Research On Military Waterproof Engineering System And Architecture In Lianghuai Area Of Song Dynasty

In ancient China,the confrontation between North and South regimes occurred repeatedly and continuously in the long history.The eastern part of the North-South confrontation,namely the Huaihe River and Huaihe River(part of Anhui,Jiangsu and Henan and Hubei provinces today),has always been the frontier of the confrontation between the North and South military forces.Especially in the Song Dynasty,the Huaihe River and Huaihe River area were the lifeline of the Song Dynasty regime,and became the economic reserve area in the Northern Song Dynasty and the frontline defense area in the Southern Song Dynasty.Taking the military waterproof engineering system and waterproof building in Lianghuai area of Song and Huai Dynasties as the research object,this paper studies the military waterproof environment,regional waterproof,military city pool waterproof,all kinds of defense engineering construction and waterproof building in the area.Firstly,starting from the study of ancient Chinese military defense system,this paper combs the natural conditions of Lianghuai area in Song and Song Dynasties,studies its location,geographical environment and water system conditions,and analyses the historical development process and strategic position of water defense engineering system through the analysis of political,military and economic background of Lianghuai area.Secondly,starting with the water defense engineering system in the Huaihe River and Huaihe River regions,this paper systematically expounds the basic elements and characteristics of the water defense engineering system in the Song and Huaihe River regions,summarizes the unique "point,line and surface" water defense pattern in the Huaihe River and Huaihe River regions,and analyses the defense situation and strategy of the important water defense lines in the Huaihe River and Huaihe River regions.From the perspective of defensive structures or engineering technology,the regional water defense projects and tactics in the Huaihe River and Huaihe River are classified and expounded.Thirdly,from the point of view of military city pool,the water defense engineering system is investigated and studied.Starting from the overall defensesystem of military towns in the two Huaihe River Basin,this paper analyses the formation and historical evolution of military towns in the two Huaihe River Basin,the characteristics of Defense Space and defense strategies.From the point of view of city pool location,this paper puts forward the location strategy of building city by water and integrating city water.From the point of view of city pool water air defense room,according to the three spatial levels of water defense in city,water defense on city and water defense outside city,the defensive characteristics and construction projects of city pool water defense engineering system are discussed.Finally,the research on the waterproof buildings in the Song Dynasty is carried out to study their operation and function in the whole waterproof engineering system.Among them,three typical types of dams,gates and sluices are selected to analyze and summarize their origin,development,classification,shape,operation mechanism,construction materials and other aspects.At the same time,statistical analysis of their legacy is carried out.In this paper,the military geography,military city pools,waterproofing projects and waterproofing building sites of the two Huaihe war zones in the ancient Song Dynasty were investigated on the spot.Based on historical records,local chronicles and other documents and multidisciplinary materials,the military waterproofing engineering system and waterproofing buildings in the two Huaihe war zones were studied,their historical development veins were sorted out,their spatial morphological characteristics were analyzed,and their texts were summarized.It provides reference and guidance for protection and utilization.
