Urban density and densi fication are hotly debated topics of sustainable urban development. On the one hand, international landmark agreements such as the Sustainable Development Goals and the New Urban Agenda highlight the importance of good quality urban environments with low pollution, easy access to green spaces, walkability, and active mobility. On the other hand, densi fication can increase pollution, decrease available green spaces, and degrade walkability by concentrating vehicles and their operations. The result can be a degradation of urban liveability, de fined as a city's capacity to promote the wellbeing of residents. Yet higher urban density can also result in more effi cient urban infrastructures and networks and provide more housing (including more aff ordable housing) in more appropriate mixed-use locations. The challenge, then, is to maintain the liveable quality of this denser urban fabric. The GIS-based approach presented in this paper uses a basic liveability assessment by calculating connectivity, greenery, and urban form complexity metrics to be employed in the context of densi fication, aiming to optimize sustainability and liveability aspects. Using our study area in Salzburg, Austria, we demonstrate how such a GIS-based liveability assessment, relying on spatial data, can aid urban planners in quantifying and achieving both urban density and liveability.
城市密度和密度化是城市可持续发展的热点问题。一方面,《可持续发展目标》和《新城市议程》等具有里程碑意义的国际协议强调了低污染、易于获得绿色空间、适宜步行和积极出行的优质城市环境的重要性。另一方面,高密度化会增加污染,减少可用的绿色空间,并通过集中车辆及其操作降低步行性。其结果可能是城市宜居性的退化,宜居性被定义为城市促进居民福祉的能力。然而,更高的城市密度也可以带来更高效的城市基础设施和网络,并在更合适的混合用途地点提供更多住房(包括更多经济适用房)。因此,挑战在于保持这种密集城市结构的宜居质量。本文提出的基于gis的方法通过计算连通性、绿化和城市形态复杂性指标来进行基本的宜居性评估,旨在优化可持续性和宜居性方面。利用我们在奥地利萨尔茨堡的研究区域,我们展示了这种基于gis的宜居性评估如何依赖于空间数据,帮助城市规划者量化和实现城市密度和宜居性。

Claiming Urban Form for Liveability: An Analysis of Urban Social Movements in Istanbul 主张宜居性的城市形态:伊斯坦布尔城市社会运动分析

All dimensions of liveability, from economic to social, are directly related to urban space and its production process. However, the production of urban space, with its forms and functions, is always situated in the con flicting domain of (spatial) political economy. Conventional space production processes that favour dominant classes and produce space regarding exchange value are frequently contested with the social reaction of dominated classes defending use values and liveability. In this vein, Urban Social Movements (USMs) seem one of the key instruments for the social production of urban space with be er liveability conditions. From this perspective, the study aims to investigate USMs' space transforming capacity by focusing on the case of Istanbul. A five-step spatial analysis is conducted, assuming that USMs are closely related to the characteristics of urban development projects. In these steps (i) the location of the urban development projects and USMs; (ii) existing land use in the project areas; (iii) scale of the projects, (iv) organization level of USMs; and (v) relationships of four USM-related projects within the urban fabric are analysed. Findings of the study reveal that centrality plays a vital role in both development projects and related USMs and aff ects the programme, scale, and organization level. Considering liveability conditions, faced with aggressive capitalist behaviour supported by local and central state apparatus, USMs can realize their space transforming potential only by protecting existing programmes and urban fabric.
从经济到社会,所有宜居性的维度都与城市空间及其生产过程直接相关。然而,城市空间的生产及其形式和功能,始终处于(空间)政治经济学的冲突领域。传统的空间生产过程有利于统治阶级,并根据交换价值生产空间,这经常与统治阶级捍卫使用价值和宜居性的社会反应相冲突。在这种情况下,城市社会运动(USMs)似乎是具有更适宜居住条件的城市空间的社会生产的关键工具之一。从这个角度出发,本研究旨在以伊斯坦布尔为例,探讨USMs的空间转化能力。假设USMs与城市发展项目的特征密切相关,进行了五步空间分析。在这些步骤中(i)城市发展项目和综合管理中心的位置;(ii)重建区内的现有土地用途;(三)项目规模;(四)USMs的组织水平;(v)分析了四个与usm相关的项目在城市结构中的关系。研究结果表明,中心性在开发项目和相关USMs中都起着至关重要的作用,并影响到项目、规模和组织层面。考虑到宜居性条件,面对由地方和中央国家机器支持的侵略性资本主义行为,USMs只有通过保护现有的项目和城市结构才能实现其空间改造潜力。

