Based on matter-element theory and correlation function of extension theory,mathematic models of correlation degree and matter-element for urban land suitability evaluation were established,and the suitability of five evaluation units were evaluated based on matter-element model of extension theory.

Based on variable fuzzy sets theory,the models of relative difference function and relative membership function for urban land suitability evaluation are constructed,and a variable fuzzy evaluation model for synthetic relative membership grade is presented.
