摘要 以2018-2022年临汾市63个地下水监测站逐月监测数据分析评价临汾市地下水现状,平均站网密度达到22.6个/1000 km^(2)。2022年末临汾市平原区浅层地下水平均水位较2021年、2020年末均上升,临汾市尧都区地下水降落漏斗范围有所缩小。采用水位动态法进行超采评价,临汾市平原区约883.93 km^(2)浅层地下水年均下降速率在0~0.5 m/a,约1079.66 km^(2)浅层地下水年均下降速率在0.5~1 m/a。 There are 63 groundwater monitoring stations in Linfen City,with an average network density of 22.6 per 1000 km^(2).Based on the monthly monitoring data of these groundwater monitoring stations from 2018 to 2022,the current situation of groundwater in Linfen City was analyzed and evaluated.At the end of 2022,the average water level of shallow groundwater in the plain area of Linfen City increased compared to the end of 2021 and 2020,and the range of groundwater depression cone in Yaodu District of Linfen City was reduced.Using the water level dynamic method for overexploitation evaluation,about 883.93 km^(2)of shallow groundwater in the plain area of Linfen City has an average annual decline rate of 0~0.5 m/a,and about 1079.66 km^(2)of shallow groundwater has an average annual decline rate of 0.5~1m/a.
