This article investigates the relationship between urban gardening and planning by building upon the results of field research on gardening initiatives in the city of Rome, Italy. The work is aimed at suggesting that, while often associated in geography and planning literature with urban informality practices (e.g. accidental city or self‐made urbanism), urban gardening actually presents the character of a distinctive form of people's interaction with urban space, here defined as “informal planning”. This includes practices that are intentionally put forward by local dwellers with the intention of urban space planning and organizing public life in the absence of legal definition, guidance and funds provided by public authorities or the private sector. Urban gardening cases in Rome exemplify the emergence of informal planning and show how, by questioning the counterplanning tradition that understands urban gardening as an antagonist spatial practice opposing institutional planning, informal planning can open up collaborative possibilities. A new mode of interaction between citizens' agency and the formal planning initiatives of local administration can lead to creative solutions to address some of the problems associated with the neoliberal transformation of the city space, most notably the decrease in public space and its deterioration.  相似文献

In summer 1990, the Commission of the European Communities published a "Green Paper" on the urban environment as a first step toward establishing an integrated policy for European cities, focusing on the revaluing of public space whose degradation is considered a symptom of a deep-seated developmental and environmental crisis. This article addresses the questions raised by the Green Paper: the needs to which it responds, and the results to be expected; the extent to which the proposed themes cover a "full range of difficulties facing Europe's conurbations," given the diversity of urban space in the old continent. Finally, it considers the paper's relevance for Greek cities: this highlights the existence of non-discussed city typologies within the single European space, which means that the concept of the European city should be carefully re-examined and based on the social and cultural plurality and complexity of the European cities, rather than stressing the existence of a single city-type. The Green Paper, when seen not as a text of generalizing assumptions or an instrument for action, may very well act positively to open a debate that will reveal and answer the specificities and the problems of each city.  相似文献

兰州城市居民意象空间及其结构研究   总被引:3,自引:0,他引:3  
通过问卷的方式对兰州城市居民的意象空间进行了调查,从266份认知地图中提取和统计相关数据,据此分析了兰州城市居民空间认知的基本类型、构成要素和发展阶段。研究表明,兰州城市居民空间认知的基本类型不仅包括西方学者提出的序列型与空间型,而且还包括单体型;空间认知的构成要素并没有超出Lynch提出的5种:道路、边界、区域、节点和标志物,但各要素所占比重要相对均衡一些;就空间认知的发展阶段而言,初、中级的连接发展阶段和邻里描绘阶段所占比重高达96.61%,说明居民对兰州城市的空间认知水平普遍较低。最后,根据各种地物和要素出现的频率概括出了兰州城市的意象空间结构,发现它与现实中兰州城市空间格局及其重点十分相似。  相似文献

This paper examines issues of power and resistance in “divided cities”. Basing my analysis on fieldwork I carried out in Skopje, Macedonia, I look at how urban space may be constructed and used by hegemonic groups as a means of asserting their power and how, in turn, the city may be a place of resistance where power is contested and public space reappropriated. Drawing on Lefebvre's perspective on the production of space, I compare the conceived city to the lived city and examine how urban inhabitants may resist the division of the city and challenge hegemonic representations. I also draw on Debord's psychogeography to define an artistic, active and participatory approach to urban space through which the inhabitants may re‐conquer their right to the œuvre and to the city. I argue that the city as a lived environment may offer narratives other than division and that there are alternatives to the divided city.  相似文献

从现代人本主义思维出发,以城市社会地理学原理,即从社会空间结构与社区规划角度,探讨城市居民的生活空间的质量构成,体现在城市要满足各阶层居民(社会)生活的空间结构上。而城市(社会)生活的空间结构的健全与否取决于生活空间行为的社区体系与场所体系的空间构成上。主要体现在居民以居住为主的生活行为对立的居舍类型的可获性上。由此,不同阶层居舍类型体系是城市(社会)生活空间质量的区域基础,其空间分布类型的可获性决定对应阶层人群能否获得以居舍为主的生活空间。本文首次从居民选择居住地行为规律以及形成的城市居舍类型空间结构演化的理念下论及城市社会区域空间体系公正配置与空间控制原理。  相似文献

