Ice and snow tourism: it belongs to the category of eco-tourism. As early as 1999, the eco-tourism types introduced at that time mainly included bird watching, wildlife tourism, cycling tourism, drifting tourism, desert exploration, environmental protection, natural ecological investigation, skiing tourism, mountaineering exploration, Shangri-La adventure tour, ocean tour and other ten categories of characteristic products. In the research at home and abroad, the definition of ski tourism is more common: ski tourism is a mountain holiday tourism product based on snow resources, which is participatory, interesting and exciting (Du Qingzhen, 1999). It is a field activity that returns to nature, challenges itself, strengthens physical fitness, educates and entertains, increases knowledge and cultivates temperament (Zhang Decheng, 2002). Li Yi and others (2000) think that skiing tourism is a high-level consumption activity to experience ice and snow culture in the form of skiing and meet people's material and spiritual needs, which belongs to the category of eco-tourism and forest tourism. Lv Wei Chuangjing believes that ice and snow tourism is the general name of all forms of tourism activities that take ice and snow climate tourism resources as the main tourist attraction and experience the connotation of ice and snow culture. This is a highly participatory, experiential and exciting tourism product. References:
