Abstract:The ancient Chinese cities have different space building logic and planning design method from the Western cities, especially the idea and method of human settlement environment construction combined with landscape elements, has directed people to create a large number of“Heaven and man in one” of the chinese-style urban space. Based on the reconstruction of the historic city map of the ancient city of Qingjian County, the paper simulates and analyzes the natural landscape and river disasters by using Arcgis to explore the experience of land selection in urban construction, the paper also uses spatial syntax to analyze the evolution of urban spatial structure over the years, and summarizes the experience of its spatial structure. At the same time, Arcgis method is used to analyze the texture of urban building groups and the relationship between the sight lines of key buildings, in order to extract the experience of urban architectural layout. It is hoped that the wisdom of human settlements in ancient Chinese cities can be found and translated through scientific and quantitative analysis, so as to inspire the practice of urban planning and construction.
