Soil and water conservation not only protects the ecological environment, but also provides a unique eco-tourism destination through the establishment of various forms of model treatment engineering. On the other hand, the eco-tourism extends the conservation benefits and contributes to attract funding and social support for soil and water conservation, but it brought some pressure on the environment as well. It was discussed that how to reduce soil and water loss caused by tourism activities and establish the coordinated development mechanism of eco-tourism and soil-water conservation. Analysis of the connotation and components on the mechanism of this kind of coordinated development showed that the establishment of the coordinated development mechanism on eco-tourism and soil-water conservation should be based on establishment of driving mechanism and restriction mechanism, and clarifying the division of the interests and the responsibility of all participants. In order to gain comprehensive support for eco-tourism and soil-water conservation and achieve the maximization of comprehensive benefit, the coordinated development should start from the government support and public participation, meanwhile, respect the market rules and strengthen cooperation.
