The Study On The Optimization Strategies Of Traditional Towns' Public Space In The Sichuan-chongqing Region On The Background Of Cultural Tourism

China has been focusing on the overall urban and rural development after the rapid urbanization. Under such background, traditional towns as the link between the city and village have very important value in studying. Nowadays most of the traditional towns in the Sichuan-Chongqing region are in tough development and have scarcely chance. This paper takes cultural tourism as an opportunity of the development of the traditional towns, considering the resources advantage of traditional towns. And then taking the public place as the research object, this paper researches the optimization strategies of traditional towns' public space in the Sichuan-Chongqing region on the background of developing cultural tourism.This paper is divided into five parts and the first is the introduction. The first part introduces the research background, defines the research object and the related concepts, points out the research purposes and meanings, explains the research methods and summarizes the domestic and foreign related theories as well as the achievements.The second part is problem research. First of all, the related concepts about the cultural tourism were defined through studying the related literature. And then introduces the current situation of the cultural tourism's development in the traditional towns with the actual cases. Secondly introduces the relationship between the cultural tourism and traditional towns, including the spatial demand of cultural tourism to the traditional towns, and the influence of the traditional towns on the cultural tourism.
