Abstract:The streets and alleys of the old city have been created and developed by the needs of people living in them. The space renewal and quality improvement of streets and alleys in contemporary old cities should be the same in the rules and logic of construction. As far as the material space of the old city of Beijing is concerned, its protection and renewal have multiple levels from the whole to the courtyard, and there are differences in the value and connotation involved in each level. Therefore, the focus of attention in the space renewal has different emphases, and the methods and even processes of the Space renewal of the old city are different. The protection and space renewal of the old city of Beijing correspond most closely to the daily life of the people at the street and courtyard levels. Based on this, the space renewal at these two levels will shift the focus from the "artifacts" in the hard environment to the "crowd" in the soft environment, that is, from the space renewal of artifacts to the needs of grass-roots residents, so as to continue the rules of the old city space in the construction of streets and courtyard. The different levels of old city space protection and renewal and the diversity of concerns and types are conducive to the formation of mutual coordination among all levels, so as to improve the rule logic and continuous control of old city space renewal.
