基于空间数据库的山东城镇发展水平的空间统计分析     

单宝艳 《测绘科学》2008,33(4)

基于GIS空间数据库,对山东省108个城镇的综合发展水平进行了空间统计分析。首先选用了反映城市综合发展水平的14项指标,并进行了主成分分析,得出反映城镇综合发展水平的综合指标,并分析了山东省各城镇的综合发展水平与分布状况。然后利用该综合指标,对各个城镇进行了空间统计分析,通过计算全局空间自相关指标,分析认为山东省各城镇综合发展水平总体上未呈现空间相关关系;通过计算局部空间自相关指标,分析认为山东省68.5%的城镇分布存在非相似空间集聚特征。  相似文献   

Beyond world cities: Central America in a global space of flows   总被引：1，自引：0，他引：1  

Ed Brown  Peter J. Taylor  & Gilda Catalano 《Area》2002,34(2):139-148

Central America is a region without a world city. Traditionally, the region's national projects have been based upon openness to the world economy: how do the region's contemporary transnational projects connect to the world economy under the new conditions of openness that is contemporary globalization? Focusing upon advanced producer services, three connections into the world city network are identified: global service firms operating directly in Central American cities, local service firms operating indirectly through extra-regional world cities and global service firms operating through Latin American regional offices. Miami is confirmed as the primary world city through which Central America connects into the world economy  相似文献   

Exploring the attractions of city centre living: evidence and policy implications in British cities   总被引：1，自引：0，他引：1  

Andrew R. Tallon  Rosemary D. F. Bromley   《Geoforum》2004,35(6):771-787

The British city centre has been the focus of dynamic housing development and repopulation strategies as a key dimension of the government's urban renaissance programme. Through large scale interview surveys in the provincial city centres of Bristol and Swansea, this paper explores the positive and negative features of city centre living, and how these vary amongst a range of social and physical characteristics. The findings suggest that the practical and mundane attractions of city centre living are more important than the more widely publicised lifestyle and cultural attractions of the city centre commonly emphasised in the gentrification literature. Moreover, the research points to differences in attitudes between age groups, with younger adults placing greater value on the range of social and cultural activities in the city centre, whilst older people express high levels of satisfaction with the attractiveness of the environment. A number of policy implications emerge to encourage inclusive marketing strategies within the continued urban renaissance, particularly to challenge the negative perceptions and promote the varied attractions of city centre living to a mix of social groups.  相似文献   

Black Holes and Loose Connections in a Global Urban Network   总被引：1，自引：0，他引：1  

John Rennie Short 《The Professional geographer》2004,56(2):295-302

This paper introduces the concept of black holes and loose connections in a global urban hierarchy. Black holes are defined as large cities, with a population of over 3 million, that are not classified as world cities. The paper draws upon a classification that uses advanced producer services as an indicator of world city status. Large, nonworld cities are identified, and provisional ideas about explaining their position are outlined. Connectivity and population data are used in a simple regression analysis to identify loose connections: cities whose connectivity is less than that predicted by their population.  相似文献   

Urban re-generations: afterword to special issue on the politics of urban greening in Australian cities     

Donna Houston 《The Australian geographer》2020,51(2):257-263

ABSTRACT

‘Urban re-generations' is written as an afterword to the special issue of Australian Geographer on ‘The Politics of Urban Greening in Australian Cities'. The collection prompts a deep questioning of reparative and regenerative work associated with greening, green spaces and green infrastructures. The climate-driven 2019-2020 bushfire crisis and COVID-19 have amplified the visibility of the more-than-human connectivity of our cities and the deep underlying structures of social and environmental inequity underpinning a variety of urban green spaces and agendas. Inspired by the articles in this special issue, the afterword explores how we might call back the grammars and practices of regeneration from their service to the neo-liberal, settler-colonial city and instead nurture reparative de-colonial practices that aid in the collaborative work of re-composing, becoming into better relation with, and working in modes of situated historical and cultural difference, with green and just cities.  相似文献   

