Abstract
Based on fuzzy-matter-element analysis, combining the concept of Euclidean distance, the fuzzy-matter-element analysis method on the base of Euclidean distance is proposed. In the comprehensive evaluation on water resources sustainable utilization, the developing stages of every region are regarded as matter elements; and compound fuzzy-matter-element is constructed with the evaluation indexes and corresponding fuzzy value. Through calculating Euclidean distance from the standard fuzzy-matter-element and adopting analytic hierarchy process method to calculate the weight of evaluation indexes, it is realized to comprehensively evaluate and sequence the sustainable water resources utilization of the regions. This model is applied to the comprehensive evaluation on sustainable water resources utilization in semiarid drought-resistant irrigated area of Gan Nan experimental region in the northeast of China, which has made good effects, being quite instructive to the sustainable utilization of Gan Nan water resources.
