Research on the evolution of urban defense in song dynasty based on shouchenglu 守城录(Record of urban defense)

Abstract

ABSTRACT Shouchenglu is the first monograph on urban defense in ancient China. Based on Shouchenglu, combined with relevant historical documents and image data, this paper sorts out its content, and chooses to explore the internal logic of the evolution of urban defense in the Song Dynasty from three new perspectives: urban defense structure, city walls and their ancillary facilities, and coping strategies for siege weapons. We have carried out graphic translation of the miscellaneous contents of it, and through drawing analysis charts, we can more intuitively show the evolution of the urban defense system in the Song Dynasty and put forward analysis and conjecture. Through the study of Shouchenglu, we found that the evolution of the urban defense system in the Song Dynasty had a clear evolutionary logic. The evolution of the urban defense system in the Song Dynasty was not only the progress of architectural technology, but also the improvement of adaptability in the face of various complex situations. We believe that our research results have certain reference significance for the future urban excavation and the protection and restoration of historical heritage in the Song Dynasty.
