In China， ice and snow tourism is becoming the core driver of ice and snow economy. China can powerfully realize green transformation and upgrading development by means of developing ice and snow tourism. The concept of ice and snow tourism is discussed firstly in this text. After that， the authors elaborate that the formation process of “ice and snow +” all-for-one tourism development mode on the basis of analyzing the historical development of China’s ice and snow tourism. This paper analyzes the endogenous-external development mechanism of “ice and snow +” all-for-one tourism development mode according to the all-for-one tourism development thinking. A set of “ice and snow +” all-for-one tourism development mode systems are constructed based on the analyses of their regional differences. The system is composed of snow and ice industry development mode in Northeast China， ice and snow sports events mode in pan Beijing-Tianjin-Hebei region， ice and snow-silk road culture development model in Shaanxi， Gansu， Ningxia， Xinjiang Uygur Autonomous Region and western part of Inner Mongolia Autonomous Region， self-driving exploration and sightseeing model over the Qinghai-Xizang （Tibet） Plateau， glacier sightseeing resort model in big Shangri-la region， ice and snow leisure experience development model in southern China. Although the Beijing Winter Olympics and national all-for-one tourism policy have promoted Chinese snow and ice tourism to achieve the “quantity” jump and fusion development， but it is suffered from climate warming， market competition， and ice and snow technology development. In the end， the article suggests to establish planning and decision-making mechanism involved from governments， enterprises， and individuals， to balance use of ice and snow resources， to moderate exploitation of glacier tourism resources， to develop ice-snow culture resources and scientific and technological resources， to take comprehensive development path， to enhance anti-risk resilience of snow and ice tourism.
