In a time-space compression background, the usual environment, which is the key conception in traditional tourism definition, is much difficult to be defined. Meanwhile, the tourism and recreation activities in urban background have close relations, in both aspects of demand and supply. Therefore, in empirical study as well as in policy-making, there are necessities of integration of tourism and recreation study in the urban background. The dissertation tries to construct a conceptual framework called tourism-recreation mobility based on city, on the basis of discrimination of conceptions in tourism and recreation study. Meanwhile, this study wants to offer some suggestions for Chinese cities by referring to experience of European countries. There are three problems discussed: What is the mechanism of tourism-recreation mobility? What kinds of the impacts of tourism-recreation mobility on city? What should city do? The mechanism of tourism-recreation mobility is discussed from four aspects: demand, supply, and space pattern and development trends. The dissertation concludes that the demand of tourism-recreation mobility will increase fast in China. The characters of tourism/recreation trip differ substantially from commuting, which should be the basis of tourism transportation plan. Generally speaking, Chinese cities should devote much to the optimization of tourism-recreation resources supply. The dissertation analyzes the space pattern of tourism-recreation mobility from region and city levels. The trends of tourism-recreation mobility in time-space compression background have also been studied. The development of tourism-recreation mobility has obvious impact on physical environment of cities. The development also causes intensive competition between cities in a larger area, which rises new demand for cities. To fulfill the demand of both residents and visitors, urban planning should devote to the optimization of urban functional structure, urban public space and urban transportation system. Promotion policy induced the prosperity of urban tourism in European countries. On the other hand, many cities rise regulation policy when tourism developing to a certain stage. Some common policies in European cities are essential for the general prosperity of tourism and fine quality of resident's recreation, which could be reference for urban tourism and recreation development in Chinese cities. To face the challenges raised by the development of tourism-recreation mobility, the dissertation submits several suggestions for Chinese cities, from four aspects named as tourism-recreation research, coordination of urban tourism and urban planning institutions, urban policy and urban planning formulation. Since the city is more and more shared by visitors and residents, the traditional urban planning should be adjusted, which serves mainly for the residents. Urban planning should make city more favorable for both residents and visitors, from land-use to facilities. Meanwhile, urban planning should devote to build a more attractive city
