Abstract
From water-saving irrigation technology implementation and operation of all the major influencing factors,we established a sound water-saving irrigation technology comprehensive evaluation index system to project fuzzy set theory and entropy-information theory as the guide,built a system mathematical model of fuzzy comprehensive evaluation,water-saving irrigation for different ways to conduct an objective quantitative assessment,correct evaluation of the comprehensive benefits of water-saving irrigation,and optimized the choice of suitable water-saving irrigation pattern of the Tarim Basin.By comprehensive evaluation of different irrigation methods such as irrigation,irrigation pipe gate,horizontal border,in the current economic and technological conditions,the level of border irrigation is the most appropriate way of surface irrigation in the Tarim Basin.
