Abstract：Tosolvetheproblem ofdeep groundwateroverexploitation，takingthe deepgroundwater overexploitationarea in Northwestern Shandong Provinceas theresearch area，the field deep wellrecharge test was carredoutto investigate groundwater level response to sustained recharge conditions，a finite element subsurface flow system numerical model was constructed bycombining with the hydrogeological conceptual model of the research area，and the scenario simulation of groundwaterlevelrestoration was carredoutbyseting fourkindsofrecharge schemes employingdiferentrechargemethods and volumes.The results show that the deep wellrecharge testhas acertain positive effcton the deep groundwaterlevel rise，andthedailyrechargevolumeispositivelyproportionaltothe magnitudeofthe waterlevelrise，andthegroundwater levelin the observation wels hasbeenraised by2.4mduringthe testperiodSimulations of groundwaterlevelrecovery under diffrent recharge schemes yieldvarying outcomes，withtheuseof multiple wels andhigh recharge volumes exerting the greatest influence ongroundwater flow patterns and yielding the most pronounced provincerecoveryefects.In the Northwestern Shandong Province plain region，implementing artificial groundwater recharge alongside reduced extraction can facilitate the restoration of deep groundwater levels.

随着地下水开采量的急剧增加，如何合理地开采利用水资源，减少由此引发的环境地质问题，已经成为目前地下水超采区亟待研究的重点问题[1]自20世纪70年代以来，随着社会、经济的快速发展和人口密度的增加，华北地区人均水资源量严重不足，深层地下水的开采强度越来越大[2]。（剩余11101字）
