Research On Post Transmission System Along The Great Wall Of Ji Zhen,Chang Zhen,Xufu Zhen And Zhenbao Zhen In Ming Dynasty

As the World Heritage and China’s large-scale cultural heritage,the Great Wall is a strict hierarchical,integral and systematic military defense system,but the huge system of "neural network"-the post transmission system,its authenticity and integrity has not been fully recognized,which affects the overall research and value cognition research of Ming Great Wall,as well as the progress of heritage preservation and utilization.Based on the overall system view and the perspective of spatial analysis,and the historical data mining and field investigation,and relying on the GPS positioning and GIS spatial analysis technology,this project carried out research on the post transmission system of Ji Town,Chang Town,Xuanfu Town and Zhenbao Town of the Great Wall in Ming dynasty.First of all,through the historical data mining and field inspection combing the three levels of the post transmission system-courier station,delivery station and the emergency delivery shop,as the post transmission system including wide range and rich historical information,I use the GIS platform to build a space database of the post transmission system,integrating the historical map,aerial film,historical data and other data integrated together,using GIS space information technology to restore the transportation network of the post transmission system,achieving the space positioning,visualization and restoration of the post transmission system research.Secondly,this paper uses GIS spatial database,combining its spatial analysis technology to explore the distribution of courier station,delivery station and express delivery shops and the spatial characteristics of their transportation network distribution,as well as the relationship between the two with the natural environment and social environment.Finally,from macroscopic to microcosmic,researching and exploring the post transmission system.In macro level,the post transmission system is an important part of military defense system,combining with the existing military settlements of the database,we can carry out the four Zhen’s integrity research,exploring the internal mechanism of coordination operation,In micro level,courier station,delivery station and Jidipu can be explored and summarized.On the academic level,this paper explores the restoration research of the post transmission system of Ji Town,Chang Town,Xuanfu Town and Zhenbao Town in the Ming dynasty,improves the overall military defense system of the four towns,provides the possibility for the overall research of the Ming dynasty Great Wall,and helps deepen the whole society’s understanding of the integrity and authenticity of the Great Wall On the application level,this paper first fills the gap in the research on the overall restoration of the post-transmission system of the Great Wall in the Ming dynasty,which is conducive to the promotion of the overall recognition of the Great Wall heritage in the Ming dynasty,as well as the protection and utilization of the heritage Secondly,as a transportation system,the post transmission system has influenced the formation of roads and settlements in modern towns.Studying the transportation network in the post transmission system is helpful to analyze the current urban transportation layout and future development direction.
