Abstract: Xinjiang has a distinctive ethnic and folk culture and rich natural resources.It has great potential for tourism development,but its eco-tourism resources and industries have not been fully exploited and developed due to the low level of economic development and the lag of infrastructure construction.The construction of the Silk Road Economic Belt provides strong policy support and strategic opportunity for the development of eco-tourism resources in Xinjiang.This paper analyzed the advantages and disadvantages of the Silk Road Economic Belt to promote the development of eco-tourism in Xinjiang in order to explore the ways and countermeasures to promote the efficient exploitation of eco-tourism resources in Xinjiang through the establishment of the Silk Road Economic Belt.This paper established a dynamic analysis system to promote the development of eco-tourism in Xinjiang through the establishment of the Silk Road Economic Belt,analyzed the favorable factors for promoting the exploitation of eco-tourism resources in Xinjiang from the aspects of external power,internal tension and competitive-cooperative forces and mainly analyzed the dilemma of promoting the development of eco-tourism in Xinjiang.Based on the analysis,it is found that the Silk Road Economic Belt is difficult to form effective connection and link with the local traditional production and life style and the poor infrastructure of tourist area in the process of promoting the development of tourism industry in Xinjiang,thus affecting the role and effect of the Silk Road Economic Belt policy,while the lack of competitive-cooperative mechanism has more influence on the high-level cooperation of the tourist attractions along the Silk Road and the integration of tourism resources.On this basis,taking the construction of the Silk Road Economic Belt as the background,this paper proposed the ways to promote the development of eco-tourism resources in Xinjiang from strengthening the ecotourism planning,speeding up the construction of the tourism transportation infrastructure,establishing the consultation mechanism for tourism development and increasing the added value of tourism products to promote the efficient exploitation of eco-tourism resources in Xinjiang.
