摘要:
本文在关中盆地现有监测网的基础上,基于GIS技术,采用建设监测剖面与编制地下水动态类型图相结合的方法,对关中盆地地下水动态监测网进行了优化调整,形成4横5纵共9条监测剖面、239个监测点的地下水动态监测网,其中潜水监测井120个,承压水监测井119个;利用原有监测井165个,新增监测井74个。新建监测网能够较全面地控制关中盆地区域地下水动态变化,在2011年"严重缺水地区地下水监测项目"中,以动态监测数据为依据,确定了主要干旱区位置,为政府应急抗旱找水打井提供了技术支撑。
Abstract:
Based on the existing monitoring network for Guanzhong Basin, by using GIS technology, this paper combined the construction of monitoring sections and compilation of groundwater regime type maps to adjust and optimize the monitoring network in Guanzhong Basin. 9 monitoring sections (4 vertical and 5 horizontal) were constructed. This new network included 239 water holes in total (120 holes for phreatic water and 119 holes for confined water), of which 165 holes were old monitoring wells, and 74 were newly drilled. It can reveal comprehensively the groundwater dynamic changes over Guanzhong Basin. In 2011, the present network provided basic dynamic monitoring data for the " Serious water-lack area groundwater monitoring project" to determine the positions of main arid areas, which can serve for the government to look for water resource when confronted with draught.
