摘　　要：在物元理论的基础上将信息熵、模糊理论和物元可拓集合有机地结合起来，提出了基于信息熵的模糊物元模型，将其应用于地下水环境承载力的评价中，为了验证该方法的可行性和合理性，做了实例验证，同时将多元统计分析中的主成分分析方法应用到地下水环境承载力的评价中，评价结果表明，两种方法取得了较好的一致性，而且信息熵的模糊物元模型理论清晰、简捷，便于计算机编程，为地下水环境承载力的评价提供了新的思路。On basis of the matter element theory, the fuzzy-matter element model based on informational entropy is built by combining informational entropy and fuzzy theory and matter element ＆ extension set; meanwhile it is used to evaluate environmental carrying capacity of ground water. A case study is explained to validate its feasiblility and rationality. Principal component analysis （PCA） method is applied to evaluate the environmental carrying capacity of ground water. It is shown that the evaluating result by two methods is same. The theory of fuzzy matter ele- ment model based on information entropy is clear and compact, and it is easy to realize by computer program. At the same time it provides a new idea for evaluating the environmental carrying capacity of ground water.
