Study On Evolution And Optimization Of Spatial Structure Of A-level Tourist Scenic Spots In Henan Province

Henan Province is located in the central part of China.Traditionally,the Central Plains is an important area connecting north,South and east,West and west.Land and water transportation is also very developed.Henan Province has abundant and high-quality tourism resources and abundant types of resources.The rapid development of Henan’s tourism industry has brought new opportunities for its economic development.The development of tourism industry plays a vital role in the development of tertiary industry.However,there are significant spatial differences in the development of tourist attractions in Henan Province.The development of tourist attractions in southeastern Henan Province is relatively late and small in scale.The development of tourist attractions in northwestern Henan Province is earlier and larger in scale,and the spatial distribution is more concentrated.On the whole,there are spatial differences in the development and evolution of scenic spots in Henan Province.Through the study of its evolution status and mechanism,to meet the needs of regional integration and development of A-level tourist attractions in Henan Province.Based on the data of grade A tourist attractions in Henan Province in 2007,2012 and 2017,this paper applies mathematical statistics methods such as scale analysis,dominance analysis,Gini coefficient,gravity center model,nearest neighbor index,nuclear density intensity and Arc GIS visualization technology to analyze the overall,dominant,5A and natural scenic spots in Henan Province.The superiority,scale,balance,agglomeration and spatial focus of cultural and social scenic spots are analyzed.Through ArcGIS core density analysis and image display to study the spatial distribution characteristics and evolution of the above scenic spots in Henan Province,the following conclusions are drawn: Macroscopically,the distribution of A-level tourist attractions in Henan Province has been highly balanced in the past ten years,and this situation has been strengthened.Henan’s tourist attractions are in a state of agglomeration.Microscopically,in the past ten years,the areas with higher agglomeration degree of A-level tourist attractions mainly concentrated in the surrounding areas of cities and the areas with superior tourism resources,and mostly showed the spatial distribution characteristics of dot-like to strip-like;their spatial distribution characteristics showed a state of development from dot-like to strip-like,mostly along traffic routes or mountain ranges;the areas with general agglomeration degree of tourist attractions mainly presented strip-like and area-like.By comparing with the above analysis results,this paper explores the impact of natural factors,scenic spot types,socio-economic level and tourism traffic conditions on the spatial distribution of A-level tourist attractions in Henan Province.Finally,suggestions are put forward from three aspects: spatial optimization principle,optimization path and optimization measures.
