Abstract:Shallow underground water in south of Boxing county has the characteristics of wide distribution, stable reentry and alimetation condition and complicated hydrochemical characteristics. Due to unreasonable exploitation and utilization, some environmental problems occurred in this area, such as overmining funnels, salt water intrusion, soil salinization and underground pollution. Origin and evolution trend of these problems are analysed in this paper, and protection and prevention countermeasures are put forward as well.