East Asian urbanization is characterized by complex processes of extensive densi fication. Fuelled by rapid economic growth, Asian cities' size, scale, and physical dimensions remain incomparable to any Western se ing. During the past thirty years alone, various concepts have a empted to de fine hyperdensity, layering, and intensity as core principles of Asian urban development. Although these concepts explore the physical properties of development, few examples provide insights into the behavioural and social dimensions of such complex morphological se ings. This paper examines the eff ects of urban compaction and volumetric urbanism on liveability in East Asian cities. Hong Kong exempli fies an extreme scale and rate of densi fication. Podium developments – commercial plinths elevated above street level that connect large residential towers to commercial complexes – are one of the city's most common development types. The hypothesis is that the combination of diff erent types of podium development results in the interiorization of the urban realm, which compresses public services, social engagements, and behavioural conditions into diverse privatized and fragmented 'public interiors'. To explore these conditions, this paper first outlines the conceptual premise of reading urban se ings through the lens of volumetric urban compaction. This framework combines urban compaction and volumetric urbanism. Second, the paper discusses theories that deal with the links between spatial se ings and behavioural traits. Privatization is of particular interest here, including those processes in which the private and the public become interchangeable conditions or where the temporary occupation of functions occurs. The diff erent concepts – volumetric urban compaction and interiority – are studied within Olympian City, a podium development in Kowloon (Hong Kong). Through fi eldwork, the case is investigated in terms of the elements that make up Olympian City's spatial con figuration and how diff erent groups use space at diff erent times of the day and week. The case study shows that Hong Kong's development follows an economically driven model of volumetric urban compaction; it supports a larger privatization strategy that depends on the interiorization of the city to the extent that makes the overall structure highly exclusive, static, and controlled.
东亚城市化具有广泛密集化的复杂过程。在经济快速增长的推动下,亚洲城市的规模、规模和物理维度仍然是任何西方城市都无法比拟的。仅在过去的三十年里,各种概念就取代了精细高密度、分层和强度作为亚洲城市发展的核心原则。尽管这些概念探索了发育的物理特性,但很少有例子能深入了解这种复杂形态的行为和社会维度。本文考察了东亚城市压实和容积城市化对宜居性的影响。香港就是一个极端规模和密度化速度的例子。裙楼开发是该市最常见的开发类型之一,裙楼开发指的是将大型住宅楼与商业综合体连接起来的高于街道水平的商业基座。假设是,不同类型的裙楼开发的结合导致了城市领域的内部化,这将公共服务、社会参与和行为条件压缩为多样化的私有化和碎片化的“公共内部”。为了探索这些条件,本文首先概述了从体积城市压实的角度解读城市概念的概念前提。该框架结合了城市压实和体积城市化。其次,本文讨论了处理空间概念和行为特征之间联系的理论。私有化在这里特别令人感兴趣,包括那些私人和公共成为可互换条件或临时占用职能的过程。不同的概念——体积城市压实和内部性——在香港九龙的裙楼开发项目Olympian City内进行了研究。通过现场工作,从构成奥林匹克城市空间配置的元素以及不同群体如何在一天和一周的不同时间使用空间的角度对该案例进行了调查。案例研究表明,香港的发展遵循体积城市压实的经济驱动模式;它支持一个更大的私有化战略,该战略依赖于城市的内部化,使整个结构具有高度排他性、静态性和可控性。

Coexistence in Space: Stimulating Encounter in the Socially Fragmented Open Urban Fabrics 空间中的共存:社会碎片化开放城市结构中的刺激相遇

