摘要：Due to the significance of the region water security, ten indexes are selected as evaluation indexes for regional water security from society, economy and ecology respectively. After using the law of entropy to calculating the indexes weights, variable fuzzy sets is presented to calculate the rank feature value of water security system. Finally the model is used to evaluate the water security of some city. The method can fully use one's experience and knowledge, qualitative and quantitative information of index system to obtain weights of indexes for operating comprehensive evaluation for water security, and it can effectively evaluate the status of water security. The numerical example has shown that the proposed method is feasible and effective, and the evaluation results are reasonable.
