摘要
为探究地表水回补地下水对地下水水资源和水环境的影响,本文以北京密怀顺地区南水北调水回补地下水工程为例,利用对应分析法分析了回补后11个监测井的地下水水位和水质的变化特征.研究结果表明:1)2015-2016年间在北京潮白河密怀顺段,南水北调累计向潮白河补水4413万m^3,河道补水后入渗量为4362.2万m^3,占总调水量的94%;2)地下水水位抬升明显,近河道监测井最大升幅达到13.98 m;3)由于回补水质较好,以及包气带和含水层的过滤作用,地下水回补后地下水水质得到改善.本研究结果可为北京市密怀顺地区地表水地下水联合调度提供参考.
Environmental impact of surface-water recharging of groundwater in the South-to-North Water Diversion Project in Mihuaishun replenishment area was corresponding analyzed.Water level and quality in 11 monitoring wells in MihuaiShun replenishment area were measured after recharge.In 2015 and 2016,the South-toNorth water Diversion Project in the Mihuashun area of the Chaobai River of Beijing replenished a total of 44.13 million m^3 of water to Chaobai River,with infiltration of 43.62 million m^3,accounting for 94%of total water supply.Groundwater level rose significantly,with maximum increase of 13.98 near the river.Groundwater quality improved due to better quality of replenishing water and filtering effect of aerated zone and aquifer.This study provides some reference for joint operation of surface water and groundwater in Mihuashun district of Beijing.
