基于GMS的靖边县古山坑地下水源利用量研究

摘要

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。%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.
