摘　　要：为了对区域水生态文明水平进行评价,针对目前水生态文明评价存在的问题,探讨水生态文明的内涵和评价方法。运用压力-状态-响应模型(press-state-response,PSR)提出由3类要素20种指标所组成的水生态文明评价指标体系;利用客观的熵权法求指标权重,减少了人为主观性对评价结果的干扰;利用物元分析方法有效解决了评价指标的模糊性和不相容性等问题,通过构造水生态文明的经典物元和节域物元,分析各个指标对应评价等级的关联度,构建了基于PSR的熵权-物元水生态文明综合评判模型。以济南市南部郊区为例进行研究,求得2010、2013、2015年水生态文明评价结果并对指标进行灵敏度分析,结果表明济南郊区水生态文明水平总体在逐渐提升,但水生态系统的压力没有明显减小,减少氨氮和化学需氧量污染物的排放是提升当地水生态文明水平的关键措施。该文模型能够揭示水生态文明现实状态和存在的问题,评价方法可供类似区域开展水生态文明评价参考。The establishment of a suitable model for evaluating water ecological civilization plays an important role in researching the relationship between the water ecosystem and human social activities.As the water ecological civilization is a vague concept,quantitative evaluation is crucial for the water ecological civilization evaluation.In order to evaluate the level of regional water ecological civilization,the connotation and evaluation methods of water ecological civilization were discussed based on pressure state response（PSR） model.Water ecological civilization evaluation index system was proposed which consisted of 3 elements and 20 indicators.Index weight was determined by the entropy method to reduce the interference of human subjectivity on the evaluation results.The matter element theory was adopted to analyze and solve the fuzziness and incompatibility of the evaluation index by constructing the classical matter element and the section matter element of the water ecological civilization.The correlation of each index and evaluation grades were analyzed.The comprehensive evaluation model of the entropy weight based on PSR was built.The model can reveal the real state of water ecological civilization and the existing problems.Combined with the model and the collected data,the water ecological civilization evaluation results of the suburbs in Jinan city in 2010,2013 and 2015 were calculated.In order to discuss the sensitivity of the index value,the sensitivity of the evaluation index to the judgement grade was analyzed.The index data of 2015 was used as the reference value.A certain value of each index was increased or decreased（respectively –5%,–10%,＋5%,＋10%） while other indicators remained unchanged.Then the grade of regional water ecological civilization evaluation was observed.The results showed the grade of the indexes including GDP water consumption,the standard rate of water functional zone and the degree of soil erosion were increasing rapidly.It meant that that this region was in conti
