Analysis of Drainage Measures in Xinjiang Water-saving Irrigation Area

With drip irrigation technology in large scale,changed the irrigation and drainage pattern,which leads to the new problem of soil salinization.This paper describes the development of Xinjiang drainage measures——ditch drainage,subsurface pipe drainage and vertical drainage,and analysis of the problems of drainage measures in Xinjiang water-saving irrigation area the current and the effects of drainage on soil salt content and groundwater level.And it combines with the irrigation and drainage test in Xinjiang reservoir downstream water-saving irrigation area,put forward reasonable suggestions to the local drainage measures and provide a reference for water-saving irrigation area to reduce soil salinization.
