Application of fuzzy clustering model in groundwater runoff zones classification and indicator correlation analysis

There are many factors influencing the groundwater runoff strength. The indicator size has different influence on the strength of groundwater runoff. The relation between some indicators and the strength of groundwater runoff are positive correlation, the relation between other indicators and the strength of groundwater runoff are negative correlation. The fuzzy clustering model in the theory of engineering fuzzy sets is applied to analysis the correlation between the strength of groundwater runoff and indicators in the paper. With real cases, we can discuss the application of fuzzy clustering model and test the practicability and validity of this method.
