广州城市郊区化的进程及动力机制

随着城市经济社会的发展，我国一些大城市出现了郊区化的初步征兆，开展了郊区化研究有着重要的理论和实际两个方面的意义。广州是我国少数几个已开始进入城市郊区化阶段的大城市之一。本文分析该市郊区化的进程及动力机制，并提出调控对策。     

对我国城市化研究的再考察

本文通过对当前我国城市化研究领域中一些观点的重新考察,以务实的态度提出有关我国城市化进程,城市规模,城市化转移空间,郊区化等问题的探讨性看法,指出城市化既要遵循经济规律,又要发挥政府的适当调控,不拘于西方模式与简单的现象分析,追求城市实质性的健康,有序,持续发展,才是城市化的主旨。     

Quantifying the sustainability of urban growth and form through time: An algorithmic analysis of a city's development

Throughout the latter half of the 20th century, households and cities have changed dramatically. Dense urban developments have given way to lower density suburbanization, while the changing face of the typical family has led to different household makeups. Analyzing how changing urban form influences the sustainability of cities is important for planning future ways in which society aggregates itself. Using current data layers, such as urban boundaries and building footprints, along with past aerial photographs of the city and census data, a detailed reconstruction of the city of Pocatello, Idaho was possible for 1941 for both urban form and population. Using these data sources an algorithmic analysis of various aspects of the city, clustering, compactness, connectivity, and density, was performed on a decadal basis. Results showed an overwhelming trend toward less sustainable development for the city, larger blocks, measured by intersection density, larger distances between houses, fewer people utilizing more space, a more irregularly shaped urban form, an average greater distance from the city center for development, and decreased connectivity, as measured by intersection density. Because the data sources used for this study are readily available to most planning municipalities, the same analysis could be performed on various cities and metros across the United States.     

大连市内部地域结构转型与郊区化

在回顾大连城市内涪地域结构形成发展的基础上,分析了８０年代以来大连城市土地利用结构的总体变化趋势,并尝试提出了大连市内部地域结构模式图。８０年代期间,大连市内部地域结构已开始由单中心集聚型向多中心集聚与扩散并存型转型,而这种转型是大连市效区化现象在城市地域上的空间反映。     

The trials of China’s technoburbia: the case of the Future Sci-tech City Corridor in Hangzhou

ABSTRACT

Set against the wider background of global suburbanization, this paper contributes to the emerging literature on the formation of technoburbia in China, and more importantly, the potential “urban contradictions” accompanying this process. Through a bottom-up empirical exploration of the Future Sci-tech City Corridor in Hangzhou and its embedded Featured Town initiative in particular, we observe how the future of technoburbia in China is by no means free from similar challenges in housing affordability and labor stratification. However, these contradictions are managed entirely differently in China. Nevertheless, the highly planned nature of China’s technoburbia also rubs up against political decentralization, demographic change and economic upgrading, implying significant trials and tribulations along the way.     

北京的郊区化及引发的思考

根据Ｐ．霍尔的城市变动模型，认为城市中心区出现人口负增长是城市郊区化的典型标志，并利用人口普查资料，确定北京在１９８２￣１９９０年期间已经进入了郊区化过程，中心区人口的外迁强度为常住户籍人口的６％，作者对比了中国与西方发达国家明显不同的郊区化机制，并提出了一些值得人们思考和认真对待的独特现象的问题。