In this paper, I bring together ideas of ‘diaspora space’ and ‘the right to the city’ and empirically demonstrate how the formation of diasporas is frequently dependent on migrants attaining certain rights to the city. These rights, I argue, are conditioned and attained by the interplay of urban structural context with the place-making strategies of migrants. Drawing on 8 months of ethnographic fieldwork, I demonstrate that Moroccan migrants in Granada, Spain, have achieved a partial right to a neighbourhood of the city, producing a multi-sensory, self-orientalised diaspora space. First, I show that certain urban conditions in Granada provided a foothold for Moroccan migrants to begin to form a diaspora and transform urban space. Second, I demonstrate that through the mobilisation of a strategically self-orientalised cultural capital, the diaspora have partly appropriated the valuable history of Al-Andalus, a key component in the city’s tourist imagery. These factors and strategies have enabled Moroccan migrants to gain a right to have a visible presence in the city, a right to produce and transform urban space and a right to spatalise diverse identities – all key rights, I argue, in the formation of a diaspora.  相似文献

ABSTRACT Motivated by the newly established Chinese urban land markets, we develop a theoretical model that unifies the “closed” and “open” features of the classical monocentric city model. The model features interactions between permanent urban residents and migrants and exhibits a distinctive equilibrium pattern. The theoretical model is tested empirically, using recent Chinese city‐level data. The empirical findings indicate that market forces now play an important role in urban expansion and land price formation, while various forms of government planning are still influential. Our results show that migrants exert a less pronounced impact than the classical “open” city model has suggested.  相似文献

在全球竞争时代,大事件营销已经成为城市政府实现增长策略的重要工具。文章引入空间生产的分析视角,对城市大事件营销的物质空间效应、社会空间效应、经济与政治效应进行了客观的评述,这些影响有正面的,也有负面的,从而揭示了通过大事件营销实现城市空间生产过程的本质。文章指出,大事件营销成为城市在全球化流动空间中增强对资本等发展要素粘性的重要媒介,实现了从流动空间向场所空间的转变,对城市的空间、经济、社会与政治关系等都产生着深刻的重塑作用。但是,更加关注如何将外向增长机遇与城市内生增长能力进行更好的结合,是非常必要的。  相似文献

Urban green space is a key subject of actual urban negotiation processes on how the city shall develop. Visions of the ideal city are reflected in the meanings currently ascribed to urban gardening. Thereby the relation between human and nature as well as between build and natural environment in the city plays a central role. Results from different Swiss cities show that allotment gardens as well as newer forms of urban gardening are oscillating between a compensatory and a complementary understanding of nature, and they equally combine the desire for pristine nature with the demand for functional green space in the city.  相似文献

Culture‐led projects have long been part of strategies to regenerate cities in advanced capitalist economies. In recent decades those projects also have become a focal point of urban development in post‐socialist cities. This study argues that an attempt to reimage(in)e the city of St Petersburg through its culture‐led flagship project, Mariinsky Theatre–2, has generated significant changes not only to its built fabric, but also to its social fabric. In the context of a post‐socialist city, this study examines how the urban space of the historical centre is being contested by its urban users, often on the basis of differences in perception, including the impacts of the culture‐led project on those perceptions. Civic awareness about social exclusion and inclusion in urban space is on the rise in this post‐socialist city.  相似文献

Cities today are typically framed as sites of capitalist development, while the urban park is theorized as an indirect response to the emerging hegemony of industrial production in the nineteenth century. Yet, this historical framing tells us little about the process through which our notions of ‘the city’ and of ‘nature’ are produced, or how this knowledge affects the formation of urban people's identities. The discursive formation of the capitalist city can be traced to specific historical moments, one of which is the construction of urban parks during the mid- to late-nineteenth century, which I argue was instrumental in producing a new knowledge of the capitalist city by creating a boundary between the social space of the city and the natural space of the park. Using Philadelphia's Fairmount Park as a case study, I draw on archival photographs and annual park commission reports to explore the formation of park subjects during this period and shed light on diverse economic practices that were once widespread in and around the city but whose erasure was ultimately a prerequisite for the successful formation of an urban discourse organized around the construction of the city/nature boundary.  相似文献
