Artificial　recharge　is　an　effective　way　to　alleviate　water　shortages　and　excessive　groundwater　exploitation.　In　this　study,　to　explore　environmental　changes　of　surface　water　and　groundwater　during　multi-water-sources　recharge　process,　numerical　simulation　method　was　applied.　Local　reclaimed　water,　treated　by　wetland,　and　water　from　the　South-to-North　Water　Transfer　Project　(SNWTP)　were　used　to　recharge　groundwater　reservoir　in　Mi-Huai-Shun　District　(Miyun　District,　Huairou　District　and　Shunyi　District).　The　Flow　Model　results　showed　that　the　accumulated　loss　of　the　groundwater　resource　in　the　Mi-Huai-Shun　area　from　2007　to　2016　reached　-　1.784　x　10(9)　m(3).　All　the　water　sources　contribute　to　the　recharge　of　groundwater,　raising　the　groundwater　level　and　increasing　the　groundwater　reserves.　Meanwhile,　the　Solute　Transport　Model　results　show　that　different　water　source　has　different　effects　on　the　local　groundwater　environment.　chloride　concentration　of　reclaimed　water　source　and　wetland　water　source　are　higher　than　groundwater,　and　the　artificial　recharge　caused　the　chloride　concentration　of　groundwater　in　receiving　area　to　rise.　The　water　from　the　SNWTP　played　an　important　role　on　reducing　chloride　concentration　due　to　dilution.　In　addition,　Multi-Water-Source　artificial　recharge　is　also　related　to　the　local　hydrogeological　conditions.　This　study　provides　a　comprehensive　analysis　of　the　impact　of　multi-water-source　recharge　on　groundwater　quantity　and　quality.
