Residents satisfied with the tourist economical benefit. Both of two investigations support this conclusion that residents have common cognition manner to the traveling influence of cultural effect. They think development of the tourism can bring cultural advance. However, the residents perception on the economy is divergent. First, the residents agree that the positive effect as same as the passive effect by the traditional questionnaire; the residents environmental perception is the most vague and sensitive by using the fuzzy comprehensive evaluation. Second, residents had a different perception of the tourism bringing more pollution by the traditional questionnaire, but the reason is not found. While using the fuzzy questionnaire, tourism seasonal effect is found as the reason. On the tourism busy season, environmental pollution is serious; on the other hand, environment becomes better in off-season.
