木材树种的鉴定是古木结构建筑维修和保护的基础性工作。为配合建水县指林寺大殿修缮保护的需要,为修缮树种选用提供依据,了解木文化的特点。本研究对建水指林寺大殿古建筑主要木构件进行了树种鉴定及对材种配置调查分析。采用切片、显微镜拍照、宏观和微观特征分析等方法,对700个试样进行了树种鉴定。结果表明建水指林寺大殿的木构件共有4个树种,分别是硬木松(Pinus sp.)、白青冈(Cyclobalanopsis sp.)、格木(Erythrophleum sp.)和荷木(Schima sp.)。通过材种配置分析可得指林寺大殿木构件在选材方面达到很高水平,不仅反应了建造年代,而且体现修缮的特性。  相似文献

Addressing the recent call to rethink history as a form of presence, the essay works toward a recovery of a space in which such presence of history is encoded. I argue that history as a form of active perception is akin to virtual witnessing of the past in the moment of our encounter with historical artifacts, be they texts, photographs, or buildings. To this end, I engage with the conceptual and material aspects of historical perception, deriving a model of history as “inhabited ruins,” the way it emerges together with historical consciousness and finds an especially dynamic expression in Georg Simmel's philosophy of culture. Throughout, I work with the notion of distance and trans‐dimensional presence as the forces that shape and reshape historical awareness. Ruins, intimately connected to the modern historical imagination, are approached not as sites of commemoration or nostalgia, but as spaces of active exchange between presence and disappearance. As such, they are taken to be the models for the transitive character of history itself, blurring the division between perception and thought. In other words, ruins are taken as structures that evoke and summon the past to an encounter with contemporary reality—a type of co‐appearance that opens the possibility of virtually witnessing the past. I conclude that the logic of “inhabited ruins” constitutes the event‐horizon of modern identity, always placing history right at the threshold of fragmentation.  相似文献

In 1503, the canons of Ripon Minster initiated a building campaign to replace the church’s nave. Through a careful study of the documentary evidence, including sources that have not previously been considered, this article investigates how Ripon’s clergy organised and funded the project. It offers a more precise chronology of the works and an assessment of their impact on the use of the church by its parishioners. The article also considers the clergy’s motives for rebuilding, proving that the renovation was not a reaction to the old nave’s deterioration so much as an initiative to create a grander architectural setting for processions and more space for burial within the church.  相似文献

This article considers the regional order-building challenges that Australia presently confronts in the Indian Ocean region (IOR). The author argues that while regional stability within the IOR constitutes an increasingly important Australian security interest, policy makers will struggle to translate the order-building strategies they have previously pursued in East Asia into an Indian Ocean context. In East Asia, Australia has historically pursued a ‘dual track’ order-building strategy centred on its participation in a US-dominated ‘hub and spokes’ alliance system alongside multilateral regional engagement. The absence of an equivalent alliance system or an established tradition of multilateral security diplomacy conversely precludes an extension of this strategy into the IOR. Growing tensions between the USA and China and between China and India, meanwhile, further complicate IOR security dynamics, while underscoring the urgent need for a more coherent approach to regional order-building. With these challenges in mind, the author concludes by proposing a range of bilateral, minilateral and multilateral initiatives that Australia should pursue to stimulate the emergence of a more cooperative IOR security environment.  相似文献

Between 1998 and 1999 three excavation campaigns were undertaken on a shipwreck at the now‐submerged site of the ancient Portus Magnus, off the coast of Alexandria. The site, close to the island of Antirhodos, was identified through geophysical and archaeological surveys carried out by the Institut Européen d’Archéologie Sous‐Marine (IEASM), directed by Franck Goddio. The remains of the ship lie c.5 m deep and are spread over c.350 sqm. No cargo has been found. Artefacts recovered, the details of the ship's architecture and radiocarbon dating all suggest it sunk between the end of the 1st century BCE and the 1st century CE. Its dimensions correspond to those of commercial ships of the Roman era. Identification of the wood used contributes significantly to our knowledge of materials used in naval architecture of this period.  相似文献

In the conservation of built heritage, earthen ruins rank as one of, if not the most, intractable of problems to be confronted. Lacking the very architectural devices originally in place to combat and control weathering, earthen ruins face rapid deterioration without constant remedial and preventive conservation. Often it is the enormous mass of many ancient earthen ruins that explain their persistence; however, even these will collapse over time from differential erosion, or eventually stabilize as formless lumps. The impossible demands of simultaneously preserving architectural form and fabric (materiality) challenge the archaeologist and conservation professional who attempt to manage both for temporary and permanent display.  相似文献

During the eighteenth and nineteenth centuries, thousands of Scottish emigrants travelled to Canada. This paper concerns those buildings that were designed and constructed by Scottish settlers, utilising skills and materials transported from their homeland. The research concerns the extent to which buildings of those early generations of settler might still be intact, with specific reference to selected case studies from Nova Scotia. One is faced with still intact examples of Scottish architectural heritage, located thousands of miles from Scotland. This has interesting and important implications for the manner in which we value, care for and understand meaning within the built heritage.  相似文献

Abstract

Over the last few decades, conservation work has been conducted by the Department of Antiquities of Jordan (DoA) on the Roman Nymphaeum in Amman. This intervention has taken the form of direct and indirect actions. In this article it will be shown that the conservation works concentrated on reinforcing the structure and reconstructing some architectural features of the building, with little consideration of the techniques and materials used. Intervention actions were mostly poor in terms of their scientific approach, and neither proper planning nor a well-defined methodology existed. This study provides a holistic approach for the evaluation of the state of the conservation of the monument in terms of quality and quantity. Thus, the results could be a valuable source for establishing comprehensive risk mitigation for future restoration work and site management. In addition, establishing practical restoration guidelines could help in developing socio-economic benefits for the community through tourism.  相似文献

西部地区农户经济的空间差异及其发展对策   总被引:2,自引:0,他引:2  
范建刚 《人文地理》2002,17(3):63-65
西部不同地带生态条件的优劣差异决定了西部地区农户经济的空间差异,劣等、中等、优等三类生态条件相应地发育出贫困、温饱、富裕三类群落的农户经济。西部各类农户经济的发展有着不同困难,贫困群落农户脱贫面临人口压力大与生态环境脆弱矛盾突出,及农户人均财政负担重,财政支农能力差的困难,已得温饱的农户面临收入与文化素质低、可带动农户从事产业化经营的企业少的困难,富裕农户面临生产要素流失严重,制度创新滞后的困难。由政府主导,以多种手段、方式带动贫困农户脱贫致富;扶持建立农业合作经营组织,促进已得温饱农户发展农业产业化经营;以制度创新推动富裕农户经济的进一步发展,是应采取的针对性对策。  相似文献

经济地理学中的农户研究   总被引:31,自引:4,他引:31  
中国目前约有2/3的人口生活在农村,农村地区的发展成为中国区域发展中令人关注的大问题。然而,经济地理学在农区发展的研究中,存在一个明显的缺陷,既大多数研究均忽视了农区经济中最基本的单位-农户。文章分析了忽视农户对地理学研究的局限,论述了农户与农区的关系,评述了国内外的相关研究成果,提出在经济地理学的农户研究中,应加强农户发展环境研究、基于农户的农区发展模型研究、农户与地理环境相互作用研究、基于农户的农区发展战略研究。  相似文献
