摘　　要：根据2001～2010年甘肃省农业统计资料,应用AEZ模型,并结合GIS平台对甘肃省玉米生产潜力进行了分析.研究表明:甘肃省的玉米生产潜力仍处于较低水平,潜力提升空间较大.2009年甘肃省的玉米生产潜力为5 823kg/hm2,比2000年增长了24.40%;2000～2009年,在甘肃省3大玉米种植区中,河西地区的玉米生产潜力一直处于领先地位,是甘肃省玉米最优种植区;预计2015年甘肃省玉米生产潜力将达6 072.67kg/hm2,比2009年甘肃省玉米生产潜力增长4.29%.AEZ model combined with GIS platform were used to analyze the maize potential productivity in Gansu Province based on the statistical data from 2001 to 2010. The results showed that the maize po- tential productivity of Gansu Province reached to 5 823 kg/hm2 in 2009 ,which increased 24. 40 % compared with that in 2000. The maize potential productivity in Hexi region has been in a leading position, Hexi re- gion is the optimal planting area of maize in Gansu Province from 2000 to 2009. It is expected that the maize potential productivity in Gansu Province would reach to 6 072.67 kg/hm2 in 2015,it would increase 4. 29 compared to that in 2009. At present, the maize potential productivity in Gansu Province is still at a low level,but the potential promotion space is great.
