Domestic scholars are concerned about the tourism image more than ten years. However, there is little research on tourism image of the world cultural heritage. The tourism image of the world cultural heritage influence tourists＇ expectations - experience satisfaction; the recognition to the cultural heritage of the destination resident; the tourist type of the world cultural heritage Site, and the showing effect of the cultural heritage tourists. Consider the world cultural heritage tourism image connotation, it includes four parts： subject, object, body and mediator. It has the four characteristics： the main audience of the tourism image is cultural tourists, and the tourism image can be used as against marketing tool of the cultural heritage sites, and the tourism image highlight the cultural heritage of authenticity and uniqueness.展开更多
