| 摘 要： | 大荔县是关中盆地的农业大区,也是陕西经济最活跃的地区之一,而水资源不足成为经济快速发展的制约因素。本文在收集资料、水文地质调查的基础上,通过对地下水采样分析测试,采用单项指标法,对大荔县地下水水质进行综合评价,找到3处地下水质安全区域;采用整理水文勘探资料、地下水流数值模拟方法对水质安全区地下水资源量、天然资源量、地下水现状开采量以及地下水开采潜力进行定量评价;结合大荔县安全饮用水缺水现状,对农村安全供水进行区划;结果表明:地下水质安全区只有黄河漫滩南部地区具有1 687×104 m3/a的开采潜力,对解决大荔县安全饮用水供需矛盾具有重要意义。

| Abstract: | Dali County is an important agricultural area in Guanzhong Basin,and is one of economically active areas in Shaanxi Province.However,water resource shortage has become a factor restricting further economical development.Based on collecting some information and surveying the hydrogeological conditions,the authors evaluated the water quality of the shallow groundwater by conducting groundwater test and using the single norm method.Three areas of safe groundwater resource were found.This paper evaluated the safe area groundwater resource quantity in Dali County by adopting the information collection and numerical simulation technique.At last,the exploitation potential of the safe area groundwater resource was computed.According to the fact of the safe groundwater resource shortage,the safe water supply in Dali County was zoned.The result indicates that the exploitation potential of the safe area groundwater resource in Dali County is up to 1687 ×104m3/a.This conclusion has important significance for solving the contradiction between the supply and the need of the safe groundwater resource. |
