Fuzzy Matter Element Model for Evaluating Environmental Carrying Capacity of Ground Water

Groundwater is important for people to live, environmental carrying capacity of groundwater is more important for industry and agriculture and people and the earth to exist and develop. On basis of the matter element theory, the fuzzy-matter element model based on informational entropy (FM-IE) is built by combining informational entropy and fuzzy theory and matter element & extension set; it is used to evaluate environmental carrying capacity of ground water. A sample is explained to validate it is feasible and reasonable. 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 element model based on information entropy is clear and compact, 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.
