Abstract: Water use efficiency for farmland irrigation in North China Plain is presently only 43.1%,therefore,there exits high water saving potentiality.Through regional diagnosis and technical assessment of the suitability of water saving agriculture,the paper presents an integrated regional development order of suitable water saving technology for the years of 2010 and 2030 respectively.On the basis of the status,different agricultural irrigation technologies concerning development scale and corresponding water saving amount for these two years are calculated and analyzed.

Key words: North China Plain, suitability,water saving technologies,water saving potentiality
