摘要
陕西泾惠渠灌区地下水开采力度不断加大,地下水位不断下降,威胁灌区的水文生态安全。利用绘制潜水等水位线图法和ArcGIS软件,分析灌区地下水位动态。结果表明,灌区地下水位显著下降,主要原因是管理不到位,井渠使用失调。控制地下水位下降的根本途径是水资源统一管理。
Groundwater was over-exploited in Jinghui canal irrigation district,which caused groundwater table to decrease and endangered the hydro-ecology security of irrigation.Using contour map of phreatic water table and Arcgis software to analyze the change of irrigation groundwater table.The results showed that irrigation groundwater decreased obviously,mainly because of imperfect management and disorder usage of well and canal.Unified management of water resources was a fundamental way to control the drop of groundwater table.