复杂地形城市多尺度气流对大气污染影响的研究进展     

李霞 《沙漠与绿洲气象(新疆气象)》2016,10(6):1-10

复杂地形城市一般建立在山地、丘陵、沿海地带。复杂地形下的大气污染传输、扩散机制是一个复杂的问题。本文依据城市地形地貌将复杂地形归类为河谷地形、三面环山临海地形、盆地地形、马蹄型地形和峡口地形。结合国内外对这五类地形下城市污染物传输扩散及污染形成机制的研究成果,介绍了不同地理位置、不同复杂地形城市多尺度气流相互或交替作用的特点及其对污染传输扩散的影响,期望能够为其它复杂地形城市污染形成机制研究和大气污染防治提供一些借鉴。  相似文献   

Emerging Chinese Cities: Implications for Global Urban Studies   总被引：2，自引：0，他引：2  

Fulong Wu 《The Professional geographer》2016,68(2):338-348

Chinese cities are emerging in multiple senses: They have created new physical spaces to accommodate the fast urbanization of the country but have also developed new properties and characteristics along with urban transformation. The novelty created by emerging cities in China is not easily covered by Western urban theory. This article examines the dynamism of Chinese urban transformation, especially political economic changes vis-à-vis so-called neoliberalism, and spatial outcomes as diverse and contrasting spaces of formality and informality. Finally, this article speculates on implications for global urban studies.  相似文献   

Visualising 30 Years of Population Density Change in Australia’s Major Capital Cities     

Neil T. Coffee  Jarrod Lange  Emma Baker 《The Australian geographer》2016,47(4):511-525

ABSTRACT

This study uses a novel spatial approach to compare population density change across cities and over time. It examines spatio-temporal change in Australia’s five most populated capital cities from 1981 to 2011, and documents the established and emerging patterns of population distribution. The settlement patterns of Australian cities have changed substantially in the last 30 years. From the doughnut cities of the 1980s, programs of consolidation, renewal and densification have changed and concentrated population in our cities. Australian cities in the 1980s were characterised by sparsely populated, low density centres with growth concentrated to the suburban fringes. ‘Smart Growth’ and the ‘New Urbanism’ movements in the 1990s advocated higher dwelling density living and the inner cities re-emerged, inner areas were redeveloped, and the population distribution shifted towards increased inner city population densities. Policies aimed at re-populating the inner city dominated and the resultant changes are now visible in Australia’s five most populated capital cities. While this pattern has been reported in a number of studies, questions remain regarding the extent of these changes and how to analyse and visualise them across urban space. This paper reports on a spatial method which addresses the limitations of changing statistical boundaries to identify the changing patterns in Australian cities over time and space.  相似文献   

Spatial Concentration in Australian Regional Development,Exogenous Shocks and Regional Demographic Outcomes: a South Australian case study     

Peter Smailes  Trevor Griffin  Neil Argent 《The Australian geographer》2016,47(4):527-545

ABSTRACT

As a tribute to the massive contribution of our friend and colleague Graeme Hugo to the population and settlement geography of Australian rural areas, this paper presents a longitudinal study from his home State. It forms part of a wider study of the long-term demographic relationships between Australia’s rapidly growing regional cities and their surrounding functional regions. Of particular interest is the question of what effect the accelerating concentration of population and economic activity into a given regional city will have for the longer term demographic sustainability of its functional region as a whole. Taking the case of Port Lincoln, regional capital of most of South Australia’s Eyre Peninsula, it examines the nature of change in the functional region over the period 1947–2011, and investigates the forces feeding, and partly counteracting, the population concentration process, informed by concepts of evolutionary economic geography. In particular it traces the demographic impact (particularly differential migration and ageing trends) of exogenous shocks to the region’s essentially primary productive economic base during the period of major change from 1981 to 2011.  相似文献
