The traditional ways of protecting heritage are often passive when facing the influence of tourism development, which makes the protection measures lag behind relatively. To solve such a problem, this paper analyzes the influence of tourism destination lifecycle and of spatial structure creatively with the theories of Tourism Geography, pointing out that the influences are different in different lifecycle phases with different distinct characteristics, that the special spatial structure always makes tourism destinations facing more complex conditions and take more heavy environment pressure. Therefore, this paper advocates taking active protection, dynamic protection, building protection system to protect the historic villages and towns.
