| Traditional villages have formed a unique spatial structure in the course of long-term development and evolution.Their public space structure not only reflects the specific spatial composition laws and social order,but also bears the memory of the village space and social evolution.At present,rural tourism has become a new growth point for the development of traditional villages,promoting the reconstruction of public spaces and functional transformation of traditional villages,and the development of traditional tourist villages is developing rapidly.Therefore,how to objectively recognize the update and development laws of the public space structure and explore the characteristics and mechanisms of the evolution of the public space structure of tourism-type traditional villages have become one of the urgent problems to be solved at the current stage of traditional village development.Based on this,this article takes the tourism-type traditional villages in Xiangxi area as the research object,and takes the evolution of public space structure as the core topic.First,with the help of the spatial syntactic analysis method,the topological analysis of the public space structure before and after the tourism intervention in tourism-type traditional villages in Xiangxi area is carried out,and the evolution characteristics of the public space structure of each village from the aspects of overall shape and organizational relationship is quantitatively described.Then,a horizontal comparison of different villages is conducted to explore the commonalities and differences in the evolution of the public space structure of tourism-type traditional villages in Xiangxi area.Finally,from the two aspects of external thrust and endogenous power,the influential factors and mechanisms of the evolution of the public space structure of tourism-type traditional villages in the Xiangxi area are deduced in depth,and the key points of the renovation and transformation of the public spaces of tourism-type traditional villages are proposed accordingly.The study found that: The tourism-type traditional villages in Xiangxi area show the same overall morphological evolution characteristics of public space structure,the difference between the public cores is reduced,the public space structure has obvious clustering effect,and the development pattern spreads to the periphery.The evolution characteristics of the structure relationship of the public space structure of tourism-type traditional villages inXiangxi area show certain differences,the structure of the public space changes at different levels,the spatial connection shows a two-way transformation of "tightness-departure",and the activity type composition shows two characteristics of unity and diversity.The evolution process of the public space structure of tourism-type traditional villages in Xiangxi area is the result of the joint influence of tourism demand,tourism development intensity,tourism development model and development target social structure.Tourism demand acts on the continuation and renewal of the overall shape of the public space structure.The intensity of tourism development determines the level of change in the structure of the public space.The tourism development model controls the strength of internal connections in the public space structure.The social structure of the development object affects the composition of public space structure activities.In terms of functional layout,road system and function update,the research puts forward the protection points of the public space of traditional tourist villages in western Hunan,which provides a reference for the optimization strategy and development direction of public space of tourist traditional villages in the future,which is conducive to promoting the development of rural regeneration. |
