Agricultural irrigation area is the main water user of agriculture, and its water-saving level is directly related to the realization of the whole agricultural water-saving goal. Shijin Irrigation District of Hebei Province was chosen as the study area and according to its actual situation, the fuzzy comprehensive evaluation method based on cloud model and variable fuzzy clustering iterative model was proposed to assess the level of water saving in the irrigation district from 2002-2011. This method overcame the randomness and fuzziness of the membership degree determination effectively, and made the weight determination more reasonable as well. The results showed that the water saving level of the irrigation area improved year by year, and the water saving type changed from consumption to transition. However, the whole utilization coefficients of canal-system water and irrigation water were low and needed to be further improved. The research results can provide technical support for water saving evaluation of large-scale irrigation districts and water-saving management of irrigation districts.
