本文以上海老城厢城市景观演变的历史过程为主线,分析了主导这一过程的驱动因素及其相互间的关系。在人为侵占与河浜自然属性的交互作用下,"因浜成路"一直是上海老城厢独具特色的城市扩展方式;19世纪下半叶,传统的环境基础加上西方公共卫生观念的介入,使原来民间层面上的"因浜成路"发展为官方主导下的"填浜筑路",主干河浜消亡的速度骤然加快。这虽然局部改善了老城厢的市容与卫生状况,却对整体的水网生态和后来的城市环境造成了不利影响。这一过程中的内在规律,恰从区域可持续发展的角度,对城市化进程中人与自然间的耦合关系和互动尺度做出了注解,因而具有一定的启发意义。  相似文献

本土安全是近代中国海疆安全战略的终极目标。由于战略目标的局限,中国虽然拥有具备远洋作战能力的海军,但却无法在海军军备建设、军力部署,以及战略战备等方面摆脱海岸防御战略的影响。受本土安全思想的影响,中国的战略决策者在甲午战争中屡失战机,而近代中国海疆安全战略体系也因此崩溃。  相似文献

Ongoing excavations at Olduvai Gorge, Tanzania, reveal tremendous variability among stone artifact assemblages across the Plio-Pleistocene Olduvai Lake Basin during Bed I and lower Bed II times. Theoretically, stone artifact traces of Oldowan hominin land use are determined by the distribution of larger mammal carcasses and arboreal refuge from predation as well as proximity to stone material sources.  相似文献

Inner Scandinavia is one of the Swedish‐Norwegian INTERREG‐A three sub‐programmes, and has been working in operationalizing cross‐border projects in the border area since 1994. To date, several cross‐border strategies have been implemented, one for each programming period of the INTERREG‐A programme. This article investigates whether these strategies can be regarded as a type of cross‐border planning mechanism in promoting territorial development of the border region. It does so by developing a typology, which captures the essentials of spatial planning, against the background of which the article also analyses Inner Scandinavia governance structures, which involves a whole set of interconnected territorial partnerships between five border counties: Hedmark, Østfold, Akershus (Norway), Värmland and Dalarna (Sweden). Here, the main goal is to see if the Inner Scandinavia governance structure, which was recently altered by the inclusion of the Hedmark–Dalarna cross‐border committee, also known as TRUST, is favourable to the implementation of a genuine and long‐term cross‐border spatial plan, with the ultimate goal of reducing the barrier effect and improving the territorial capital along the cross‐border region. Project dokuments and interviews indicate that the existing cross‐border governance model in Inner Scandinavia, led by the INTERREG‐A Steering Committee, produced substantial progresses in reducing the barrier effect, in all its dimensions, and in supporting the territorial development across the border area. Consequently, the role of other cross‐border governance structures should be confined to promoting the active involvement and mobilization of local and regional actors in the cross‐border cooperation process, and in implementing several cross‐border projects with local/regional significance.  相似文献

In the literature, the ‘Overview Maps of Imperial Territories’ or Huangyu quanlan tu 皇輿全覽圖, is mostly referred to as ‘the Jesuit atlas of China’. The reason is that this early eighteenth-century atlas of all Qing China’s territories plus Korea and Tibet is assumed to have resulted from European missionaries importing European cartographic practices. In this essay, I argue that this view is outdated and can no longer be sustained. By revisiting the background of the missionaries’ involvement in cartographic exchanges between Asia and Europe, the techniques used for surveying Qing territories and the production of the resulting atlases, I show that the mapping project behind the ‘Overview Maps of Imperial Territories’ is best understood as a creative answer to the unique needs of Qing frontier management and imperial control, made possible by the integration, in mensurational and in representational terms, of European and East Asian cartographic practices.  相似文献

This paper examines the rural ethnic heritage-inspired transformation of the built environment of a relatively small county town in China. The paper explores the ways village-based ethnic heritage is being repositioned by local leaders as a resource for tourism-oriented revenue generation and for ‘improving’ the ‘quality’ and behaviour of town residents. Viewing heritage as a ‘technology of government,’ the paper provides an analysis based on three interrelated themes: the discourses by which town leaders and planners have conceived the heritage development project as one of improvement, the spatial practices by which those discourses have been realised in the built environment, and the ways residents themselves have appropriated and ‘inhabited’ this new ‘villagized’ city as they go about their everyday urban lives. Based on ethnographic field work, a survey, and extended interviews over a period of four years, the paper finds the town leadership’s faith in the ability of the built environment to shape and improve the conduct of citizens to be overstated. While the town’s transformation has generated a new sense of urban modernity among residents, their ways of inhabiting and using urban space have little relevance to the ‘heritagized’ environment in which they now live.  相似文献

This article focuses on the early years of Federal Union (FU), the leading British federalist association created in 1938. It sets out to demonstrate that FU members heavily disagreed about the economic powers of the future Federation and that these divisions weakened the appeal of the federalist cause. Archival evidence suggests the organisation shifted from economic neutrality, favoured by allegiance to nineteenth-century liberalism, which emphasized the benefits of free trade while keeping a minimum of centralized force in order to prevent interstate rivalries from boiling over into war, to a radical advocacy of supranational planning, aimed at enforcing social rights and welfare entitlements granted to all the citizens of the member-states. This swing to the Left had several implications, including abandoning the prospect of an Anglo-American union, developing a more sympathetic attitude towards the Soviet system, and breaking ties with influential members of the British establishment who had initially lent support to FU, such as Lionel Curtis and William Beveridge. By pointing at the tension between the models of ‘Federation Pure and Simple’ and ‘Federation Plus’, this article also highlights the supple and muddled nature of federalism as an ideology.  相似文献

唐代以前的宣城,走过了由县邑到郡治、由江南西部的行政中心到江南地区的政治腹地与经济沃壤的历程。其间几个关键节点是:楚国置爰陵邑,西汉置丹杨郡,孙吴丹杨郡迁治建业,西晋分置宣城郡,六朝时代之宣城既为近畿要地、又逐渐成长为文化名邦。以南齐谢朓为标志人物的山水诗的创作与影响,既反映了南朝时代宣城的文化特色,也使得宣城成为中国文学史上名副其实的"山水诗都"。  相似文献
