• 摘要：本文论述了环境质量评价信息系统的模糊性和随机性。运用模糊随机可测理论度量了评价系统的不确定熵。研究了评价模型的要素,如环境质量的度量和环境质量评价标准。通过一个实例说明了模型的应用方法,本文表明即使随机的、模糊的信息也是有价值的。

• Abstract：A mathematical model of a fuzzy information system, with randomness and fuzziness, on criteria for environmental quality was studied. Using fuzzy probability measure, an information entropy of assessment was introduced. Some properties of the criteria model, such as environmental quality measurement and standards for assessment are discussed. A case study was also performed to show the application of the method.
