中文摘要：卡莱拉含水层是墨西哥萨拉特拉斯州卡莱拉含水区灌溉、工业以及饮用水的主要来源。其中，农业灌溉用水占据了卡莱拉含水层所取地下水量的80%。由于该地区降雨量有限，农业用水效低下，加之工业和城市用水量需求的迅速增长，地下水的消耗达到了不可持续的速度。本项研究的主要目的是利用MODFLOW-2000建立一个适用于卡莱拉含水区的地下水模拟模型，并对该地区水资源进行评价。本文将模型计算所得的地下水位结果与1954年到2004年间地下水位实测资料进行了对比，统计结果表明，在卡莱拉含水区中部的模型对地下水位的拟合效果较好。然而，在卡莱拉含水区的其他部分，为了提高本模型的预测精度，还应对概念模型做进一步的改进。

Abstract：Calera Aquifer is the main source of water for irrigated agriculture, industrial and drinking water purposes in the Calera Aquifer Region (CAR) in the State of Zacatecas, Mexico. Irrigated agriculture accounts for 80% of total groundwater extracted from the Calera Aquifer. Limited rainfall and low agricultural water use efficiency in combination with fast growing industrial and urban water demand are contributing to groundwater depletion at an unsustainable rate. The main objective of this study was to develop and evaluate a groundwater modeling system using MODFLOW-2000 for the CAR. Predicted groundwater levels were compared with measured data collected from observation wells between 1954 and 2004. Performance statistics indicated that the model performed well in simulating historic groundwater levels in the central part of the CAR where irrigated agriculture is concentrated. However, further improvements in the conceptual model may be needed to improve predictions in other parts of the CAR.
