南宋古城防御空间特征对比研究--以静江府城和平江府城为例

A Comparative Study on the Defensive Space Characteristics of the Ancient Cities of the Southern Song Dynasty:A Case Study of Jingjiang City and Pingjiang City

城市自择址兴建始,安全防御需求贯穿发展的全过程,形成具有地域特色的防御空间。该文聚焦于南宋古城防御空间特征对比,在明晰静江府城和平江府城防御背景基础上,借助统计分析和空间句法等手段,对二者的自然、人工等物质防御空间特征进行对比。研究表明:(1)平江府城地理位置较静江府城更重要,静江府城自然环境较平江府城更利于防守,静江府城和平江府城分别呈立体式和平面式防线格局,均利用地势达到防火防洪目的;(2)静江府城的城墙、街巷防御性强于平江府城,防御性建筑分别沿主要道路和轴线布局。对古代山水城市研究、城市遗产保护和当代城市建设的引导有重要意义。

Since the city's site selection and construction,the security and defense needs run through the whole process of development,forming a defense space with regional characteristics.We focus on the comparison of the defensive spatial characteristics of the ancient cities of the Southern Song Dynasty.On the basis of clarifying the defense background of Jingjiang City and Pingjiang City,we compare the natural and artificial defensive spatial characteristics of the two by means of statistical analysis and space syntax.The research shows that:①The geographical location of Pingjiang City is more important than that of Jingjiang City,and the natural environment of Jingjiang City is more conducive to defense than that of Pingjiang City.②The defensiveness of the city walls and streets of Jingjiang City is stronger than that of Pingjiang City,and the defensive buildings are arranged along the main roads and axes respectively.It is of great significance to the study of ancient landscape cities,the protection of urban heritage and the guidance of contemporary urban construction.
