Questions are raised from the aspects of spatial cognition, street hierarchy, and the regularity of urban fabric. The significant contrast of block dimensions between eastern and western cities is revealed, by comparing the layout pattern of the urban blocks of Tang Chang'an with that of Kahun of ancient Egypt, Olynthus of ancient Greece, Timgad of ancient Rome, and Mirande of the Middle Ages, as well as Old Herat of Afghanistan. It is concluded that a typical ward of Tang Chang'an had a dual structure of strict super-grid placed over residential quarters in an organic growth pattern. The socio-economic causes of this unique structure are also explored. Finally, the authors make a quantitative comparison between a ward in Tang Chang'an and Heijo-kyo of Japan respectively and illustrate the essential difference on concept and structure between the two models.展开更多
