呼和浩特市城市边缘区景观格局动态变化研究

利用GIS技术对1987，2000年两期航空遥感影像进行空间叠加对比分析，从斑块及景观2个尺度对呼和浩特市城市边缘区景观格局变化进行了研究。结果表明：在斑块尺度上，边缘区两期景观结构均以农田景观为基质，研究期内，农田景观、草地景观等缓慢减少，建筑景观明显增多；在景观尺度上，边缘区景观多样性指数趋于增大，优势度指数趋于降低．景观组分趋于复杂化、破碎化和多元化。分析其影响因素可知：经济发展和城市化的加快、政策导向是变化的根本原因，人口的增加、土地利用方式的改变是变化的直接原因。     

Finding work in 2001: urban–rural contrasts across England in employment rates and local job availability

Early results from the 2001 census of England allow a preliminary analysis of joblessness. People in the prime working ages (25–49) are more likely to be in work than those in their 50s, but the differences are quite subtle: in particular, men without qualifications are not much more likely to be in work when they are younger, despite the suggestions that too many men cease working in their 50s. The evidence supports the view that there is a national shortfall of demand for labour, that the low-skilled are the least able to compete for scarce jobs, and older people are the most likely to be unqualified. Moreover there is a strong spatial clustering of areas where job availability has declined or grown least, undermining the government's claim that there were often available jobs near to concentrations of people without work.     

The Singapore River thematic zone: sustainable tourism in an urban context

This paper explores the concept of sustainable tourism and how it applies to urban destinations such as Singapore. As tourism is an important industry in Singapore, in terms of employment, business activity and an income generator, the Singapore Tourism Board is continuously looking at potential avenues to make Singapore a competitive destination. We examine the use of thematic zones in Singapore as a strategy to achieve its ambition of becoming a tourism capital of the world. By focusing on a case study of the Singapore River thematic zone (one of the 11 thematic zones identified by the Singapore Tourism Board), we assess the viability of thematic zones in ensuring sustainable urban tourism. The paper closes with some theoretical reflections and policy implications arising from our key findings.     

基于全球一体化的中原城市群城市竞争力研究

全球化背景下，城市群主导世界经济的趋势不可阻挡，关于城市群的研究随之也越来越受到人们的重视。近几年，中原城市群悄悄崛起，但只是一个雏形，还存在很多问题。为了更好的促进中原城市群的发育，特别是加强城市群内部各城市发挥特长、合理分工、优势互补，进而提升中原地区区域经济的发展水平，文章选用了九大类44项城市竞争力指标，建立了城市竞争力的指标体系，从定量的角度对中原城市群的城市竞争力进行了排序、对比、分析，其城市竞争力排名依次是郑州、济源、洛阳、焦作、漯河、新乡、许昌、平顶山及开封。得到的结论如下：(1)首位城市竞争力强，但还没有发挥核心城市的作用。(2)工业型的城市经济实力竞争力强。(3)农业型城市的经济竞争力较弱。(4)产业竞争力和资金实力是影响城市综合竞争力的主要因子。(5)个别城市的单项指标存在异常点，显现出其优劣势。最后根据分析结果，笔者提出了四点优化对策，为城市群中的城市定位、产业分工、资源优化配置及相应区域互动政策的制定提供决策依据。

A relationship between red tide outbreaks and urban development along the coasts of Guangdong Province

Red tides are one of the main coastal catastrophic events in Guangdong Province of southern China. The comparison between the number of red tide events and the development indexes of cities along the coasts of the province shows that the regional differences in red tide outbreaks has close relations with the coastal urban developments. The cause for an initiation of red tide blooms may be natural factors, while wastewater caused by the fast development of population, industry and aquiculture of the coastal cities enhanced the blooms. It may explain why the two periods of frequent outbreaks of the red tides over the last two decades matched the urban developments in the coastal areas of Guangdong not only spatially but also temporally. The red tides in the first period were restricted only to the coasts of middle Guangdong, where urbanization process was at a higher speed than the other coastal areas of the province. In the second period, fast development of the coastal cities in eastern Guangdong led to an increase in the occurrence of red tides in local sea areas of the same coasts.     

The causes and environmental effects of land use conversion during agricultural restructuring in Northeast China

During the last decade of the 20th century, extensive conversion in agricultural land use took place in Northeast China. The goal of this study is to ascertain its spatial distribution and regional differentiation, determine its causes, and analyze its environmental impact. Especially we attempt to elucidate how institutional constraints have facilitated the change at a time of agrarian restructuring when newly emerging free market was hybridized with the former planned economy. Information on six categories of land use was mapped from interpretation of Landsat TM images recorded in 1990, 1995 and 2000. Most of land use changes took place during the first half of the decade, coinciding with abrupt and chaotic changes in government directives. Farmland was changed mainly to woodland, water body and built-up areas while woodland and grassland were converted chiefly to farmland. Spatially, the change from farmland to woodland was restricted to the west of the study area. The change from grassland to farmland took place in the grazing and farming interlocked west. These chaotic and occasionally conflicting changes were largely caused by lack of stability and consistency in agricultural land use policies promulgated. They have exerted adverse impacts on the local environment, including land degradation, increased flooding, and modified climate regime.     

Place‐based action in Wollongong: the role of union–community alliances in constructing labour geographies of steel

Place‐based action (PBA) features prominently in labour geographies, particularly in restructuring politics, and is consistently employed as an enduring union tactic, yet it remains relatively undervalued in steel restructuring accounts, with common approaches emphasising the class instability and limitations of such action. In contrast, and to redress the apparent imbalance, this paper argues the merit of recognising PBA as a distinct movement‐based politic with specific forms of representation and empowerment. Such an approach should lead to greater recognition and appreciation of the impact that PBA has had historically. To illustrate this, a case study is presented of how local groups used place‐based action in Wollongong to shape steel restructuring politics and industry policy during the 1980s. Although powerful, the influence of PBA diminished at the policy writing stage. Rather than devaluing all benefits from PBA due to such limitations, it is suggested that the constraints on PBA at this point suggests the need for other forms of intervention. It is concluded that the approach suggested here highlights when other tactics are required, strengthening real‐world tactical analysis.     

Black Holes and Loose Connections in a Global Urban Network

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.
