This paper evaluates the irrigation efficiency in the Hetao irrigation area. Based on standardized calculations and measurements from 1985 to 1989, methods to appraise irrigation systems in arid regions have been developed. These are the mathematical statistic method of evaluating canal conveyance efficiency; the fuzzy grouping method to analyse the soil permeability of a canal bed; and the dynamic method to evaluate field water efficiency under the conditions of existing shallow ground water. Based on the results, the potential water saving in planning, operating and managing irrigation systems is pointed out and corresponding strategies in water saving are recommended.