As one of the most problematic issues in urban societies exhibiting prejudiced cultural plurality, social distancing manifests itself as a form of spatial segregation even within an open urban fabric that does not have physical boundaries. Rather than addressing the achievement of full social integration at the risk of eliminating the richness of local identities, the interactional approach acknowledges the value of intersubjective encounters in the urban space. In this regard, the emerging studies of 'encounter' aim to explore the capacity of social interaction to build mutual learning and solidarity within diff erent socio-cultural groups, even at the risk of con flict. With the fundamental assumption of the social encounter that occurs through particular (spatial and programmatic) conditions within the physical fabric, the paper explores the morphological capacity of the built form to enable the coexistence of diff erences by stimulating encounters. Following a comprehensive review of the literature on the issue, we suggest a multi-scalar approach that involves the macromorphological perspective of spatial con figuration and the micro characteristics of the small public spaces (the so-called 'micropublics'). Accordingly, the paper revisits the notion of 'threshold' as the place of encounter within the city's social fabric. To reveal the interactional capacity of a socially segregated (open) urban fabric for a high possibility of encounters, the paper focuses on the case of the Emek District in Bursa, Turkey, a living fabric composed of divided socio-spatial territories. Following the con figurational analysis of the district, the paper explores some micro-spatial con figurations as thresholds at the street, block, plot, and building levels. Providing a morphological perspective on coexistence within the fragmented social fabric of the city, the research aims to contribute to the extant discussions on liveability from the perspective of interaction and cohesion.
作为表现出文化多元化偏见的城市社会中最棘手的问题之一,即使在没有物理边界的开放城市结构中,社会距离也表现为一种空间隔离形式。与其冒着消除丰富的地方特征的风险来实现充分的社会融合,互动方法承认城市空间中主体间接触的价值。在这方面,新兴的“相遇”研究旨在探索社会互动的能力,在不同的社会文化群体中建立相互学习和团结,即使冒着冲突的风险。通过在物理结构中通过特定的(空间和程序)条件发生的社会相遇的基本假设,本文探索了建筑形式的形态能力,通过刺激相遇来实现差异的共存。在对这一问题的文献进行全面回顾之后,我们提出了一种多尺度方法,包括空间结构的宏观形态学视角和小型公共空间(所谓的“微公共空间”)的微观特征。因此,论文重新审视了“门槛”作为城市社会结构中相遇的地方的概念。为了揭示社会隔离(开放)城市结构在高相遇可能性下的互动能力,本文以土耳其布尔萨的Emek地区为例,这是一个由分裂的社会空间领土组成的生活结构。在对该区域进行形态分析之后,本文探讨了街道、街区、地块和建筑层面的微空间形态作为阈值。本研究从形态学的角度探讨了城市中碎片化社会结构的共存,旨在从互动和凝聚力的角度为现有的关于宜居性的讨论做出贡献。

Does Architecture Ma er to Urban Vitality? Buildings and the Social Life of Streets and Neighbourhoods 建筑有助于城市活力吗?建筑物与街道和邻里的社会生活

Since Jane Jacobs's seminal insights in the 1960s, one of the most emphasized notions in urban studies is the role of architectural and urban form in the 'vitality' and 'liveability' of cities, understood as sets of social and economic qualities such as people's co-presence in public spaces and diversity in local activities. However, can buildings aff ect their urban surroundings? Would diff erent architectural types have diff erent eff ects on the social life of streets and neighbourhoods? These questions are all the more important once we observe a trend in developing countries and other regions – a form of urban growth shaped by detached vertical buildings and gated communities surrounded by setbacks, replacing traditional buildings and creating fragmented urban fabrics. We develop an approach to recognize empirically the urban eff ects of buildings while controlling for systemic factors such as street network eff ects. We apply this method in a large-scale empirical study with twentyfour areas randomly selected in Rio de Janeiro, Brazil. Statistical results suggest distinct eff ects of building types and their features on pedestrian behaviour and land use diversity, helping answer a question that puzzles the spatial imagination: does architecture ma er to urban vitality?
自20世纪60年代简·雅各布斯的开创性见解以来,城市研究中最受重视的概念之一是建筑和城市形式在城市“活力”和“宜居性”中的作用,被理解为一系列社会和经济品质,如人们在公共空间中的共同存在和当地活动的多样性。然而,建筑能影响城市环境吗?不同的建筑类型会对街道和街区的社会生活产生不同的影响吗?一旦我们观察到发展中国家和其他地区的趋势,这些问题就变得更加重要了——这是一种由独立的垂直建筑和被挫折包围的封闭社区形成的城市增长形式,取代了传统建筑,创造了碎片化的城市结构。我们开发了一种方法来凭经验识别建筑物的城市效应,同时控制系统因素,如街道网络效应。我们将这种方法应用于一项大规模的实证研究,该研究在巴西里约热内卢随机选择了24个地区。统计结果表明,建筑类型及其特征对行人行为和土地利用多样性有着不同的影响,这有助于回答一个困扰空间想象的问题:建筑是否有助于城市活力?

