摘　　要：在冲积层厚度较薄、地下水埋藏较浅的山区河谷地带,边界条件对地下水可开采量和可利用能量(温度)影响较为明显。为此,以一医院水源热泵系统为例,在建立耦合数学模型的基础上,利用TOUGH2软件,模拟评价河流边界对潜水水热运移的影响过程与程度,定量研究河流边界附近潜水水量与能量的动态变化规律。为研究该条件下地下水环境变化有一定的现实意义。In mountain valleys, where accretions are thin and groundwater is shallow, variation of river boundary ＇ s condition has an great influence on the available amount of exploration and available energy （ temperature）. The paper, therefore, taking a water source heat pump system in a hospital as example, makes quantitative research on variation law of shallow groundwater quantity and energy along river boundaries by building a coupling mathematical model and discussing the influence process and level of reiver boundary＇ s changes on shallow geothermal water migration with use of TOUGH2 software. The study has practical value for further research on environment changes of groundwater in this region.
