| 【目的】利用模糊物元模型对再生水资源的价值进行评价，为城市的经济发展、水资源的合理利用和节水型社会建设提供参考。【方法】依据全面性、科学性、系统性和可操作性原则，建立统筹经济、社会、生态环境和再生水资源价值4个方面的评价指标体系，采用专家调查法和熵权法相结合的方法确定各评价指标的权重，并采用模糊物元法计算西安、咸阳、宝鸡和渭南4个城市的再生水资源价值评价结果，最后采用模糊综合评判法及层次分析法对评价结果进行校验。【结果】利用建立的统筹经济、社会、生态环境和再生水资源价值的评价指标体系，对西安、咸阳、宝鸡和渭南4个城市再生水资源价值进行评价，得到上述4个城市的欧式贴近度分别为0.696 8，0.619 6，0.513 9，0.427 6，Ⅰ~Ⅳ等级的欧式贴近度分别为0.864 9，0.707 4，0.489 7，0.380 6，通过计算西安、咸阳、宝鸡和渭南的贴近度与4个等级贴近度的欧式距离，确定4个城市的再生水资源价值等级分别为较高、较高、较低、低。通过模糊综合评判法和层次分析法对4个城市再生水资源价值评价等级进行校验，表明评价结果合理可信。【结论】基于模糊物元模型，统筹经济、社会、生态环境和再生水资源的再生水资源价值评价体系客观合理、可信，具有一定的推广应用价值。 |

| Abstract: |
| 【Objective】Value of reclaimed water resources was evaluated to provide reference for economic development,rational use of water resources and construction of water-saving society in cities.【Method】Based on comprehensive,scientific,systematic and operative principles,the evaluation index system covering economy,society,environment and renewable water resources was established.The expert investigation method and the entropy method were combined to determine the weight of each evaluation index.The results of Xi’an,Xianyang,Baoji and Weinan were calculated with the fuzzy matter element method and verified by the fuzzy comprehensive evaluation method and analytic hierarchy process.【Result】The established evaluation index system covering economy,society,environment and renewable water resources was used to evaluate the reclaimed water resources values of Xi’an,Xianyang,Baoji and Weinan,and the euclid approach degrees were 0.696 8,0.619 6,0.513 9 and 0.427 6,and the euclid approach degrees of the gradesⅠ-Ⅳ were 0.864 9,0.707 4,0.489 7 and 0.380 6,respectively.The levels of renewable water resources of the four cities were higher,higher,lower and low,respectively.The fuzzy comprehensive evaluation method and analytic hierarchy process indicated that the assessment results were reasonable,credible,and good for further application.【Conclusion】The established system for renewable water resources value evaluation was reasonable,credible,and good for further application. |
