摘　　要：以北疆阿勒泰地区138hm2示范地为例,对不同控制面积自动化滴灌系统的投入与运行费用进行统计测算比较。结果表明,自动化单滴灌系统控制面积应适中,系统过大则能耗高,运行费用随之增加,田间灌水均匀度和系统安全性降低;而系统过小则会增加一次性投资,但是运行费用较低,管理也方便灵活。综合考虑,建议北疆地区自动化单滴灌系统控制面积在50-60hm2之间较为经济合理。In this paper,the author,taking the 138 hm2 demonstration land in Altay district of north Xinjiang as an example,added up,calculated,and compared investment and operating costs of automatic drip irrigation system under different control areas.The results indicate that the control area of automatic drip irrigation system should be moderate.The energy consumption and operating costs will increase once the system scale is too large,meanwhile the field irrigation uniformity and system safety will decrease.While if the system scale is too small,the initial investment will increase,then the operating costs is relatively low,and management is also convenient and flexible.Taking into comprehensive consideration,the author suggests that the economic and reasonable control area of automatic drip irrigation system is 50-60 hm2 in north Xinjiang.
