基于图论的旅游型传统村落公共空间结构演变研究——以三个侗族旅游型传统村落为例

Research on the Evolution of Public Space Structure of Tourism-type Traditional Villages Based on Graph Theory through Three Tourism-type Traditional Villages of Dong Ethnic Group

旅游已成为传统村落公共空间更新的主要驱动力,开展相关研究对促进传统村落可持续发展具有重要意义。文章以三个旅游型侗族传统村落为例,利用图论分析方法,对旅游介入前后的公共空间结构进行拓扑分析,从整体形态和组构关系两方面解读其演变特征,并探究其影响机制。结果表明:三个村落呈现相同公共空间结构整体形态演变特征,空间集聚效应明显,发展格局向外扩散;三个村落公共空间结构组构关系演变特征呈现一定差异性,结构层次差异化变迁,空间联系呈现"紧密-脱离"双向转化,活动类型构成呈现单一性和多元性两种特点。旅游型传统村落公共空间结构的演变过程,是旅游需求、开发强度、开发模式和开发对象社会结构共同影响的结果。

Tourism has become the main driving forces for the renewal of public space in traditional villages.It is of great significance to carry out related research to promote the sustainable development of traditional villages.With three tourismtype traditional villages of Dong as examples,this paper uses the graph theory to make topological analysis on the structure of public space before and after the tourism intervention,interprets the evolution characteristics of public space structure from overall morphology and configuration relationship,and studies its influence mechanism.The results demonstrate that the three villages show the same overall morphological evolution characteristics of public space structure which has obvious agglomeration effect and outgoing development pattern;the evolution characteristics of configuration relationship of the public space structure in the three villages are different;the hierarchy of public space structure changes in different degrees;the spatial connection of public space structure presents a two-way“close-disengagement”conversion;the activity type of public space presents two characteristics:unicity and diversity;the evolution of the public space in tourism-type traditional villages is the result of the mutual influence of tourism demand,tourism development level,tourism development mode and social structure of development objects.
