GMS在水源地地下水资源评价中的应用

Application of GMS for Groundwater Resources Evaluation of A Certain Water Source

为了研究昌黎县某地下水源地开采对生态环境的影响,利用GMS建立数值模型对该水源地进行评价。依据不同的开采方案运用该模型对地下水流场进行预测,预测结果表明,该水源地设计开采量为3万m^3/d时,地下水流场能够达到稳定状态,不会对生态环境造成明显影响。

In order to study the effect of groundwater source mining on the ecological environment in Changli County, this article established a groundwater numerical model by GMS to evaluate the water source area. The model was used to simulate and forecast the groundwater flow according to the different mining schemes designed. The forecast results show that when the designed mining quantity of water source area was 30 000 m3/ d, the groundwater flow field can reach a steady state, and which will not bring obvious influence on the ecological environment.
