都市社区旅游国际化的"新天地"模式 总被引:3,自引:0,他引:3
都市社区旅游的国际化是大都市国际化的先导和符号。大都市社区旅游不仅是都市旅游空间组织和发展的重要模式,也是旅游产品国际化的重要表现形式。从社区国际化的视角思考都市旅游目的地建设,实现旅游国际化与社区发展的良性互动,是都市旅游发展的新途径。社区旅游国际化的关键在于社区旅游环境氛围的文化底蕴地方化、旅游服务质量的国际化、接待游客来源的国际多元化、旅游产品供给与体验的国际时尚化。基于上海石库门社区文化特色的“新天地”模式,具有都市社区旅游国际化的示范和启迪效应。 相似文献

An atypicality index has been used to compare the chemical compositions of 11 British prehistoric implements (axes and axe‐hammers, and a mace) with previously suggested and likely sources in South Wales (Group XIII spotted dolerite from the Carnmenyn area, and Group VIII rhyolite from Carnalw). Atypicality indices together with mineralogy indicate that only two out of six supposed Group XIII implements are likely to be Group XIII, and only one of the five rhyolite implements is likely to originate from Carnalw. These results provide statistical support for earlier provenancing of seven of the implements, and provide the first geochemical source information for four implements. The results illustrate the usefulness of the atypicality index in archaeology, and support the idea that Groups XIII and VIII comprise a larger variety of chemical types than previously thought. Further work is now needed to determine how prevalent this variety is within these implement groups. 相似文献

1990年以来兰州市的城市空间扩展研究 总被引:6,自引:1,他引:5
在GIS技术支持下,根据兰州市1990年、1995年和2000年的土地利用现状图,以及2004年的卫星影像图,提取了1990年以来兰州市的城市空间扩展信息,并利用年均扩展指数(AGI),分析了兰州市1990-1995年、1995-2000年和2000-2004年三个研究时段城市空间扩展变化的空间分异特征。研究表明:1990-1995年处于快速扩展期,1995-2000年处于缓慢扩展期,2000-2004年处于高速扩展期。城市空间扩展主要发生在城关区和安宁区,主要表现为圈层式扩展与内部填充式两种过程。最后,探讨了兰州市空间扩展机制,重点采用相关分析法分析了兰州市空间扩展的主要影响因素。 相似文献

This paper presents an empirical analysis of hierarchical tendencies and functional patterns in the development of Mainland China’s space-economy by operationalizing the concept of “megaregions.” Drawing on the burgeoning literature on megaregions, we first argue that under conditions of economic globalization the megaregion concept does indeed present an effective tool to study the spatial agglomeration of the key components of China’s economic development. Second, we analyze the development status and the key functional characteristics of 16 prospective Chinese megaregions by constructing an index system consisting of 5 functions and 36 indicators. Third, we calculate an entropy index to rank megaregions according to their overall development status and reveal functional differences by applying cluster analysis. We find that the Yangtze River Delta, Beijing–Tianjin–Hebei Metropolitan Area, and the Pearl River Delta stand out, identify different varieties of megaregions according to their dominant functional characteristics, and explore the main policy dimensions of the persistent west–east divides observed. The paper is concluded with a discussion of potential avenues for future research. 相似文献

This paper considers the epistemic career of visual media in ethology in the mid-20th century. Above all, ethologists claimed close contact with research animals and drew scientific evidence from these human-animal communities, particularly in public relations. However, if we look into the toolboxes of comparative behavioral biologists, it becomes evident that scientifically valid research results were primarily obtained by experimenting with model images. These visual specimens tell a technical story of the methodological requirements in behavioral science necessary to bridge everyday observations between the laboratory and the field. By neutralizing individual traces of animal bodies as well as their observers, they prompted the abstraction of ethological hypotheses. The case study of East-German biologist Günter Tembrock (1918–2011), who maintained his own collection of newspaper clippings, drawings, photographs, and films, offers a new perspective on the methodological development of this field. Furthermore, this article contributes to a scholarly discussion geared toward expanding the spaces of ethological research. My analysis of the image collections of the Forschungsstätte für Tierpsychologie presents the archive as a relevant site of study in the history of ethology. 相似文献
