Analysis And Optimization Of Regional Tourism Spatial Structure Of Tourism Ring Road In Western Yunnan

Under the background of the full development of global tourism and mass tourism,interregional tourism cooperation has become an inevitable trend.As a major tourism province,Yunnan Province put forward the development strategy of building a "Deqin Shangri La Lijiang Dali Baoshan Ruili Tengchong Lushui Gongshan Deqin" Tourism Ring Road in western Yunnan in April 2019.The construction of the Great Western Yunnan Tourism Ring Line strengthens the regional cooperation among the States and cities in western Yunnan and helps to establish a cross state tourism destination.Based on this,how to correctly understand the tourism spatial structure of the tourism ring line in western Yunnan has important practical significance for promoting the overall development of the region,integrating the tourism resources in western Yunnan,promoting the flow of economic information and tourists,and accelerating the overall upgrading of tourism in western Yunnan.Through the combination of qualitative research and quantitative research,this paper uses a variety of research methods such as GIS analysis,social network analysis and geographic detector to study the tourism spatial structure from four parts: tourism resources,tourism transportation,tourism flow and tourism economy,and puts forward optimization strategies and suggestions based on the research results.The main conclusions are as follows:(1)The spatial distribution of tourism resources along the western Yunnan Tourism Ring Road is mainly concentrated in the south central and north central parts of the region,showing a high degree of concentration and low equilibrium aggregation distribution pattern.(2)The area with the largest traffic network density is located in Dali city.The comprehensive accessibility ranking of node cities from high to low is Dali,Lijiang,Baoshan,Tengchong,Mangshi,Shangri La,Lushui,Ruili,Gongshan and Deqin.The traffic time of scenic spots in the ring road is mainly within 0 ～ 90 min,and the number of scenic spots in the 60 min ～ 90 min time circle is the largest,and the overall traffic conditions are poor.(3)The tourist flow in the region is in the shape of "8".The main activity areas of tourists are Dali,Lijiang and Diqing.There is less tourist flow in the north and south,and Baoshan City is the node of "8".There is a big gap in the flow of tourists in different states and cities,showing an uneven phenomenon.(4)The economic connection degree of node cities is positively correlated with the accessibility.The better the accessibility,the greater the economic connection degree.From high to low,the total tourism economic ties are Dali,Lijiang,Mangshi,Tengchong,Baoshan,Shangri La,Ruili,Lushui,Deqin and Gongshan.The centrality of economic connection of node cities is relatively balanced,and the tourism economy is connected through a small number of node cities.The agglomerated subgroups are divided into four groups.In the "core edge" structure,the economic connection between the core area and the edge area is quite different.(5)The indicators affecting the spatial distribution of scenic spots are divided into main influencing factors,secondary influencing factors and general influencing factors,among which the main influencing factors are natural landscape,cultural landscape and tertiary industry.(6)The coupling coordination degree of accessibility and tourism economy is gradually reduced from Dali and Lijiang to both ends of the region,indicating that the relevant links of tourism economy exceed the accessibility needs,and the tourism transportation of prefectures and cities other than Dali can not meet the needs of tourism economic development.According to the comprehensive research conclusion,Dali is currently the central city of the Great Yunnan West Tourism Circle.According to the relevant research results,this paper proposes optimization measures from five aspects: the spatial structure of tourism resources,the tourism transportation network,the tourism industry structure,the tourism center city,and the connection between the tourism area and the outside world.development pattern of the district.
