Abstract
Water is not only the resource of life but also the important resource for a nation survival and development. Nowadays, the water crisis has become one of the most essential factors to restrict urban development. In this case, taking reasonable and effective method for comprehensive evaluation of urban water conservation level is helpful for promoting the construction of water-saving city. The main contribution of this paper is providing a new evaluation method for urban water saving. First, an urban water-saving evaluation index system is built. And the index system takes six water-saving standards including comprehensive water saving, domestic water saving, ecological water saving, industrial water saving, agricultural water saving and social economy as criteria. Then, the water-saving assessment model is proposed based on the Multi-grade Uncertain Comprehensive Evaluation (MUCE) Method. In this method, the important degree and the corresponding remark of each evaluation index are both considered to be uncertain variables due to the human uncertainty. The weights as well as the final evaluation result are obtained according to their uncertainty distributions and the votes of experts. At last, the comprehensive evaluation for water-saving level of Handan City located in North China is studied.
