Intensification in the city centre: Barriers to implementation in Regina,Saskatchewan

As cities aim for more sustainable patterns of urbanization, intensification has emerged as a core planning strategy. In 2013, the City of Regina set new intensification targets: absorb 30% of annual population growth through intensification and add 10,000 residents to the city centre by 2035. In the decade since, implementation has been unsuccessful. This study explores the barriers to core area intensification in Regina by engaging with key informants through semi-structured interviews. Our findings identify the most significant barriers as soft market demand, a city centre that is unappealing as a residential context, insufficient political will, an absence of developers who specialize in core area intensification, and unfavourable development economics. These findings illustrate the unique challenges faced by mid-size Canadian cites in disrupting entrenched development patterns and driving development towards the downtown.     

旧城中心区城市衰落研究——以广州沿江西区域为例

在广州这样城市化水平高、经济发展快的华南大都市,也在城区的部分地段出现了城市衰落与更新现象。本文以沿江西RBD为例分析广州城市衰落现象的表征和原因,从物质形态和非物质形态两大方面对沿江西RBD的城市衰落现象进行分析,认为该地区交织存在着结构性衰退、功能性衰退和物质性老化。     

西安市主城区客观生活质量空间格局研究

以街道办事处为研究单元(以下简称街道),选取西安市主城区53个街道作为研究区域,利用Erdas imagine空间分类和建模方法、Arcgis区域分析方法、SPSS因子分析和聚类分析法等对2013年西安市主城区客观生活质量进行评价,并探究其空间格局。结果表明:①在生态环境因素主导下,外围客观生活质量高于接近内城的区域,南北区域高于东西区域,并在总体布局中出现"飞地";②在社会经济因素主导下,客观生活质量以内城为中心向四周辐射,形成放射状格局,同时在曲江等街道出现"异值区";③总体客观生活质量以内城及其南部区域较高,高值区呈现集中连片分布,低值区呈现"马鞍形"分布格局。     

贵阳市道路拥堵状态时空分布规律研究——基于出租车GPS大数据

利用贵阳市出租车GPS数据,建立ArcGIS空间模型计算路段平均行程速度,以空间数据库和ArcGIS空间分析为技术支撑,分析道路拥堵状态的时空演化规律。结果表明：①路网平均行程速度的时间分布特征具有高度相似性,且工作日与休息日分布差异大;②工作日高峰时段拥堵区域分布主要以老城区为主。休息日总体上呈现离散分布趋势,且晚高峰时段交通状况比早高峰更拥堵;③工作日早高峰交通拥堵路段呈由中心核心区逐渐向外围扩散的趋势,晚高峰呈由外围向中心核心区聚拢趋势。休息日早高峰不明显,晚高峰呈现由外围区域向内聚拢趋势。基于上述时空演化规律,从城市功能分散、城市道路网、城市空间发展、城市公交系统等方面讨论了贵阳市城市道路交通优化调整对策。     

Cleveland reimaged: changing news media images of Cleveland, 1985–2015

Beginning in the late 1960s, Cleveland’s public image suffered a series of blows. Riots on the city’s east side claimed the lives of a dozen people and the Cuyahoga River (briefly) caught fire. In the 1970s, deindustrialization ravaged its iron, steel, and auto industries, resulting in tens of thousands of job losses and rising poverty rates. In 1978, Cleveland became the first U.S. city since the Great Depression to default on its bonds. Between 1970 and 1980, the city lost nearly a quarter of its population. In response, business and political leaders developed an economic development plan that attempted to change the city’s image by improving its downtown. This paper analyzes the changing image of Cleveland as conveyed by newspaper headlines and articles from outside the metropolitan area from 1985 to 2015. The results indicate while the city’s external image improved as a result physical improvements in downtown infrastructure and tourist attractions, deteriorating social and economic conditions in the remainder of the city were largely ignored.     

Entre industrie et tourisme: L'évolution du paysage baieriverain à Saguenay,Québec

Between industry and tourism: The evolving landscape of La Baie in Saguenay, Québec La Baie is a borough of the newly amalgamated city of Saguenay, which is defined by its past industrial and maritime development. This area encompassing the Ha! Ha! Bay is characterized by a lush natural landscape, contrasting sharply with the haphazardly built environment and urban fabric. The demolition of the Port‐Alfred pulp and paper mill and the cruise ship terminal project offer the possibility to improve and harmonize this former municipality's landscape. In this article, we will discuss the evolution of the borough's landscape patterns through glimpses of the maritime and tourist tradition, industrial base and the design of downtown commercial space.     

郊区化背景下北京市民城市中心商业区的利用特征

通过微观层面上对北京市居民中心商业中心消费行为的调查,分析郊区化背景下城市中心商业区发展现状,通过市民对城市中心商业区利用特征及其所反映的中心商业区发展问题来认识城市商业空间的变化。虽然城市中心传统商业区仍然在北京市居民消费中保持着重要地位,但是其购物空间已经表现出逐渐向迅速发展的近郊商业区转移的趋势;同时,随着新业态的迅速发展和私家车的普及,中心商业区将面临越发严峻的挑战。     

中心城区金融服务业空间集聚过程与格局研究——以潍坊市奎文区为例

近年来金融服务业发展成为我国经济与地理领域学者关注的新热点。本文通过GIS空间分析和电信黄页统计模拟,对潍坊市中心城区奎文区金融服务业的集聚现状、空间演变趋势进行了实证研究,重点探讨了金融服务业集聚格局的形成过程及演变机制。结论指出:金融服务业空间高度集聚于中心城区CBD内(单核心),集聚主要受城市等级规模和政策推动的影响;较之非银行业(保险业、证券业和其他金融活动),银行业时空演变规律性更强,但总体都呈现"轴向扩散"、"楼宇主导"态势;演变过程和城市主导发展方向、城市功能转型相契合,空间表现为由非均衡向相对均衡发展的格局过渡。
