| With the advance of new-style urbanization and urban agglomeration become regional economic development pattern of our country's most dynamic geographical unit.New-style urbanization strategy of urban agglomeration as the space subject,the rational and orderly development of its internal structure,not only to support and lead regional economic and social development,but also to promote the optimization of national land space development patterns.Urban agglomeration tourism in the urban agglomeration building process has a unique advantage,helps to promote the optimization and adjustment of the internal structure of urban agglomeration,promote the integration of urban agglomeration.Tourist flow as the tourism development key elements of the urban agglomeration directly related to the integrative construction of urban agglomeration tourism,affecting the integration of urban agglomeration in the development process and direction.The logic thought in this study follows the mainline of "question consciousness-theoretical foundation-empirical research-research summary",while "current situation-process-mechanism" as the research thought of part of empirical research.Urban agglomeration as a special geographic unit for research range,to urban agglomeration in the middle reaches of the Yangtze River for cases,based on on internet platform of tourism "big data" mining,using social network theory,and grounded theory,and fractal theory,and GIS space analysis method,theory and method for urban agglomeration tourist flow spatial pattern and evolution process research,reveals urban agglomeration tourist flow law,and proposes on urban agglomeration tourism development and the integration of revelation.Enriches the research of tourism geography in part on the content,expanding the tourist flow,urban agglomeration research perspective,has the important theoretical value and practical significance.The paper is divided into seven chapters:The first chapter is the introduction.On the basis of research background and putting forward the problems,this study teases research literature of tourist flow and urban agglomeration tourism,grasp the domestic and foreign research dynamic and trends,and puts forward the goal,content,method and technical route of this study.In addition,the basic situation of the case,data sources and processing are introduced.The second chapter is to define relevant concept and confirm theoretical basis.Relevant concepts such as urban agglomeration,tourist flow and network structure of tourist flow are first defined,then related theoretical basis such as the theory of tourism spatial structure,social network theory,spatial interaction theory are described.The third chapter is to analyse current situation of spatial pattern of tourist flow in urban agglomeration in the middle reaches of the Yangtze River.The overall spatial pattern and the spatial pattern in special time of the case,the spatial pattern of tourist flow of the inner urban agglomerations and the spatial pattern of tourist flow of the center city are fully analysed.The forth chapter is to research revolution characteristics of spatial pattern of tourist flow in urban agglomeration in the middle reaches of the Yangtze River.The evolution characteristics of geographical distribution,the relationship between the flow direction and network structure are respectively analysed to summarize the evolution characteristics of spatial pattern of tourist flow.The fifth chapter is to research revolution mode of spatial pattern of tourist flow in urban agglomeration in the middle reaches of the Yangtze River.To distinguish the spatial mode of tourist flow in urban agglomeration,the basic types of spatial evolution mode of urban tourist flow are put forward,the characteristic of tourist flow in different spatial mode are discussed,and spatial revolutional mode and benefits of tourist flow in urban agglomeration in the middle reaches of the Yangtze River are deeply analyzed.The sixth chapter is to research infuential mechanism of spatial pattern evolution of tourist flow in urban agglomeration in the middle reaches of the Yangtze River.Influential factors of spatial pattern of tourist flow are reduced and refined,the interaction and mechanism between influential factors are explored,then infuential mechanism and process from the main influential factors to the evolution of spatial pattern of tourist flow in urban agglomeration in the middle reaches of the Yangtze River are analyzed.The seventh chapter is the conclusion and prospective.The main conclusion and innovation points of this research are induced,the rule of tourist flow in urban agglomeration and revelation for the tourism development and the integration of urban agglomeration are refined,the deficiency and prospective of this study are pointed out.The main conclusion of this study are followed:(1)Travel "big data" mining through the internet platform,research for the tourist flow spatial pattern,affecting factors and mechanism at different temporal and spatial scales.(2)Urban agglomeration in the middle reaches of the Yangtze River tourist flow is clustering spatial distribution pattern,with strong regional executive,network development is not balanced.(3)City is the important carrying space of tourist flow in urban agglomeration,the most tourist flow centralize in the inner space of 3 km range,the 3 km space range of the core attractions as center are the active zone of tourist flow of the internal city.(4)Spatial pattern of urban agglomeration tourist flow in the middle reaches of the Yangtze River gradually showing "diaspora,small clustering" distribution in the evolutional process,fractal structures become more complex,the "hub-and-spoke" spatial organization models evolved and developed,network structure development to further improve.(5)Spatial evolution model of urban agglomeration tourist flow which includes three basic types:polycentricity clustering model,extended model,hain-shaped spactial model,which to a certain extent,reflect the evolutional processes and stage characteristics of urban agglomeration tourist flow.(6)Spatial pattern influential factors of tourist flow consists of 4 dimensions and 31 basic factors,travel motivation and leisure time are the core factors of formation and development of spatial pattern of tourist flow,while traffic accessibility,popularity and destination weather climate are important influencing factors.(7)Law of tourist flow in urban agglomeration prove the general rule of tourism flow,such as distance attenuation,administrative regional law,are also subject to the spatial correlation between the central cites,refecting the personality of urban agglomeration as a special geographical unit.Key features and innovation of this research are mainly manifested in the following aspects:(1)Urban agglomeration as a special geographic unit for research range,to reveal the spatio-time evolutional law of tourist flow in urban agglomeration,to explore the generality and the personality of the law of tourist flow in urban agglomeration.(2)Grounded theory in the field of qualitative research is introduced into tourist flow research,combining quantitative research methods with qualitative research methods to research tourism flow.(3)The experience of tourists as the basis,the web text data published by tourists are deeply digged,the formation and mechanism of tourist flow are refined,which could provide a new and rich material for influential factors and mechanism of tourist flow. |
