摘　　要：对3种节水技术模式以生产上的常规灌溉模式为对照进行了技术优属度评价,以期为山前平原主流节水技术模式的推广应用提供理论依据。以模糊集理论和嫡一信息理论为指导,构建模糊综合评价墒一权数学模型,对节水技术模式进行评价。结果表明,太行山前平原冬小麦夏、玉米节水技术模式从优到劣排序为:通用模式、简易模式、喷灌模式、传统模式(对照)。其中通用模式和简易模式两方案比较接近,较适宜在太行山前平原推广应用。The relative superiority degree evaluation of three kinds of water-saving irrigation mode are conducted by comparing with conventional irrigation mode in this paper in order to provide theory basis for the extension of main water saving irrigation mode in the Taihang Piedmont Region. The fuzzy comprehensive evaluation entropy mathematical model for water-saving irrigation system is established based on the fuzzy set theory and entropy and used to evaluate the water-saving technique mode. The result shows that the order of priority in using these water-saving irrigation modes in this region should be universal irrigation mode, simple mode,sprays irrigation mode and conventional irrigation mode. The universal irrigation mode is similar with simple mode, and both of these modes are suitable to extension and application in Taihang Piedmont Region.
