| Traffic network system have a crucial impact on regional tourism economic development,the highway network plays an important role in the traffic system and has the important influence on the tourist destination accessibility and tourist traffic flow,meanwhile the expansion of the regional tourism economic development needs requests the construction of the highway network supply.Therefore,studing the evolution mechanism of the highway network and regional tourism spatial structure is very important.The tourism industry of Guangxi zhuang autonomous region has become the pillar industry of the whole district relyed on the natural geographical environment and rich tourism resources,and towards being a strong province(area).The highway construction achieved the network pattern of connectting to the Yunnan,Guizhou,Hunan,Guangdong and other surrounding provinces and cities,sea,border after more than 20 years of development.It has a profound impact of the economic development of regional tourism in guangxi.This article is studied mainly from the two aspects: Theoretical aspect(Chapter 1,Chapter 2)Reviewing the theory of the tourism spatial structure and traffic transportation research both at home and abroad based on the selected topic background and practical value.Combing related concepts of tourism spatial structure and highway.Summarizing the growth pole theory,the theory of "core-edge","point axis" theory,etc.Empirical aspect(Chapter 3,Chapter 4,Chapter 5)Firstly,making research on the characteristic of tourism resources spatial agglomeration and the distribution of tourism scenic spot around the highway in guangxi by using the methods of gini coefficient,buffer technology etc.Summarizes the evolution characteristics of guangxi tourism spatial structure by using the first degree theory,a sequence of scale theory.Secondly,Describing the highway network accessibility evolution pattern by using the ArcGIS network analysis techniques and ESDA.Demonstrating the correlation between tourism economic development and highway accessibility evolution.Using the method of comprehensive evaluation to make an empirical analysis of comprehensive development level of the two systems,based on this,making empirical inquiry between the tourism spatial structure and highway network by using coupling,coordination degree model.Lastly,Discussing the coevolution mechanism between the highway network and the tourism spatial structure in guangxi and and proposing the collaborative optimization strategy.Conclusions are as follows:(1)Spatial pattern of tourism resources in guangxi is uneven distribution and 56.69% of the scenic spots distribution in highway 15 km buffer.The dense regions of scenic spots are in conformity with the dense regions of the highway network.(2)Tourism spatial structure evolution presents "concentration-diffusion,imbalancebalance " development trend and the relative difference of regional tourism economy level gradually decline.Summed up the "node,point axis,radiation,network" four tourism spatial structure evolution stage based on the theory of "point-axis".(3)Accessibility of highway network evolution in guangxi presented "core-edge" diffusion pattern generally and uneven state of regional accessibility receding.The evolution of the accessibility of highway network and a link between tourism economic development.(4)Highway construction and tourism development has entered into the phase of coupling.They interacted and influenced with each other and the effect degree improve gradually.However,great differences still exist between regional coordination degree.(5)Existing guidance and feedback mechanism between highway network and tourism spatial structure evolution.Through perfecting the highway network layout in guangxi,giving full play to the advantages of highway propaganda,optimizing the development pattern of tourism development and building characteristic high speed travel routes to promote guangxi highway network and development of tourism economy coordinately. |
