The backwardness of rural agriculture, environmental destruction and pollution problems in China have aroused more and more attention from people all over this country. While many countries in this world use tourism as an important strategy to improve the environment and rural development, this article analyzed the practice of rural tourism in China and other countries, and found out lacking of policy support is one of the reasons for the stagnation of rural tourism development in China. Therefore, the author proposed a framework of rural tourism policy, including the reform of land policy, resource and environment policy, food security policy, rural tourism industry and financial policy, training policy, and rural tourism business policy, hoping that an improved policy system can guarantee and guide the rural tourism developing sustainably in China.
