摘　　要：[目的]分析干旱区绿洲玉米水分生产率的影响因素。[方法]以黑河中游张掖市临泽县的绿洲灌区为例,根据绿洲灌区主要农作物玉米生长发育期的实际情况,选取了9个影响因素进行灰色关联分析。[结果]灰色关联度大小排序结果显示,1995～2009年影响玉米水分生产率的前5位主要因素依次是化肥施用量>劳动力投入>生产用种子>地膜使用量>农药施用量。说明干旱区绿洲玉米水分生产率受可控因素的影响明显大于不可控因素。[结论]在水资源限制的前提下,未来合理高效配置农业生产中可控因素的投入,应是干旱区绿洲玉米水分生产率提高的主要对策。[Objective] The aim was to research influential factors of water productivity of maize in oasis in arid areas.[Method] In middle reach of Hei River in Linze County of Zhangye City,maize,the major crop in irrigated area in the oasis,was studied and nine influential factors were chosen through grey relation analysis.[Result] According to grey relation analysis,top five factors influencing water productivity of maize during 1995-2009 were as follows： applied quantity of chemical fertilizerslabour inputseedsmulch amount pesticide amount,which indicated that controllable factors,instead of uncontrollable ones,dominate in influence of water productivity of maize in oasis in arid areas.[Conclusion] With water resource limited,investment of controllable factors in high-efficient agricultural production should be the major strategy to improve water productivity of maize in oasis of arid areas.
