With the gradual progress of urbanization, the renewal of the old city has become the focus of urbanization. This paper analyzed the street space form in the old city, and explored the characteristics of the street space form with a view to exploring streets whose space forms are suitable for the current social development. Based on the field investigation of Shijia Hutong, the White Stupa Temple area, and Dashilanr, the similarities and differences of streets in these areas with different space forms in the old city of Beijing were compared and analyzed, and social and cultural factors expressed in urban space form and the impact of human activities on the street space form were explored in terms of the scale, function, building type, and connection with the outside world. It is hoped that this paper will provide a reference for future renovation of the Old City.展开更多
