吴哥遗址保护行动中展现出来的多国合作模式和跨学科综合性的保护和发展方法,使其成为全球范围内文化遗产保护的典范。柬埔寨的吴哥遗址举世闻名,但由于疏于保护,它于1992年被世界遗产委员会以濒危遗产的形式列入世界遗产名录。次年,联合国教科文组织(以下简称UNESCO)出面,由法国和日本牵头,组织国际上多个国家和国际组织发起拯救吴哥保护行动,并成立了吴哥古迹国际保护与发展协调委员会(简称ICC),从而 相似文献

An Evolutionary New Economic Geography Model 总被引:3,自引:0,他引:3
In this paper we present a general new economic geography model with multiple industries and regions, full labor and capital mobility, land use in production and consumption, and a dynamic adjustment process in which consumers maximize utility and firms respond to nonzero profits. All industries use intermediate inputs as well as land, labor, and capital. Systems of cities form endogenously within this framework, including asymmetrical urban hierarchies and cities of different sizes and industry compositions. Each urban area has a bid-rent gradient and zones with land uses and densities as in the von Thünen model. The equilibrium depends not only on initial conditions but also on speeds of adjustment. The model is a prototype for empirical implementation, as illustrated with a simulation of the effects of transportation cost reductions. 相似文献

This paper examines successful policy network (henceforth PN) practices in the Basque Country over an 18-year period, in relation to Cluster Associations, Quality Promotion and Local Agenda 21 Promotion. Basing our work on the Basque experience and on previous multi-disciplinary knowledge regarding learning processes, networking management and marketing, we contribute new insights that help to understand how PN management evolves. The need to analyse PN from an evolutionary perspective has been pinpointed by the various traditions of network research as one of the main gaps in the study of networking. Our research shows that expertise in PN management is generated through a long, performance-oriented dilemma-solving process that takes place in time and space. The first experiences provide initial knowledge and absorptive capacity, both of which improve through new and diverse experiences of increasing complexity. Step by step, a quantity of tacit and codified knowledge is created and shared, mainly through face-to-face contact, within the territory. Finally, the knowledge achieved is substantially similar to the normative knowledge that, though sparse, can be found in various networking literatures and needs to be brought together. But we also suggest that more emphasis on PN marketing is needed. 相似文献

This paper describes an algorithm for spatial search, which is used in an expert system for site selection. The algorithm, named ProfMat, is able to find the best site in the area of interest even when the number of possible sites is large and many decision criteria are involved. Compared to commonly used search procedures, ProfMat improves the efficiency of spatial search in two ways. First, the best site is identified through an iterative rather than a linear process of selection and evaluation of optional sites. Second, an area is searched by narrowing down the focus to increasingly smaller areas and, thus, sites are evaluated as much as possible groupwise. The ProfMat procedure is illustrated by analyzing the problem of retail site selection. A comparison with alternative search procedures shows that ProfMat considerably reduces the evaluation costs needed to find the best site. The implementation of the algorithm in an expert system shows how ProfMat can be used in combination with specialist's knowledge to solve site-selection problems. The efficiency of the procedure allows considering large sets of optional sites, so that it may improve the quality of the outcome. 相似文献

赤峰东山嘴遗址属于夏家店下层早期。该遗址简报有目前这一文化唯一的遗址平面图。从图中我们可以看出两类灰坑:一种是距房址很近的规整的深坑;另一种是距房址较远的不规则浅坑。前者主要出土陶器与农具;后者多出与手工业相关的器物,其中骨针多为完好的。简报认为前者是窖穴,后者是垃圾坑。我们认为前者应为窖穴,但后者应是从事家庭手工业的场所,这里地穴式房址采光极差也可以印证这个推论。通过对另外十几个夏家店下层文化的遗址房屋出土物的分析也发现有农具集中和非农具集中的两类房屋。这种现象还有待更多的资料来证实和解释。 相似文献

This article presents a discussion of recent advances in underwater photogrammetric survey, illustrated by case studies in Scotland and Denmark between 2011 and 2013. Results from field trials are discussed with the aim of illustrating practical low-cost solutions for recording underwater archaeological sites in 3D using photogrammetry and using this data to offer enhanced recording, interpretation and analysis. We argue that the availability of integrated multi-image photogrammetry software, highly light-sensitive digital sensors and wide-aperture compact cameras, now allow for simple work flows with minimal equipment and excellent natural colour images even at depths of up to 30 m. This has changed the possibilities for underwater photogrammetric recording, which can now be done on a small scale, through the use of a single camera and automated work flow. The intention of this paper is to demonstrate the quality and versatility of the ‘one camera/ambient light/integrated software’ technique through the case studies presented and the results derived from this process. We also demonstrate how the 3D data generated can be subjected to surface analysis techniques to enhance detail and to generate data-driven fly-throughs and reconstructions, opening the door to new avenues of engagement with both specialists and the wider public. 相似文献

2003~2004年对安图县仲坪遗址进行了抢救性发掘,发现青铜时代和渤海时期两个时代的遗存.从青铜时代瓮棺墓的结构及出土的石器、陶器的器形看,均与图们江流域青铜时代距今3000~2500年的同期遗迹、遗物形制一致,应属同一文化类型.发掘的11座渤海时期的土圹石椁墓的结构及出土的陶器、铜器、铁器的形制与渤海中期的同类遗迹、遗物相近,应为渤海中期左右的墓葬. 相似文献

宝塔河遗址出土的东周时期遗迹有灰坑、陶窑和墓葬,遗物仅见陶器与石器,器类包括鼎、釜、罐、鬲、盂、豆等。这些遗存分三期,时代跨度从春秋早期至战国早期。内涵分为两组,一组以鼎、釜、罐为核心,代表着峡江地区一支传统的鼎釜文化;一组以鬲、盂、豆为核心,为楚文化。春秋早期以传统鼎釜文化为主,春秋中期以后,楚文化逐渐介入,春秋晚期以后,楚文化在这一地区已成为主导文化。这一过程为我们研究峡江地区传统文化的发展脉络,楚文化的扩展趋势,提供了重要的实物证据。 相似文献
