Research On The Spatial Analysis And Protection Strategy Of The Linqing Chaoguan Site Area From The Perspective Of Genetics

The Grand Canal was a major water transportation route during the feudal society of China.The Grand Canal promoted economic development and cultural exchanges by integrating the resource elements of various regions,driving the development of towns along the canal.The establishment of the Chaoguan,a tax institution,is not only an important part of the national tax policy,but also promotes the rapid development of related cities.Linqing is one of the important ones.Chaoguan is the core of Linqing Chaoguan historic district.It retains a large number of cultural relics and dwellings of different periods,and has rich historical and cultural connotations.By using phylogenetics methods,this paper studies the Linqing Chaoguan historic district,sorts out the evolution of the district,explores the factors that affect the development of the district and their mechanism,so as to completely understand the district,and then deeply explore the characteristics of the district and propose targeted Protection strategy.This paper is divided into five chapters:The first chapter of the thesis is the introduction.Through reviewing the background and the related theories of historical district,finding that the current historical district have such problems as a single protection model and attention to currentization.The characteristics of the blocks can be further explored by means of genetics.The second chapter of the thesis is to discuss the application between the space of historical district and the research methods of phylogenetics.Firstly,it analyzes the spatial influencing factors of historical district,and divides them into two categories: natural factors and socio-cultural factors.Combining related cases to illustrate the specific impact of different influencing factors on the block space.Secondly,it explains the specific operation methods and research characteristics of phylogenetics,and discusses the significance of phylogenetics methods for the study of historical district.Finally,establish a spatial research model of historical district from the perspective of phylogenetics,that is,through two steps of "spatial reduction" and "spatial overlap",treat historical district as a dynamic development system,always taking the status quote as the research focus,Retrospective research methods and forward-looking narrative methods restore historical truth,find the main factors that affect the development of the block,and analyze the specific role of each main factor in each stage of block evolution;and use this as a basis for "spatial overlap",The spatial results under the influence of various factors are superimposed todetermine the heritage elements of the district,and to summarize the spatial characteristics and value of the district.The third and fourth chapters of the thesis take Linqin chaoguan historical district as an example,and use the phylogenetics method to analyze the space of historical district.The third chapter is the analysis of the spatial restoration and evolution mechanism of the Linqing Chaoguan historical district.Based on the spatial form,the development and evolution of the district will be divided into rivers ? rivers to form villages ? towns decline ? land reforms promoted the transformation of district in four main stages.the district space evolution was discussed,and the two most important factors affecting district evolution were found: Canal economic and social policies,and the specific impact of these two main factors on block space be explained.Then,through Chapter 4,the spatial evolution results under the influence of two major factors are superimposed,and the spatial characteristics of the area of the Chaoguan district are discovered,and a comprehensive evaluation of these characteristic elements is carried out.The fifth chapter of the thesis is based on the characteristics of the historic distric heritage summarized in the fourth chapter,combined with the current situation of the Chaoguan historic district and the relevant principles of heritage protection.Put forward targeted block protection strategies.
