都市圈发展的新背景、新趋势及其规划响应   总被引:3,自引:0,他引:3  
薛俊菲 《人文地理》2008,23(3):35-39
随着经济全球化的深入发展,城市之间的竞争日益加剧,城市发展越来越呈现出区域化特征,大都市成为了世界城市和城市化发展的主流。在这样的新背景之下,都市圈发展呈现出一些新的趋势,中心性进一步强化并出现多中心的新形式,空间扩散广域化并日趋连绵成片,区域进一步融合并且跨界发展明显。世界各主要都市圈的规划纷纷对这些新形势做出了响应,即以全球性、整体性的视角来审视都市圈发展所面临的问题,致力于形成多中心的空间结构,促进产业扩散与转移,对交通进行网络化整合,并建立类似都市圈政府的机构对都市圈规划进行管理。这些良好的经验可以作为我国都市圈理论研究和规划实践的有益借鉴。  相似文献

ABSTRACT This paper analyses the evolution of city size distribution in the United States throughout the twentieth century. It tests the validity of two empirical regularities studied in urban economics: Zipf's law (the rank‐size rule), and Gibrat's law, or the law of proportionate growth. The main contribution of this work is the use of a new database with information on all the cities (understood as incorporated places), without size restrictions. Our results enable us to confirm that Gibrat's law holds (weakly), and that Zipf's law holds only if the sample is sufficiently restricted at the top, not for a larger sample.  相似文献

A fundamental observation of 21st century cities is that they have become great centers of consumption. In this paper, we seek to understand the geographic variation in consumer behavior. Using Consumer Expenditure Survey (CE), we analyze how consumption differs across 21 major U.S. metropolitan areas, and the association between urban characteristics and consumption. We extend previous geographic analysis of consumption to include luxury goods that are socially visible (conspicuous consumption) and luxury goods that are relatively less visible (inconspicuous consumption). Our analysis shows that conspicuous consumption is more sensitive to an urban context than is inconspicuous consumption.  相似文献

While the illumination of streets by electric streetlights in Western cities is a given today, in the early part of the twentieth century it was a technology whose conspicuous consumption was a status symbol for both individuals and towns. Not long after its introduction, however, electric lighting in cities also became noticeable in its absence. This paper draws on municipal records to consider how ideologies of white supremacy and progress came together to produce the uneven deployment of streetlighting in the small town of Rocky Mount, North Carolina, thus contributing to the city's segregation in the early part of the twentieth century. By tracing the development of hierarchical streetlighting systems, such as General Electric's White Way, I also show how the racialized deployment of streetlighting was aided by large electrical equipment manufacturers. In conclusion, I argue that these insights are crucial to understanding how technologies racialize space, but also how technologies such as streetlighting are central to the production of the spaces in which race is produced and racism takes place.  相似文献

Analytical methods for evaluating accessibility have been based on a spatial logic through which the impedance of distance shapes mobility and urban form through processes of locational and travel decision making. These methods are not suitable for understanding individual experiences because of recent changes in the processes underlying contemporary urbanism and the increasing importance of information and communications technologies (ICTs) in people's daily lives. In this paper we argue that analysis of individual accessibility can no longer ignore the complexities and opportunities brought forth by these changes. Further, we argue that the effect of distance on the spatial structure of contemporary cities and human spatial behavior has become much more complicated than what has been conceived in conventional urban models and concepts of accessibility. We suggest that the methods and measures formulated around the mid‐twentieth century are becoming increasingly inadequate for grappling with the complex relationships among urban form, mobility, and individual accessibility. We consider some new possibilities for modeling individual accessibility and their implications for geographical analysis in the twenty‐first century.  相似文献

Metropolization and the rank/size ’law‘: the Canadian case, 1971–2001 There is currently considerable interest in the process of metropolization. One of the consequences of this process, observed by numerous researchers, is the slower growth and even decline of small and medium cities. From a theoretical point of view, this process is compatible with endogenous growth theory: metropolitan areas offer economic actors certain key factors (access to information, to global networks, etc.) that smaller cities cannot. Concurrently, however, there is a resurgence of interest in Zipf's law and, more generally, in the stability of urban hierarchies. These two bodies of work appear to be in contradiction. However, using Canadian data from 1971 to 2001, we show that whilst metropolization is indeed occurring, this is not necessarily incompatible with a regular urban hierarchy. Indeed, if it is assumed that Zipf's rank‐size rule applies to urban systems in stable socio‐economic contexts, and that this regularity can be disrupted by fundamental social and economic changes, then the current wave of metropolization can be interpreted as a re‐ordering of cities in the face of the major social and economic changes of the 1980s and 1990s, which may eventually lead to a new equilibrium compatible with Zipf's law.  相似文献

