| 摘 要： | 采用任意多边形网格有限差分法求解模型,根据地下水水头长观资料识别模型的水文地质参数,建立了含混合井孔的6层模拟系统的地下水三维不稳定流模型来刻画渭干河流域地下水流动的基本规律.运用识别后的模型进行了地下水资源评价,预测了未来10 a不同开采条件下的地下水动态变化,探讨了地下水资源的合理开发模式,提出在以蒸发排泄为主的条件下,应在保证生态用水的前提下最大限度地夺取无效蒸发. |

| Abstract: | A three-dimensional numerical model representing groundwater flow in the multilayer aquifer system was developed to describe the basic groundwater flow rule in Weigan River Basin,Xinjiang,China. The finite difference method was used to calculate the model and identify the hydrogeologic parameters according to a long term groundwater head monitoring data.The groundwater resources were evaluated and the groundwater heads in the future 10 years under some different exploration conditions were forecast through the identified model.Then the rational model on how to utilize the groundwater resources is discussed. To capture the most of useless evaporation is appropriate to exploiting groundwater under such condition when evaporation is the main way of groundwater drainage,as long as there is enough water required by ecological development. |
