基于GMS的靖边县古山坑地下水源利用量研究

陕西榆林近年经济增速名列全省前列，但水资源匮乏严重制约着经济再上新台阶，选择黄土高原腹地的靖边县榆林炼油厂古山坑水源地作为研究对象，采用GMS技术，准确模拟集中开采下的地下水三维流形态，研究在工业生产规模扩大、地下水需求量增加的条件下，整个研究区地下水位的变化情况。研究表明在补给主要靠自然降水的干旱区，进行长时间、大流量取水，地下水位会持续下降，水资源呈负均衡状态，选择合理开采方案可降低风险，实现可持续发展。

Study on Groundwater Availability in Gushankeng

Although the economic development of Yulin ranked top in these years, shortage of water resource has been the limit to economic growth. Based on GMS technology, the paper builds a 3D flow model of groundwater which has been heavily exploited to study water-level variation when industry expands and demand of groundwater increase. The result shows that constant water in-taking will decrease water-level of groundwater, especially for which located in the arid region, and even make water resource in a negative balance. Therefore, the government should choose rational exploration scheme to reduce risk and finally realize sustainable development.
