摘　　要：针对畦田灌水质量进行敏感性分析。应用已有的畦灌各影响因素的空间变化范围,采用均匀设计方法设计模拟方案,利用Win SRFR模型模拟得到各方案的灌水效率、灌水均匀度、储水效率和综合指标等灌水质量结果。在此基础上,利用灰色关联分析方法分析畦田灌水质量对各因素的敏感程度。结果表明,灌水质量综合指标对各因素的敏感程度从大到小排序为:改水成数G、单宽流量q、田面糙率n、畦长L、入渗系数K、入渗指数α、畦田纵坡Z。由此可见,灌水质量对技术要素的敏感性要高于自然要素,因此在进行灌溉设计和管理时,更应注重灌水技术要素的控制精度。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 indexα,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.
