There are many influencing factors of irrigation quality in the border irrigation, and it is important to analysis the quality sensitivity of these factors. Based on the results of field experiments, the grey correlation analysis was combined with the WinSRFR model and uniform design to study the factor sensitivity on the irrigation quality of border irrigation. The analysis shows that the sensitivity of the factors for border irrigation can be listed according to the order from large to small as: inflow cutoff G, unit discharge q, surface roughness n, border length L, infiltration coefficient K, infiltration index α, and longitudinal slope of border field Z. The irrigation quality is more affected by the irrigation technology than the natural elements. During the design and management of border irrigation, it should be taken more attention on the controlling accuracy of irrigation technology.
