西咸新区泾河新城地下水水资源评价

Water Resource Assessment on Groundwater in Jinghe New City of Shaanxi Xixian New Area

为研究陕西省西咸新区泾河新城地下水水资源特点及保证泾河新城水资源的合理开发利用,对该区内地下水天然资源量与储存量进行了计算分析。结果表明:勘查区内地下水天然条件下多年平均补给总量为2.29×105m3/d,灌溉条件下地下水的多年平均补给总量为3.36×105m3/d;开采区内地下水天然条件下多年平均补给总量为7.88×104 m3/d,灌溉条件下地下水的多年平均补给总量为1.06×105m3/d。勘查区内潜水含水岩组地下水容积储存量为3.452×109 m3,承压水含水岩组地下水弹性储存量为3.47×107m3;开采区内潜水含水岩组地下水容积储存量为1.453×109m3,承压水含水岩组地下水弹性储存量为8.24×106m3。泾河新城地下水资源量丰富,可开采潜力大,且含水层储存量较大,具有较强的调蓄能力。

To study the characteristics of groundwater resources in Jinghe New City of Shaanxi Xixian New Area and ensure the rational exploitation and utilization of water resources in Jinghe New City, the calculation and analysis were conducted on the quantity of groundwater natural resources and storage capacity in the area. The result showed that in the exploration area, under natural conditions the average annual total amount of groundwater supply was 2.29× 105m3/d, and during the irrigation period, the average amount of annual total groundwater supply was 3.36 × 105m3/d. In the mining area, under natural conditions the average annual total amount of groundwater supply was 7.88 ×104m3/d, and during the irrigation period the average annual total amount of groundwater supply was 1.06 × 105m3/d.In the exploration area, the amount of water storage capacity of the unconfined aquifer groundwater was 3.452 × 109m3 and the elastic storage capacity of the confined aquifer groundwater was 3.47 × 107m3. In the mining area, the amount of storage capacity of the unconfined aquifer groundwater was 1.453 × 109m3 and the elastic storage capacity of the confined aquifer groundwater was 8.24 × 106m3. The groundwater resources in Jinghe New City were abundant and had great potential for exploitation. In addition, the aquifer had a large capacity of water storage and a strong capacity for water regulation.
