The Construction Of Urban Historical Trail System Based On Cultural Gene Inheritance

With the acceleration of urban development,the overthrow and reconstruction activities have been taking place,resulting in the replacement of the traditional style of the ancient city by the modern urban landscape.The "fragmentary" historical and cultural heritage was scattered in the city and gradually declined.In view of the dilemma of historical and cultural heritage protection and the existing problems of urban walking system,it is urgent to establish an integrated protection method of historical and cultural heritage with equal emphasis on protection and development,so as to integrate the protection of historical heritage,culture and ecology,continue the vitality of historical and cultural genes,and give play to the agglomeration effect of regional multiculturalism.By connecting the scattered historical heritage points in the city to form an overall protection network,the historical trail can not only maintain the process of urban cultural heritage,but also create a vibrant public space,which can effectively alleviate the dilemma between heritage protection and development.Due to the weak research foundation of urban historical trail system construction method,it is urgent to seek a scientific and reasonable method to guide and assist the planning and design of historical trail.This paper introduces the idea of cultural gene inheritance,analyzes the components of the urban historical trail system according to the characteristics and structure of cultural gene,and provides a more scientific approach for the in-depth exploration and expression of the internal elements of the historical trail system.From the perspective of holistic protection,this paper expounds the relationship between historical footpath and historical and cultural heritage protection,as well as the significance and function of cultural gene theory in the historical footpath system.The core content of this paper is the construction method of urban historical trail system,which is divided into four steps: identifying and grading cultural genes,constructing the suitability evaluation system for selecting historical trail lines,selecting historical trail lines and determining the layout of historical trail planning.On the basis of preliminary analysis and research,a cultural gene suitability evaluation system was established based on the historical and cultural value,scientific research and education value,artistic appreciation value and recreational attraction,and the urban sections containing cultural genes were selected.Then,from the level of cultural gene chain and cultural matrix,reasonable evaluation indexes are selected to jointly constitute the suitability evaluation system of urban historical trail selection,and the route layout of historical trail is determined through the evaluation of urban section and its constituent elements.In addition,this construction method was applied to the planning of historical footpath in the ancient urban area of changsha city.After data collection and investigation,cultural genes contained therein were extracted,and the route layout and spatial structure of historical footpath were evaluated and optimized.Finally,based on the idea of cultural gene inheritance,this paper proposes the protection and development strategy of historical trail system from three components,which can also be used for reference for other cities to build historical trail system.