Living Convenience in Daily Life and Its Interactive Relationship with Urban Form: A Data-Informed Measurement 日常生活中的生活便利及其与城市形态的互动关系:一种基于数据的测量方法
Q2 Social Sciences Pub Date : 2022-10-01 DOI: 10.2148/benv.48.3.429
Yun Han, Zihao Zhou, Teng Zhong, Y. Ye
As a perceptual quality of life, living convenience is an essential social indicator in contemporary urbanism. A high degree of living convenience in daily life means people can meet most of their needs within a short travel time, bringing a series of bene fits in terms of liveability. However, it was diffi cult to measure this intangible, subjective issue quantitatively. Therefore, analysis of the relationship between various elements of urban form and living convenience is needed. This study explores an analytical approach to measuring living convenience using new urban data and geographic information system techniques. Following a city-scale computation in Shanghai and China, further exploration of urban form and living convenience were conducted. Speci fically, a building-level analysis covering the whole of Shanghai was achieved by computing the level of access and diversity of living services for each building within a 15-minute journey. Diff erent travel pa erns are involved, such as walking, bus, metro, and the distance decay of living service facilities. The largescale spatial distribution of living convenience is mapped to verify the validation of living convenience. Meanwhile, morphological features, block size, intensity of land use, and street pa erns on the street block level were mapped together with their living convenience. Further geospatial statistical analysis helps to bring indepth understanding. In short, this study provides a continuous measurement of an 'unmeasurable' social perception across large-scale areas, which helps to identify neighbourhoods requiring urban planning intervention. The insights into the spatial interaction pa erns between urban morphological features and living convenience can assist in urban design strategy and lead to a more liveable urbanism.
生活便利性作为一种感性的生活品质,是当代城市主义的重要社会指标。在日常生活中,高度的生活便利性意味着人们可以在短时间内满足大部分需求,从而在宜居性方面带来一系列好处。然而,很难对这一无形的主观问题进行量化衡量。因此,有必要分析城市形态各要素与生活便利性之间的关系。本研究探索了一种利用新的城市数据和地理信息系统技术来衡量生活便利性的分析方法。在上海和中国的城市尺度计算之后,对城市形态和生活便利性进行了进一步的探索。具体来说,通过计算每个建筑在15分钟行程内的访问水平和生活服务的多样性,实现了覆盖整个上海的建筑层面分析。不同的出行方式,如步行、公交、地铁,以及生活服务设施的距离衰减。绘制生活便利的大尺度空间分布图,验证生活便利的有效性。同时,对街区层面的形态特征、街区大小、土地利用强度、街道形态及其生活便利性进行了映射。进一步的地理空间统计分析有助于带来深入的理解。简而言之,这项研究提供了对大规模地区“不可测量”的社会感知的连续测量,这有助于确定需要城市规划干预的社区。通过对城市形态特征与生活便利之间的空间互动关系的深入研究,有助于城市设计策略的制定,从而实现更宜居的城市生活。

A high degree of living convenience in daily life means people can meet most of their needs within a short travel time, bringing a series of bene fits in terms of liveability.\u0000 However, it was diffi cult to measure this intangible, subjective issue quantitatively. Therefore, analysis of the relationship between various elements of urban form and living convenience is needed. This study explores an analytical approach to measuring living convenience using new urban\u0000 data and geographic information system techniques. Following a city-scale computation in Shanghai and China, further exploration of urban form and living convenience were conducted. Speci fically, a building-level analysis covering the whole of Shanghai was achieved by computing the level\u0000 of access and diversity of living services for each building within a 15-minute journey. Diff erent travel pa erns are involved, such as walking, bus, metro, and the distance decay of living service facilities. The largescale spatial distribution of living convenience is mapped to verify the\u0000 validation of living convenience. Meanwhile, morphological features, block size, intensity of land use, and street pa erns on the street block level were mapped together with their living convenience. Further geospatial statistical analysis helps to bring indepth understanding.

This study tackles the design challenge of urban in fill development which arises from changes in the urban form and daily living experiences. Using the Web of Science to review relevant literature published over the last decade, we found a signi ficant gap in the study of in fill development: it overlooks liveability and conviviality. To fill this gap, an in fill project in Ard el Golf, Cairo, Egypt, was surveyed using ethnographic research comprising two surveys and semi-structured interviews with site visitors, workers, and residents, and spatial analysis of the changes before and after the project. The results highlight the critical role of functional neighbourhood changes based on their impact on residents', site workers', and users' perceptions of their environment. A six-step strategic framework is presented aggregating the social and morphological dimensions that can off er designers a be er means of confronting the consequences of urban in fill projects with respect to the socio-spatial context for liveable and convivial urban living.
本研究解决了城市填充物发展的设计挑战,这些挑战来自于城市形态和日常生活体验的变化。利用Web of Science回顾过去十年发表的相关文献,我们发现在填充开发的研究中存在一个重大差距:它忽略了宜居性和欢乐性。为了填补这一空白,我们利用民族志研究对埃及开罗的Ard el Golf项目进行了调查,该项目包括两次调查和对现场游客、工人和居民的半结构化访谈,以及对项目前后变化的空间分析。研究结果强调了功能性社区变化的关键作用,这些变化基于对居民、工地工人和用户对环境的感知的影响。提出了一个六步战略框架,汇集了社会和形态维度,可以帮助设计师面对城市填充物项目的后果,并考虑到宜居和欢乐的城市生活的社会空间背景。
