Abstract: Ethnic cultural resources transformation brings about various economic and social consequences so that we should pay attention to how to be on guard traps of cultural resources transformation. This paper constructs an early warning indicator model of traps of ethnic cultural resources from the perspectives of tourists and residents. In the model, the level of early warning is divided into five types of no warning, low warning, middle warning, heavy warning and large warning. Then we evaluate the trap of ethnic cultural resources transformation in Yunnan, Guizhou and Chongqing with the method of fuzzy comprehensive evaluation. The results show that residents wholly think that the trap of ethnic cultural resources transformation in Yunnan, Guizhou and Chongqing is at a low level, but tourists wholly think it is at a middle level.
