西汉长安的近畿空间设计,是以“十五”及其衍生数据为模数,建构成具有内在尺度秩序的严整格局。其表现出的环形规划方式与山川形势的结合,也反映出秦汉时代天文观测与都城建筑尺度设计思想的紧密关联。这种设计实践可上溯至秦,并延及后世,是中国古代都城设计方法的重要参考要素。 The design of Kinki’s space in the Chang’an of the Western Han Dynasty is modeled after the “fifteen ” and its derivative data and constructed into a strict pattern with an inherent scale of order. The combination of circular planning and the mountainous situation shows the close relationship between the astronomical observation in the Qin and Han dynasties and the design of the metropolitan scale. This design practice can be traced back to the Qin, and later extended to the ancient capital of China is an important reference method of design elements.
