| Traditional villages are the living products of the farming civilization of the Chinese nation.They condense the national emotion and memory inherited by Chinese children for thousands of years,and carry the excellent traditional Chinese culture,and have rich historical and cultural values.Significant regional differences in China have endowed traditional villages with distinct local characteristics.Carved over the years,each traditional village has accumulated an independent and complete cultural context,which constitutes an important part of excellent traditional Chinese culture.Public space is the important which can rich villagers daily activities,stabilize the social relations and organizational order of the village,maintain the affection of clan descendantsand and tourists conduct tourist experience activities.It is an organic structure nested in traditional village space system and destination tourism system and also one of the important topics in the field of traditional village research.However,many of the traditional villages also contributed to the following phenomena: the public space pattern of traditional villages changes,the spatial function is missing,the spaceuse of the host and the guest conflicts,and the vitality of the characteristic cultural space is lost during the process of rural tourism.If this situation sustains such a long time,it will not be conducive to the protection and inheritance of traditional village culture,and even hinder the promotion of rural revitalization strategy and beautiful village construction Therefore,it is of great significance to carry out such research on the evolution of public space characteristics of traditional villages in this study.This study focuses on the evolution of public space characteristics of traditional villages,but in fact,it reveals the evolution process of self-organization characteristics of complex system space under the intervention of tourism factors.The research takes Lian Village as an example,which is one of the Chinese history and culture villages,the first batch of Chinese Traditional Villages and National AAA Level Scenic Spots.Through site survey and on-the-spot investigation,detailed combing village of point,line,polygon shape public space elements,in the perfect system on the basis of various types of public space,using the fractal theory and the theory of space syntax to realize construction of fractal dimension model and syntax.Then,relevant software technology is used to calculate the radius dimension,box dimension,integration degree and selection degree of the point,line and polygon public space of the village under different time nodes of tourism intervention,so as to describe the evolution characteristics of the public space,and then analyze the role of tourism development in this process.Finally,based on the existing problems of villages corresponding to public space,suggestions are put forward for the optimization and improvement of Lian Village public space according to the above quantitative results and analysis conclusions,in order to promote the sustainable development of Lian Village public space system and similar traditional village tourism space system,and reflect on the shortcomings in the research process.Through the theoretical analysis and empirical research,the following findings are obtained:(1)There are few studies on tourism impact from the perspective of public space;few empirical studies treat the relationship between spatial function and form dialectically;the research on Lian Village is distributed in multi-disciplinary fields,but as far as tourism is concerned,it still stays in the qualitative description and analysis,and there are few researches on the spatial structure of Lian Village by spatial quantitative means.(2)The scale-free thought which belongs to fractal theory is fit the traditional village space research and tourism complex system research.And the space syntax theory which emphasis on space fabric can help researchers to fully recognize the traditional village internal logical relationship of the space.The advantages of the two theories can be fully demonstrated under the topics discussed in this study.(3)Through the analysis of the basic situations and tourism development situation of Lian Village,the key time nodes involved in this study are determined as 2012,2015 and 2020.The elements of the point,line and polygon public space in Lian Village are richful and diverse in subdivision types,but the number is uneven,the function gap is large and the spatial layout difference is obvious.(4)Under the influence of tourism development,the point,line and polygon public space structure of Lian village has different level fractal characteristics,the self-affine and self-organization ability of the spatial system fluctuates normally within a reasonable range.Similarly,the typical representatives of different types of public space systems also show differences due to the involvement of tourism,such as the function transfer or even disappearance of space units inside ancestral temples,the deviation of the integration center of road and view,and the change of people’s travel habits.This study can provide guidance for the optimization of Lian Village’s public space system under the background of tourism intervention.It also can provide theoretical support to the parallel or upper space plannings related Lian Village in the future.It can provide data reference for the dual goals of history culture protection and tourism development of Lian Village as well.Finally,it provides experience for protection and development of other similar traditional villages. |
