Abstract:: The total area of Yellow River-irrigated area is 64.23×10⁴ hm² with the salinity area is 39.72% and gravity irrigation area 48.92%.In the past 20 years,soil salinization is the development trend of the overall stability and the local increase.The main reasons are as follows: few building and conservation of channels,degradation of both equipments,the new arable land cultivated increased,urbanization and industrialization building occupied by non-salinization of arable land increased.The result is that local scientific crop rotation disturbed and Yellow high gravity irrigation area of dipping is against the irrigation district because of the poor management science.The corresponding control measures are to strengthen the channels and build retaining the collapsed ditches,speed up the cultivation of new land fertile ground for the building of salt in water-saving irrigation management,build anti-erosion ditches between the highly pump-irrigated areas and low spontaneously-irrigated areas under the premise of raising the irrigation level.
