摘要
永寿县仪井镇地区是陕西省最为严重的缺水地区之一,浅层水资源匮乏而深层岩溶水资源丰富。区内岩溶水含水介质主要由裂隙和经岩溶化作用改造后的溶蚀裂隙组成,属典型的岩溶裂隙含水介质;补给来源呈多元化特征,总体由西北向南径流,无地下水排泄点,开采甚微,均以地下径流的形式排泄出区外。根据勘探孔抽水试验资料,将区内划分为四个富水区,通过计算得知该地区天然资源量约为2 597.22×104m3/a,开发潜力巨大。
Yijing Town in Yongshou County, one of regions suffering water shortage in Shaanxi, is lack of shallow water but abundant in deep karstic water. Water - bearing media in this region mainly are cracks and grikes, which are typical water - bearing media in the studied area. Though water recharge resources are various, most of them are runoffs from northwest to south, which have no discharge point and have been explored little. According to boreholes pumping test, this study divides the studied area into four water - riched regions. The further resource calculation reveals that the total amount of natural water re- source 2 597.22 × 104 m3/a, which indicates a great exploration potential.
