Groundwater　recharge　is　an　effective　method　to　solve　the　groundwater　overexploitation.　In　this　study,　the　method　of　numerical　simulation　is　used　to　discuss　the　environmental　change　of　groundwater　in　the　process　of　multi-source　recharge.　The　results　of　multiple　water　sources　including　local　regenerated　water　source,　wetland　water　source　and　South-to-North　water　source　show　that　the　cumulative　loss　of　groundwater　resources　in　Mihuaishun　area　in　2007　similar　to　2016　reaches　-1.784　x　10(9)　m(3).　The　influence　of　different　water　sources　on　the　local　groundwater　environment　is　different.　Nitrate　nitrogen　concentration　of　regenerated　water　source　and　wetland　water　source　is　higher　than　that　of　groundwater,　and　artificial　recharge　increases　the　concentration　of　groundwater　in　the　receiving　water　area.　The　nitrate　concentration　in　the　water　source　of　South-to-North　Water　Division　is　relatively　low,　which　plays　a　diluting　role　in　the　process　of　groundwater　recharge.　In　addition,　the　artificial　recharge　of　multiple　water　sources　is　also　related　to　local　hydrology　geological　conditions.　The　influence　of　multi-source　recharge　on　groundwater　quantity　and　water　quality　is　analyzed　comprehensively　in　this　study.
