摘要: 地表水和地下水的转换及其过程耦合模拟，是水资源开发利用和科学评价的基础，为了准确模拟区域地下水动态变化，需要将地表水与地下水进行耦合计算。根据SWAT分布式模型的特点，以其水文响应单元(HRU)和MODFLOW模型的有限差分网格(CELL)作为基本交换单元，将SWAT模型计算的地下水补给量和潜水蒸发量引入MODFLOW模型的地下水补给(RCH)模块和潜水蒸发(EVT)模块中，并将其应用于西安市黑河流域的地下水模拟计算。基于GPR技术，对模拟结果进行检验。结果表明，SWAT模型与MODFLOW模型的耦合计算，能准确模拟和预测该地区的地下水资源及其地表水和地下水之间的相互作用。
Abstract: In recent years, water resources are increasingly affecting the global environment and economy. Conversion process and its coupling simulation of surface water and groundwater are the founda-tion of water resources development and utilization, and scientific evaluation. In order to simulate change in regional groundwater, the quasi-distributed watershed model, SWAT was coupled with the fully-distributed groundwater model MODFLOW in simulation. The hydrologic response units (HRU) in the SWAT model were exchanged with cells in the MODFLOW model. By using the HRU- CELL conversion interface, the distributed groundwater recharge rate and the groundwater eva-potranspiration calculated by SWAT were introduced into the RCH and EVT modules of MODFLOW. The application of groundwater simulation in the Xi’an Heihe River basin of Shaanxi Province demonstrated that the coupled SWAT-MODFLOW was capable of predicting the groundwater situ-ation, and of being used for investigating the interaction between surface water and groundwater.
