Restricted by the different management levels of scenic spots, it is difficult to obtain data on the environmental carrying capacity of tourist destinations one by one. When the traffic carrying value is 0.25-0.45, the weight of core elements is low. Therefore, from the perspective of tourist utility, we propose a method for mining the factors affecting the environmental carrying capacity of green ecological tourism. From the perspective of tourist utility, the tourism demand and tourism supply of green eco-tourism areas in a relatively ideal state is maintained through a combination of quantitative and qualitative methods. The amount of facilities and space occupied by tourists' transportation and their own vehicles within a certain period of time can be determined to obtain the characteristic data of the destination's carrying capacity. In this study, we construct a model for judging the factors of environmental carrying capacity of green ecotourism, judge and analyze the factors of environmental carrying capacity of green ecotourism, and then dig out the influencing factors of environmental carrying capacity of green ecotourism. In order to study the weight of the core elements of the proposed method when the traffic load value is 0.25-0.45, we compare it with the two original methods. The experimental results prove that the weight of the core elements of the method is always higher, which is more suitable for mining of the influencing factors of the carrying capacity of the green ecological tourism environment.
