利用GIS技术作为支持平台,把GIS技术应用于地下水采补平衡分析和超采区的演变上,更充分地发挥了GIS技术强大的空间分析功能。研究结果表明,典型区域自20世纪90年代以来属于超采区。到2003年浅层地下水轻微超采区占13.7%;中度超采区占57.3%;严重超采区占29%。基于GIS技术的区域地下水资源评价方法较传统的方法揭示了更多更详细的关于地下水的信息,评价结果为今后典型区域水资源综合规划和地下水调控方案的制定和决策提供了参考依据。
Using GIS technology as a support platform, the GIS technology is applied to the groundwater balance analysis and the evolution of overdraft area, giving full play to the powerful spatial analysis function of GIS technology. The results show that typical areas have been over-exploited since the 1990s. By 2003, the shallow groundwater overdraft area accounted for 13.7%; medium overdraft area accounted for 57.3%; seriously overdrawn area accounted for 29%. The traditional method of regional groundwater resources assessment based on GIS technology reveals more and more detailed information about groundwater. The evaluation results provide reference for the future formulation and decision-making of comprehensive water resources planning and groundwater regulation in typical areas.
