Study On Spatial Differentiation And Its Evolution Of Regional Tourism In Bohai Ring

Tourism spatial differentiation was that differences between regions of tourismdevelopment and that spatial distribution and influence，the basis of tourism spatial structure、spatial influence and all about tourism phenomenon and factor space research. This paperused many quantitative methods, combined with SPSS, ARCGIS etc advanced softwaretechnology to study tourism spatial differentiation evolution in Bohai Ring. After analyzingdevelopment of regional tourism economy, resources conditions and progress of regionaltourism cooperation in recent years, studied tourism spatial differentiation evolution in bohaiRing from the global and local two aspects.Global research study concluded:bohai Ring regional tourism center of gravity wholeslant about10°east southeast direction transferred107.88km; the regional tourism center ofgravity and geometric center of gravity were different degree of migration，overall regionaltourism center of gravity had to be a regional geometry close focus trend；Jing jin ji plate wasthe core region of the tourism development，but the core status reduced2008years later;absolute difference of bohai Ring tourism development showed an enlarging trend, relativedifference was narrow; skewness coefficient showed a fluctuation decline situation, the citiesthat below the average level reduced gradually, regional tourism development presented abetter situation.Local research study concluded:most urban tourism specialized level improved,development speed of that cities were faster than regional average, status of the lessdeveloped tourism cities once highlighted; tourism structure of urban agglomeration in bohaiRing tended to "flat look normal pyramid" type, parts of the city had cross-realm trend from alower to a higher level; in the spatial structure, diffusion effected than gathering on the whole,the original development axis would keep extending outward, new axis unceasinglyhighlighted, a large-scale tourism region gradually constructed and improved. In short, spatialpattern of bohai Ring tourism development was becoming more reasonable. Finally, this paper discussed preliminarily spatial differentiation evolution mechanism,evolution forces included tourism resources and product development、economic developmentpromoting、industrial upgrading driving、agglomeration diffusion、resource constraints、planning and policy adjustment cet. Tourism resources and tourism product development werethe dominant position of influence, foundation impetus; regional economic development、resident income level were internal driving force；policy control and the tourism plan wereexternal power; natural resources and the tourism resources is a significant external spaceconstraint mechanism.
