AUTOMATED ISOCHRONES AND THE LOCATIONS OF EMERGENCY MEDICAL SERVICES IN CITIES

A method is described for the automatic calculation and graphical reproduction of isochrones around emergency medical centers in large cities. The isochrones are set for different time standards and for varying traffic conditions. The technique is based on the concept of a velocity field. It permits a rapid evaluation of coverage standards under different operating conditions.     

西南地区文化产业竞争力研究

中共十八大报告对文化产业的发展提出了新的要求,文化产业作为一个新兴产业,越来越受到各国各地区的重视。西南各省市区位于中国西南边陲,经济欠发达,科技水平较低,但文化资源丰富,民族特色得天独厚,文化产业正在日新月异的发展。然而由于地理位置,资源环境,生态环境等方面的不同导致西南各省市区文化产业发展极其不平衡。因此,使用主成分分析法对西南各省市区的文化产业竞争力进行分析和研究,进而提出西南地区发展文化产业的模式及相关政策建议。     

广州市中心城区基本医疗服务空间分布研究

以广州市最新一轮行政区划结果与医疗机构相关数据为基础,运用ARCGIS和SPSS软件,通过构建基本医疗服务优势度模型,对广州市中心城区医疗服务状况进行评价。得到以下结论：（1）形成以老城区组成的团块状高优势度区域为中心,优势度分值自中心向外围区域呈现环状递减,并且优势度高分值区域有向市区东部及北部延伸的趋势;（2）基本医疗服务能满足大部分居民的需求,特别是越秀、海珠、荔湾的部分区域优势度高,但个别区域基本医疗服务现状差强人意,亟待改善。     

西南三省城镇的职能分类

本文采用H·J·纳尔逊(1955)的城镇职能分类法,根据我国1979年国家统计资料,对四川、云南、贵州三省的城镇进行了类型研究。     

福州市土地利用变化及其生态系统服务价值响应

土地利用变化会相应的导致区域生态系统环境发生变化。以福州市作为研究区域,利用福州市2002～2008年土地利用变更数据,分析这7年的土地利用变化状况;同时结合国内外生态服务价值研究成果,测算福州市7年来生态服务价值的变化。研究结论：（1）福州市2002～2008年间建设用地对农用地的侵占导致福州市生态系统服务价值由2002年的383.18亿元减少到2008年的380.05亿元,但总体变化幅度不大。（2）由于缺少系统的理论与方法,文中没有对福州市的海域生态系统服务价值进行计算。

ACCUMULATION,LEGITIMATION, AND THE PROVISION OF PUBLIC SERVICES IN THE AMERICAN METROPOLIS

The provision of public services by the local state involves the full range of politics, structural forces, and actors at work in the world system. Materialist theory provides a means by which these disparate elements can be integrated as the state performs its two primary functions: maintaining conditions favorable for the accumulation of capital and ensuring the legitimacy of the economic and political systems. National and local governments attempt to provide conditions in specific places that will foster growth; the politics of production characterize these efforts. On the local level the state also provides a forum in which the demands of less organized and powerful interests can be heard, as it attempts to maintain the loyalty of the public; the politics of consumption characterize this activity. An empirical analysis of local government expenditures for public services in the United States indicates the role that public services play in the performance of these two functions of the capitalist state.     

THE INTRAMETROPOLITAN LOCATION OF SERVICES IN THE UNITED STATES

In metropolitan areas, firms trade-off land and information costs. Firms that gain the most from access to the knowledge and know-how of other firms in the same sector are willing and able to pay for expensive central city land. We found that legal services, advertising, and accounting and auditing services are the most centralized services in the 74 largest metropolitan areas of the United States. Maps of seven fast-growing business and professional services in Phoenix, Arizona, show that central city services are mainly located in the CBD. Using a logarithmic function, we found that service jobs are more decentralized in the larger metropolitan areas and in metropolitan areas outside the Northeast. Analysis of disaggregate service sectors shows significant intersectoral variation in this relationship.     

