Application of fuzzy clustering method in analysis correlative of indicators of water resources system

Fuzzy clustering method (FCM) is widely used in recognition partition without evaluation criterion. Generally, FCM obtained the clustering center Matrix (CCM) by using the shortest distance from each indicator to undetermined clustering center, and divided the samples into different classes. It did not pay attention to the correlative of indicators. This paper puts forward the method that how to use FCM to analyze correlative of indicators. In order to achieve the goal as above, the fuzzy clustering iterative model (FCIM), which is proposed by Chen, is introduced in this paper. Two situations are analyzed. One is that the bigger index value the better evaluation result it will be, and the other one is opposite. This case study shows that the satisfactory result is obtained.
