The　purpose　of　this　study　was　to　discuss　the　change　in　groundwater　level　and　quantity　supplemented　to　Mihuaishun　area　from　South　to　North　Water　Division　Project.　In　this　study,　the　method　of　numerical　simulation　was　adopted　to　predict　and　analysis　of　the　trend　of　groundwater　level　in　the　study　area　within　20　years.　The　survey　concluded　that　the　cumulative　loss　of　groundwater　resources　in　Mihuaishun　area　in　2007　∼　2016　reaches　-1.784　×　109　m3.　According　to　the　forecast,　after　the　water　source　of　South-to-North　Water　Division　continues　to　recharge　the　aquifers　at　the　rate　of　0.12　billion　m3/a　for　ten　years,　the　local　groundwater　equilibrium　changes　from　negative　to　positive,　and　the　water　level　in　the　central　funnel　area　increases　by　25m.　In　addition,　the　artificial　recharge　of　multiple　water　sources　is　also　related　to　local　hydrology　geological　conditions.　The　impacts　of　the　obtained　results　are　analyzing　comprehensively　the　influence　of　South　to　North　Water　Division　supplement　on　groundwater　and　providing　reference　for　underground　regulation　and　unified　regulation　of　water　resources　after　the　water　source　of　South-to-North　Water　Division　transferred　into　Beijing.　©　2019　International　Information　and　Engineering　Technology　Association.　All　rights　reserved.
