Abstract This article describes a new approach for analyzing data within national historical geographic information system databases that can be used to explore long-term trends in landscape evolution. The methodology is based on clustering together areas with similar demographic characteristics to define urban agglomerations whose territorial extents and populations vary over time. The resulting database can be used in a wide range of ways that allow the empirical study of urban growth and urban sprawl. The article is based on data for England and Wales but given the increasing availability of national historical geographic information system databases for countries around the world, the approach could be replicated for a wide range of different places. 相似文献

AbstractBy 1735, Jean-Baptiste Bourguignon d’Anville had produced forty-one maps of the Qing Empire, or China, a process significantly more complex than scholars have hitherto appreciated. A close study of d’Anville’s maps and their originals has revealed their relationship with the different versions of a Chinese atlas, the first of which was completed early in 1718, the outcome of nearly a decade of collaborative surveying between officials of the Qing Empire and European missionaries. The precise origins of some of the maps are identified for the first time, and the network behind the remarkable intercontinental exchange of cartographical material that allowed d’Anville to produce his China maps is also discussed, thereby illustrating the central role of the French Jesuits, as well as the connection with St Petersburg. 相似文献

This review paper applies a critical geographic perspective to analysis of planning ambition and prospect. Its point of departure is that planning, an applied spatial science, has lacked consistent review from critical geography in recent decades. The consequences of this drift for planning conception and practice are considered, focusing on the influential construct, the compact city. The review finds evidence of serious epistemological and methodological flaws in planning thought and ambition; failings that were earlier identified and analysed in the break with positivism in geographical sciences. The consequences of these limitations for planning thought and practice are considered. Broadly they undermine the ability of the compact city ideal to address what is arguably the most critical threat facing humanity, climate change. Specifically, the proposition that urban density has straightforward influences on human behaviour, including resource use, is without scientific foundation. Planning has a critically important part to play in climate response: securing the resilience and well‐being of an increasingly urbanised human species. Urban compaction may not achieve these ends. 相似文献

Work placements are a well-established part of the curricula of many geographical sciences, as are opportunities for online learning. Whilst many aspects of the learning experience for undergraduates have been given an online makeover the placement has remained a ‘real’ experience. This paper considers the potential value of an online placement and outlines pedagogical and technical aspects of the e-MapScholar Virtual Placement. Findings from evaluation of the first Virtual Placement case study are presented and issues regarding wider adoption are raised. 相似文献

In an era when graduate employability is a key concern, the teaching of geographical information systems (GIS) has become a subject of considerable interest. This paper reports on a study of the GIS student learning experience using student survey data from six UK geography undergraduate programmes. The findings show that although students’ satisfaction levels are generally encouraging, more could be done to capitalize on the opportunities GIS offers both for the discipline and for our students. Recommendations are made for further enhancing the profile and quality of GIS pedagogy in geography curricula. 相似文献

The soil which has developed at any given location is considered to be the result of five interacting factors: parent material, time, climate, topography and biotic factors. This paper discusses the role of these factors in the development of Scottish soils, which fall into three broad categories: leached soils, gley soils and organic soils. The intention is to provide a context for the case studies that follow in later papers. 相似文献

游客安全感的影响要素、形成机理及提升策略研究 总被引:1,自引:0,他引:1
安全感是旅游目的地安全状况的"晴雨表",是游客在旅游目的地最基本需求。本文在对游客安全感的概念进行界定、游客安全感重要性和研究意义进行阐述,以及游客安全感的影响要素进行分析的基础上,探索游客对旅游目的地安全感的认知过程和形成机理,并据此提出旅游目的地提升和强化游客安全感的"四位一体"策略,即培育理性的游客、营造安全的旅游环境、运用现代的安全技术和选择科学的传播渠道。 相似文献

本质为地理过程的全球化与跨国公司相伴而来,其浸入区域、城市具有时空差异性。本文以八家大型跨国零售企业为例,研究全球化浸入中国城市的时空演化过程及影响因素。研究发现:第一,全球化浸入表现出明显的空间推移规律,即稳定的"沿海-内陆"深度格局,以及"东广西疏"转向"南袤北稀"广度格局;第二,全球化浸入中国城市遵循规模等级推移规律,包括人口规模、经济发展水平以及行政等级;第三,人口规模、对外交流水平对全球化的浸入影响显著性稳定,开放政策、城市区位因素弱化,居民收入水平影响增强。 相似文献

流动商贩的分布特征及营业空间界面影响分析——以广州中山大道西路段为例 总被引:1,自引:0,他引:1
流动商贩的空间分布有较大的临时性和变化性,但在各种不同因素的影响下,也具有一定的特征性。研究其分布特征和影响因素对从空间上引导该非正规经济的发展具有积极意义,而已有从空间角度出发的非正规经济研究成果较少。本文主要采用实证研究的方法,选取广州中山大道西路段的流动商贩为典型案例,从空间的角度对流动商贩这种非正规经济来进行研究。研究发现,流动商贩的空间分布具有时间、空间和类型构成三个特征。影响其分布特征的空间界面因素包括界面用地性质、权属以及界面空间特征等,揭示流动摊贩空间集聚的根源,为城市的规划管理和建设提供一定参考。 相似文献

旅游发展初期的自然旅游地社区居民旅游影响感知分类及影响因素在文献中讨论较少。以天堂寨景区为例利用分层聚类法与多分类名义变量逻辑斯蒂回归模型对居民旅游影响感知群体分类并识别其关键影响因素。研究发现:天堂寨周边社区居民旅游影响感知分为盲目乐观派、社区经济挂帅派、谨慎支持派、悲观反对派,分类的关键影响因素为年龄与居住时间、居住村、现在工作。基于深度访谈数据与研究文献分析了相关因素影响居民旅游影响感知群体分类的内在机制。本研究证实了一个事实:即使在偏远的山区农村社会分化也越来越明显,哪怕是针对像旅游业这样的具体议题,同时本研究也呼应了经典社会学中的社会分层理论。 相似文献
