传统聚落景观基因信息链的特征及其识别

"乡村振兴"和"传统文化传承"等社会经济战略给传统聚落的文化旅游发展带来了良好的机遇,同时也使得其景观特征识别、价值特征挖掘与保护等成为迫切需要解决的问题。景观基因信息链可以理解为传统聚落空间中的不同景观基因相互作用、共同构成的一种稳定的线状空间结构,文章从功能属性、形态结构、要素分布和等级地位等方面分析了景观基因信息链的分类、特征和意义。其次,结合面向对象的景观基因识别方法、地理集中指数和空间句法等方法构建了景观基因信息链的定量识别方法。最后,文章以湖南省衡山县萱洲古镇为案例进行了研究,相关分析表明:萱洲古镇的景观基因信息链在功能属性上属于典型的传统商贸型,在形态结构上属于条状型结构,过江码头巷-下河街是萱洲古镇主要的景观信息廊道,整体格局受到地形、河流、宗教思想及生活习俗等因素影响。

Features of Gene Information Chain of Traditional Village Landscape and Its Identification

Socio-economic strategies such as"Rural Revitalization"and"Traditional Cultural Heritage"have brought good opportunities for the development of cultural tourism in traditional settlements.At the same time,it has made the identification of landscape features,the mining and protection of value features an urgent problem to be solved.However,the theoretical research on the traditional settlement culture landscape genes and their information chains is still at an early stage,and has not yet been deeply studied the scientific issues such as connotation,characteristics and recognition.On this basis,this paper first clarifies the related concept from the perspective of biological genetic information chain,the cultural landscape gene chain(CLGC)can be understood as a stable linear spatial structure composed of different landscape gene interactions in the traditional settlement space.On this basis,this paper analyzes the classification,characteristics and significance of CLGC from the aspects of functional attributes,morphological structure,factor distribution and hierarchical status.Secondly,according to the object-oriented landscape genetic recognition method,geographic concentration index and spatial syntax,a recognition method for CLGC is proposed by this research.Finally,this paper takes the case of Xuanzhou Ancient Town in Hengshan County of Hunan Province as a case study.the results of the case show that:Xuanzhou’s CLGC typically character as traditional trade-cultural patterns.and Xuanzhou’s CLGC can be identified as trade-oriented landscape gene information chain.Crossing River Pier Lane-Xiahe Street is the main landscape information corridor of the ancient town of Xuanzhou.The overall pattern of Xuanzhou’s CLGC is affected by the topography,rivers,religious thoughts,living customs,etc.As a whole,this work presents a potential method for quantitative analyzing and understanding the core features of the traditional settlement landscape,and promoting the protections developments for the traditional settlements.
