Spatial Characteristics And Structure Optimization Of Nanjing Leisure Tourism Based On Network Data Mining

With the advent of the leisure time, leisure tourism as a new format of the tourism industry development is undoubtedly becoming one of today's large-scale and strong momentum of development of the industry, and the rapid development of the industry projected to the physical space is reflected in the rapid growth of leisure travel space .The development status quo of leisure travel space influenced by this growth in the city, suburbs and rural areas become an important scientific proposition need to be solved urgently. From the perspective of leisure travel providers, with the data of Nanjing leisure tourism resources obtained by the navigation network data platform ,this paper detailed analyzes the characteristics of leisure tourism space in Nanjing using the nearest neighbor index, kernel density estimation and Ripley's L function and other spatial point pattern, and then put forward the corresponding structural optimization countermeasures against the existing problems of leisure tourism space in Nanjing. The paper promotes the cross integration of large data and tourism disciplines, leisure science and urban planning, deepens the comprehension of the overall leisure tourism space of the city, and enriches the theoretical connotation and method system of tourism geography and leisure tourism research.Based on the mining of leisure tourism spatial data, taking the multi-scale feature analysis of spatial agglomeration, distribution location and location selection as the core, and spatial structure optimization as a development, this paper explores the general characteristics and structural optimization strategy of leisure tourism space in Nanjing. The paper mainly includes three parts: the first part (the first chapter and the second chapter), which is the basic theoretical part of the thesis. This part mainly elaborates the background and the significance of the research, defines the related concepts, research objects and research scope, introduces the research methods and research framework, combs the relevant research progress at home and abroad, and reviews. The second part (Chapter 3, Chapter 4 and Chapter 5) is the empirical research and the core of the whole text. Firstly, it introduces the data collection and processing, including the acquisition method and the process of the data, the call of the application, the selection , cleaning and sorting of the data attributes, and the establishment of the attribute database. Secondly, it analyzes the spatial characteristics of leisure tourism in Nanjing from three aspects: the clustering characteristics of leisure tourism space, the location characteristics of distribution and the multi-scale features of location selection. Finally, Based on the analysis of leisure tourism space in Nanjing, the corresponding optimization strategy is proposed. The third part(Chapter 6) is the conclusion and discussion of the paper. It expounds the main conclusions of this paper, refines the main innovation, points out the shortcomings of the paper, and puts forward the research prospect.The main conclusions of this study are as follows: (1) The leisure tourism spatial is principally distributed in the main urban area, scattered in the surrounding urban area; the recreational recreation space agglomeration degree is the highest, and the natural recreation space agglomeration degree is relatively low due to the resource attributes. Dining and shopping leisure is still an important part of recreational recreation, public recreation space supply is insufficient; about cultural and leisure space, humanities comprehensive class has a high degree of agglomeration, historical heritage class more is concentrated in urban areas but the distribution is relatively loose; compared to the geographical landscape and biological leisure space ,the natural comprehensive recreational space agglomeration degree is higher due to the constraints of the landscape conditions are weak; industrial leisure format is relatively mature, and has high degree of spatial agglomeration. Other special leisure such as pension, self-driving camp is still on starting Stage, and the spatial tends to be randomly distributed. (2) The space characteristics of Nanjing leisure tourism space is"one heart multi-point" large gathering, small scattered. It belongs to the typical core-edge diffusion spatial distribution pattern. The spatial distribution pattern of the recreational recreation is the most similar to the whole due to the number of resources dominant, but the low level agglomeration space has not yet formed. The spatial characteristics of cultural leisure space was "large gathering, large dispersion" , it generates a discrete local culture and leisure space outside the center of the gathering area-- in the Drum Tower Park and Confucius Temple area. Natural recreation space shows obvious banded and dot distribution phenomenon, and it is It is "small gathering, large dispersion" of the spatial distribution characteristics. Taking Big palace as the center, Special leisure space show a obvious center - external level expansion trend, and it is mainly dotted in Jiangning and Gaochun territory. ?Dining and leisure space forms the dual-core structure that takes Xinjiekou business district and Dongshan block as the core , sub-level dining and leisure space is often located in the center of the street area. Shopping space mainly locates three high-value gathering areas that take Xinjiekou, Confucius Temple and Hunan Road as the center,the other regional distribution is not obvious. Health care and convalescent space concentrates on the central area of Nanjing, and it mainly shows planar and dotted distribution, meanwhile, the sub-city and the streets did not form a clear spatial agglomeration. The sports fitness space shows the distribution pattern of circle structure taking Big palace as the center, and it is divided into two groups: the Drum Tower and the Longjiang River, which form the secondary center. Entertainment leisure apace and health care space is more similar, but the accumulation of space is relatively scattered. For public recreation space, planar agglomeration is predominant,while dot distribution is complementary. The cultural leisure space composed of three kinds of resources, such as humanistic synthesis, historical heritage and cultural venues, is mainly distributed in the main urban area. The three types of space are obviously concentrated in the small area. The natural recreation space is distributed along the mountain and the water, and the natural comprehensive leisure space shows the characteristics of small gathering scattered distribution. As the main part of the special leisure space, industrial leisure space forms the overall pattern with Xinjiekou as the core gathered area and other regional scatter distribution. (4) The spatial distribution of leisure travel space increases with the increase of spatial scale, and the degree of agglomeration increases first and then decreases, and the characteristic space scale is 9.86km. All kinds of leisure tourism space show obvious scale dependency. The spatial scale of location selection of natural recreation leisure space is the largest, while for the cultural leisure and special leisure space is relatively small.The special scale of location selection of dining leisure is the largest, about 10km,while the highest degree of aggregation of other recreational recreation space is in the special scale of 5km.The feature scale of cultural and leisure space involve cultural integration, cultural venues and historical heritage is also within 5km, and the three types of space are highly overlapping. The clustering scale of the natural integrated leisure travel space is not stable, and the concentration scale of the industrial leisure space is 4.25km, and the range of location choice of this kind of resource is the lowest.(5) In Nanjing, there are many issues about the leisure tourism space , for example,the space development need to be guided, the spatial overlap phenomenon is serious,the function of the core area is too single,the leisure tourism function has not yet been formed,the lack of spatial integration is insufficient,the regional core attraction needs to be improved, Tourism resources integration, the top design to be perfect. And then based on the analysis of these issues, the paper puts forward optimization strategy for current spatial structure, including the construction of urban leisure tourism development and control mechanism, the differentiated guidance of leisure tourism industry development, the promotion of the tourism functions of the core area, and the strengthen the group development function.
