Pozycja Measuring the perceptual quality of pedestrian public space in contemporary Chinese cities – Taking Xinjiekou area in Nanjing as an example(Lodz University of Technology Press, 2023) Mawlan Muhetar; Xia Yue; Liang Gu; Huang Chenyi; Tang LianOne of the main goals of urban design is to obtain urban space with good perceptual qualities. Among the numerous perceptual qualities, enclosure, human scale, imageability, complexity, transparency, linkage, etc. are most related to the physical features (Ewing, Handy 2009) and many scholars use quantitative methods to measure these qualities. However, when applying these methods to measure these perceptual qualities of pedestrian public space in contemporary Chinese cities, there are problems as follows: first, the existing quantitative grading standards are very diverse and they are difficult to define accurately; second, for indoor pedestrian spaces, some indicators such as enclosure, imageability, etc. need to be re-identified. This paper selects the pedestrian public space in the Xinjiekou area in the center of Nanjing as an example. Based on the existing Nolli map of pedestrian public space (Luo et al. 2021), the enclosure, imageability, complexity, transparency, etc. are measured in a relatively more objective method. Firstly, streetscape photos of typical pedestrian public space (sidewalks, public squares, interior streets, etc.) are taken to a uniform standard. Secondly, street width, building height, number of people, signs, windows, types of elements, etc. in the streetscape are extracted to match enclosure, imageability, complexity, transparency and linkage, etc. Thirdly, the obtained evaluation results are verified by graphical representation and compared with similar studies. The research finally proposes graphical representation of perceptual qualities of pedestrian public space, which will help to optimize the urban design of space.Pozycja Typo-morphology in the Urban Renewal Application – Case Study of Urban Design Project in Changting Town, China(Lodz University of Technology Press, 2023) Liu Yidan; Tang Lian; Ding WowoTypo-morphology can be seen as the research perspective and methodology of urban morphology. The terms typo-morphology are typological and morphological because they describe urban forms according to the detailed classification of building types. Typo-morphology links together a series of academic terms in urban morphological research such as type, typological process, and morphological region, emphasizing the relationship between building types and overall form in the evolution of urban morphology. To relate urban morphological research to practice, it is worthwhile to know whether these terms are still relevant in urban practice, and what their significance is. This study examines these urban morphological terms in the practical utility and value through the case of our urban renewal projects of Changting Town, a historic town in the south of China. First of all, investigation and learning of local building types are the tool to understand the way of changing by analyzing local typological processes. Secondly, clarifying morphological regions of the town based on type helps us to produce the design guides of the incremental process for renewal experienced in existing urban areas. Finally, we have found the characteristics of the tangible form of a street block based on the historical housing types, and the quantified urban form characteristics are translated into urban design control indicators. The paper concludes that the term Typo-morphology and its associated terms are meaningful in urban morphological practice which are the bridges to help the application of urban morphology turn to design control.
