and was calibrated by observed data. Through the comparison between observed data and simulated data, the influence of climate and groundwater depth on the hydrological response was also analysed. The measured data matched well with the predicted values. Results suggest that since Denmark has temperate marine climate, the groundwater recharge of Skjern catchment mainly concentrates from September to November, and January to March. When groundwater level is 1m, the peak time-lag of rainfall infiltration is short (1-2d); as the depth of groundwater increases to 2-5m, the peak time-lag of rainfall infiltration is 4-5d; whereas when the groundwater depth is more than 10m, the peak time-lag is long. This model has satisfactory result and application potential in simulating Skjern catchment.
