Surface　irrigation　is　the　most　widely　used　cropland　irrigation　method　in　the　world.　In　the　arid　and　semi-arid　regions　of　our　country,　the　border　irrigation　and　furrow　irrigation　of　surface　irrigation　techniques　are　used　widely.　The　major　factors　which　influence　the　effect　of　surface　irrigation　are　found　by　quantizing　observation　in　the　different　periods　of　the　entire　surface　irrigation,　which　provide　the　scientific　evidence　for　improving　the　water　quality　of　surface　irrigation.　It　is　a　trend　that　surface　irrigation　system　is　evaluated　and　designed　properly　by　making　a　numerical　simulation　toward　the　process　of　surface　irrigation.　It　is　the　SRFR　software,　which　is　created　by　the　Arid　Agriculture　Research　Centre　of　American　Agriculture　Department,　that　is　used　the　most　widely　and　representatively　in　the　present　surface　irrigation　simulation　software.　This　article　mainly　focused　on　the　application　of　the　WinSRFR　software　in　surface　irrigation　evaluation　and　design　system,　which　is　on　the　basis　of　introducing　the　relevant　factors　and　its　field　test　briefly　in　the　surface　irrigation　evaluation　and　design.　©　2011　IEEE.
