Tourism resources of the Mt. Danxia are evaluated by means of fuzzy synthetic appraisal. Based on characteristics of tourism resources of Danxia landfom

twelve evaluation factors of three groups are defined. Membership of implict numeric factors to each evaluation grade is derived from statistics of questionaire while that of explicit numeric’factors is calculated by devised membership functions. Weights of factors are classified into three grades corresponding to three groups

and each factor is distributed a different weight. Results of calculation show that the Danxia scenic spot tends to first two of the four evaluation grades. In addition

results derived from operators (。

+ )and (

V )agree well.