High-skilled groups are regarded as a key asset for economic growth and urban development and are thus increasingly targeted by cities. Within this context, the paper analyses the effects of urban decline and intra-national migration trends on cities. The impact of both processes on population development varies considerably between cities and regions and calls for micro- and macro-level policy responses. The contribution focuses on the local impact of the (out-)migration of higher-skilled groups and addresses the research questions: how do local stakeholders and decision-makers evaluate the consequences of the out-migration of highly qualified residents and how are they responding? Our analysis combines the findings of two research projects and draws mainly on qualitative data. The case studies are located in Germany and comprise three medium-sized cities outside of major agglomerations and three large cities within metropolitan areas. The six cities share the common characteristic of urban decline as a result of structural change and have been experiencing population decline. While medium-sized cities lose the highly skilled after they complete schooling, larger old industrial cities lose them after they complete higher education degrees. The paper discusses the implications of intra-national migration for these cities.  相似文献

The early 21st century witnessed a boom in green building in San Francisco and similar cities. Major downtown property owners and investors retrofitted office towers, commissioned green certification, and critically, explored how greening might pay. Greening initiatives transcend corporate social responsibility: they represent a new attempt to enclose and speculate upon “green” value within the second nature of cities. However, this unconventional resource discovery requires a highly partial view of buildings’ socio‐natural entanglements in and beyond the city. I illuminate these efforts and their obscurities by exploring the experience of an exemplary green building in San Francisco, an office tower that has successively served as a headquarters organizing a vast resource periphery in the American West, a symbol and driver in the transformation of the city's own second nature, a financial “resource” in its own right, and most recently, an asset in an emerging global market for green property.  相似文献

During the second half of the twentieth century, internal migration in Turkey played an important role in the redistribution of the population, the concentration of capital in major cities, and the expansion and restructuring of metropolitan areas. To be able to explain the results of this restructuring process, it is important to investigate the provincial differences in migration determinants. The aim of this paper is to investigate the impact of the characteristics of origin and destination provinces and the distances between them on internal migration at the end of the twentieth century in Turkey using global and local forms of regression analysis. Therefore, there are two main parts of the study. The first part includes analyzing the in-migration globally. Second, the spatial distribution of the out-migration with respect to determinants among all the provinces of Turkey is investigated. According to the results, in-migrants are correlated with the characteristics of provinces such as industrial employment, service sector employment and number of university students. Out-migration is investigated for each province according to the aforementioned characteristics of the destination provinces and the distances between them. The results of the study reveal that there are locally varying relationships in out-migration in Turkey.  相似文献

ABSTRACT This paper is an ethnographic and historical exploration of Aboriginal Pentecostalism, which permeated quickly into the Aboriginal community in rural New South Wales in Australia during the early twentieth century. Today the Aboriginal Pentecostal Christians in this region renounce Aboriginal ‘culture’. This, however, does not mean they reject Aboriginality. By examining Malcolm Calley's ethnography on the mid‐twentieth century Pentecostal movement in this region and drawing upon my own fieldwork data, I show the way in which this group of Aboriginal Christians of mixed descent in a ‘settled’ part of Australia have maintained Aboriginality and reinforced attachment to the community through faith in the Christian God, whilst, paradoxically, developing strong anti‐culture and anti‐tradition discourses. This paper advocates shifting the study of social change from a dichotomised model that opposes invading moral orders against resisting traditional cultures, to one that examines the processual manifestations of the historical development of vernacular realities.  相似文献

Fractal geometry can be used for determining the morphological boundaries of metropolitan areas. A two‐step method is proposed here: (1) Minkowski's dilation is applied to detect any multiscale spatial discontinuity and (2) a distance threshold is located on the dilation curve corresponding to a major change in its behavior. We therefore measure the maximum curvature of the dilation curve. The method is tested on theoretical urban patterns and on several European cities to identify their morphological boundaries and to track boundary changes over space and time. Results obtained show that cities characterized by comparable global densities may exhibit different distance thresholds. The less the distances separating buildings differ between an urban agglomeration and its surrounding built landscape, the greater the distance threshold. The fewer the buildings that are connected across scales, the greater the distance threshold.  相似文献

对比北京、天津在各个历史时期的城市核心区建成区的范围,结果发现北京在本世纪上半叶城市核心区总体上扩展速度非常缓慢,个别时段内甚至趋于倒退;相反,天津建成区却是迅速扩张的。造成上述差别的原因主要是二城市在城市性质、城市化驱动机制和帝国主义在华投资政策不同所致。  相似文献

The Asian demographic transition is treated as one aspect of the global Industrial Revolution, which started in the West but now involves the whole world. In fact, the multiplication of per capita income in Asia in the second half of the twentieth century has been the world's fastest. With the rise in female education, urban living and non-agricultural employment, as well as the mortality decline that began early in the twentieth century and government family planning programmes, fertility fell nearly everywhere from the 1960s presaging below-replacement fertility levels. The continent's macro changes are outlined and micro studies of the causes of fertility decline and the delay or forgoing of marriage are drawn from India, Bangladesh, Sri Lanka, Thailand and South Korea. It is concluded that marriages will be increasingly forgone or delayed and that most, perhaps all, ESCAP Asia will this century experience below-replacement fertility. The path followed is much more likely to resemble that of Mediterranean Europe than Northern Europe.  相似文献

