On the Influencing Factors of Region Eco-Tourism Spatial Structure

The supply-demand is the key research object in the market economy. Tourism cannot be realized without the supply of the tourism destination and the demand of the traveling source of tourists place. And "field" is a ubiquitous objective phenomenon that is invisible and intangible. The tourist destinations not only have the supply-demand fields but also the competition fields among destinations.Eco-tourism is the trend in today\´s world tourism development, which has made a significant contribution to global economic development. This article explores the spatial structure of the status of eco-tourism from the market relationship of supply-demand and the competitive field of physics, analyzes the relationships between supply-demand and the field, so as to realize the balance of supply-demand and the field, to indicate the direction of realizing the optimization of eco-tourism spatial structure, to seek to maximize overall efficiency and to promote the realization of the sustainable development of eco-tourism.