泛珠三角14个重点旅游城市旅游发展现状比较和类型分析--兼论各类城市的旅游发展对策

THE CONSERVATION CYCLE IN THE CITIES OF THE DEVELOPING WORLD: IMPLICATIONS FOR AUTHENTICITY AND POLICY

Urban conservation in developing countries takes place despite limited funds, strong forces of deterioration, and the lack of popular and private-sector support. These challenges contribute to the existence of a conservation cycle in which policies evolve from an emphasis on monuments, to largely cosmetic enhancement schemes, to area-improvement projects, and, finally, to more ambitious removal programs. The four stages of the cycle are illustrated with reference to the historic center of Quito, Ecuador. Escape from the cycle to a condition of sustainability is achieved when the private sector is motivated to invest on a scale that generates permanent upgrading. This motivation becomes possible with the area scheme and is a virtual certainty if removal measures come to dominate conservation policy. However, progress through the cycle diminishes the traditional heterogeneity of social groups and ways of life that characterize the historic centers. Reference to the concept of authenticity highlights the tension between architectural conservation, a changing human environment, and the meaning placed in that environment. Although interpreting the meaning of conservation presents problems for policymakers, an improved awareness should contribute to a more sensitive policy.

THE GHETTO MODEL AND ETHNIC CONCENTRATION IN AUSTRALIAN CITIES

Urban geographers frequently use the concept of the ghetto as a linguistic device for describing the concentrations of ethnic groups (mainly though not exclusively immigrants) within the residential fabric of metropolitan areas. The validity of this metaphor has been questioned by a number of analysts, however, notably Peach who has provided strong evidence of the lack of ghettos in Great Britain. This paper adapts his approach to the Australian situation and explores the existence of ghetto-like concentrations in its metropolitan areas. It finds very little evidence of such exclusive residential areas there, casting further doubt on the general applicability of the ghetto model. [Key words: ghetto, cities, birthplace, Australia thresholds.]     

TELECOMMUNICATIONS AND THE GLOBALIZATION OF FINANCIAL SERVICES*

Financial services are undergoing a major period of internationalization. National markets are interlinked by telecommunications, a process induced through deregulation and new communications technologies. This paper reviews the recent, intertwined trends in the finance and telecommunications industries in light of urban and regional restructuring theory, cites several company-specific examples, explores the impacts on the international urban hierarchy and the labor process (e.g., back offices), and assesses the role of teleports. Finally, it offers an agenda for further research.

辽宁省沈大双核与其他城市的分化

分析辽宁省沈阳大连的核心作用,将辽宁省城市分为核心城市组(沈阳、大连)和外围城市组(其他城市);再以人口、GDP和人均GDP为基本指标,利用Theil指数计算组内差异、组间差异和总体差异,利用KZ指数模型计算核心城市与外围城市的分化。结果表明沈阳大连与其他城市的分化总体上加大;分化具有波动性特征,分化在地域空间上也体现为辽中南城市群被以沈阳为核心的辽中城市群和以大连为核心的辽南城市群取而代之,其他地区城市聚集不明显;沈阳大连与辽宁省其他城市的分化是自然和社会经济因素综合作用的结果,分化机制主要有地理位置的先导机制、区域发展战略的催化机制和政府规划的引导机制。     

小城镇可持续发展的区域透视

小城镇可持续发展是当今可持续发展研究的重点领域之一，目前绝大部分研究仅仅局限于就小城镇论小城镇，笔者认为区域才是小城镇可持续发展的基础，是小城镇赖以生存的环境，小城镇是区域社会生产力发展到一定阶段的产物，小城镇和它所在的区域是互相依存、互相促进的。只有当二者为互动关系时，才能促进小城镇可持续发展。笔者从理论与实证研究角度，阐述影响小城镇可持续发展的区域环境、区域经济、区域社会、区域与小城镇的整体性等因素，认为小城镇可持续发展是一个多层次、多因素的庞大的系统，推动其发展的包括内部环境与外部环境，并构建区域与小城镇可持续发展的“火箭”模型。
