旅游建构城市群"乡土-生态"空间的理论框架及研究展望

"Ruralism-ecology" space of urban agglomeration (RESUA) is an important part of land space and an organic part of urban agglomeration space. It is also a strategic space for urban agglomeration to optimize the spatial structure of urban and rural areas, maintain traditional human activities, inherit regional history and culture and maintain a healthy ecosystem. It is of great significance to focus on the process, pattern and mechanism of RESUA constructed by tourism so as to meet the national strategic needs and the disciplinary construction of tourism geography. This paper systematically sorts out the relevant literatures on urban agglomeration space, tourism development impact and essential attribute of RESUA. We find that there are some deficiencies in existing research. First, the existing research focuses less attention on the marginal zone in and around urban agglomeration. Therefore, it is necessary to explore and define the new functional geographical space. Second, the existing research focuses less attention on the fact that tourism significantly affects China's economic and social space as well. Thus, it is requisite to reinforce the typical spatiality study of China's modern economic system construction, ecological civilization construction and excellent traditional cultural inheritance and innovation promoted by tourism. Third, the existing research focuses less attention on the utilization method of RESUA. So it is essential to enhance research on urban-rural space utilization and urban-rural relationship evolution. This paper suggests that tourism, as a new industrial path and new utilization method, scientifically guides the implementation of the main function-oriented zoning, and promotes the transformation and upgrading of RESUA. Therefore, exerting the influence of tourism in the spatial structure optimization of urban agglomeration and the sustainable development of urban agglomeration is a major measure to explore the path with Chinese characteristics of national land renovation and space optimization. On the basis of establishing the "three-stage" theory hypothesis of RESUA constructed by tourism, the future research can be conducted in the following aspects. First, it is required for researchers to follow the research route of "process-pattern-mechanism-effect" and explore the practical path of RESUA constructed by tourism. Second, researchers should propose a technological path to study the policy security system of RESUA constructed by tourism. Third, the general characteristics and laws of RESUA constructed by tourism should be explored in different scales.
