以2000年为基准年对临汾盆地地下水进行均衡分析,并利用GMS软件建立地下水三维数值模拟模型,计算了地下水补给量与排泄量。结果表明,2000年临汾盆地地下水补给(包括降水入渗、地表水入渗、侧向流入、河水侧渗、越流补给)量为650251.81万m3,排泄(包括蒸发、开采、排入河道、越流排泄)量为70956.67万m3,处于超采状态。提出了地下水资源可持续利用对策。
Taking 2000 as the base year, the groundwater in Linfen basin was balanced and analyzed. Three-dimensional numerical simulation model of groundwater was established by using GMS software, and the recharge and discharge of groundwater were calculated. The results show that in 2000 the groundwater recharge (including precipitation infiltration, surface water infiltration, lateral inflow, river water infiltration, over-flow recharge) in Linfen Basin was 6,025,218,100 m3, and the discharge (including evaporation, exploitation and discharge into the river course Flow excretion) amount of 709,566,700 m3, in over-mining state. Proposed countermeasures of sustainable utilization of groundwater resources.