In this article, the author uses a slum clearance project in Lexington, Kentucky, as a lens through which to examine the spatial dynamics of racial residential segregation during the first half of the twentieth century. At the time, urban migration and upward socioeconomic mobility on the part of African Americans destabilized extant residential segregation patterns. Amid this instability, various spatial practices were employed in the interest of maintaining white social and economic supremacy. The author argues that such practices were indicative of a thoroughgoing reinvention of urban socio-spatial order that in turn precipitated the vastly expanded scale of residential segregation still found in U.S. cities today. Evidence of this reinvented ordering of urban space lies in the rendering of some long-standing African American neighborhoods as “out of place” within it and the use of slum clearance to remove the “menace” such neighborhoods posed to it.  相似文献

This paper considers the intersection of Spiritual Motherhood, early childhood education and child welfare in early twentieth‐century Edinburgh. Its focus is St Saviour's Child Garden (SSCG), which opened in the Canongate, in November 1906, part of the Free Kindergarten movement that emerged in Europe and North America in the late nineteenth century. The paper focuses on the SSCG's founder Lileen Hardy, in order to trace the development of this new approach to child welfare and women's work in Britain. It discusses her training at the Sesame House for Home‐Life Training in London, her move to Edinburgh, and the network of predominantly women reformers, whose interests ranged from urban reform to medical welfare, she found there. It shows how this network facilitated the founding of the SSCG and discusses the form it took and Hardy's implementation of a modified form of Froebelian praxis. In so doing its concern is to show how Free Kindergarten forms part of a wider history of social welfare and urban reform as well as to the history of early childhood education, and to move attention away from the men usually associated with innovations in Scottish social reform like Patrick Geddes, and onto a group of women who created a women and child‐centred proto‐Welfare State in pre‐First World War Edinburgh.  相似文献

‘Imperial culture’ is a concept coined by British historiography to describe the influence of imperialism on metropolitan British culture. Although it is now used in other national historiographies as well, it would appear that we have not yet realised the concept's full potential. This article, drawing on recent scholarship emphasising the transnational connections in European imperial cultures, investigates the implications of seeing imperial culture as a European phenomenon and as a European mentality. For this purpose, this article uses the narrative that was propagated at a specific national practice where empire met a metropolitan European society as a case study: missionary exhibitions in the Netherlands in the first half of the twentieth century. Here, Catholic and Protestant missionaries displayed objects from the indigenous, colonised populations who they were trying to convert and hereby legitimised and underpinned imperialism in Dutch culture. However, their significance went deeper than that. This article argues that the missionaries’ narrative transcended the national level and promoted ideas of Christianity as a European religion and civilisation as a European trait. A European community based on religious, cultural, and racial traits was set against a generic non-European heathen world. However, national and denominational frames of reference also remained in place. With this case study, the article explores the possibilities and difficulties that arise from studying imperial culture as a European mentality.  相似文献

This paper examines the historiography of ancient town planning and the Roman city, with particular attention to its origin in the town planning debate of the early twentieth century. It questions the existing dichotomies, ‘civilised'/'uncivilised’, ‘classical'/'barbarian’, ‘urban'/'proto‐urban’, that have characterised this history. Finally, the paper examines the effect of the separation of the academic disciplines of classics and archaeology in Britain upon the history of ancient urbanism.  相似文献

This article examines the pivotal role played by two canonical texts in shaping the political subjectivities of suffragists in late nineteenth‐ and early twentieth‐century Britain. Read and discussed by three generations of British feminists, John Stuart Mill's Subjection of Women and Giuseppe Mazzini's Duties of Man shaped suffragist thinking on relationships between family, state, and citizenship and provided impetus for the creation of new kinds of argumentation and organisations for women's political activism.  相似文献

The case of Madrid is used as empirical focus to propose a new classification of the metropolitan region urban medium-sized or secondary city system. Based on a methodology that integrates the morphological (size, location and socioeconomic history) and the functional dimensions (centrality index, advanced producer services (APS) concentration and commuting), the article compares new employment centres—cities with metropolitan origin—and historical cities—previously free standing cities, progressively integrated in metropolitan processes. The results show a distinction between (1) metropolitan cities, with a traditional intermediation role, and (2) metropolitan intermediary cities, that include an additional quality to their traditional intermediation role, that of concentrating APS. The article confirms that some medium-sized cities—metropolitan intermediary cities—linked to different origins and up to 100?km away from the metropolis are more visible in the global scene and are establishing an emerging global multicore-network at a metropolitan-regional scale.  相似文献
