Abstract In order to judge the comprehensive application of irrigation district scientifically and achieve the benefit maximization, comprehensive evaluation of operational status of large-scale irrigation district is necessary. First,the Delphi and the fuzzy analysis method are combined; then the structure of entropy method is introduced based on the information entropy to evaluate the evaluation indexes;finally,the close value method is used to evaluate Luohuiqu irrigation operational status of the 2007-2012 years. The results show that the close value of the irrigation district in 2007-2012 is 2.719 2,2.205 1,1.311 7,0.485 5,0.188 8,0.000 0, respectivly, its operational condition is getting better and better. The close value of adjacent years is 0.514 2, 0.891 3, 0.826 3, 0.296 7, 0.188 8, tending to a stable condition. Comprehensive evaluation of operational status of large-scale irrigation district based on modified close value method roughly agrees with the evaluation results with the method of grey correlation theory-TOPSOS. The operational condition is getting better and better with the passage of time and more accurate, which also accords with the actual development of Luohuiqu irrigation district. This method is simple in calculation and has high reliability.
