基于形态学的历史性城镇景观遗产价值判识与地理过程分析——以庐山牯岭镇为例

当今我国历史性城镇景观的研究、保护与管理多基于历史遗存的现状展开,对其价值认知和保护管理造成了一定的不利影响。城市形态学领域的康泽恩学派根植于城镇的历史演化过程,为历史性城镇景观的认知及保护管理提供了良好的支持。在该理论的指导下,对庐山牯岭镇开展了遗产价值判识与地理过程分析,其间,根据中国的历史文化和社会经济背景,对该方法进行了调整与发展,旨在探讨适合中国历史性城镇景观的保护管理及更为广泛的城镇景观的管理方法。     

Relationships of tristichopterids (osteolepiform lobe-finned fishes) from the Middle–Late Devonian of East Gondwana

Wang, Z-B., Gao, J-H., Wang, G-H. &; Kang, Z-H., June 2018.2018. Foraminiferal biostratigraphy and facies analysis of the Permian Longge Formation in the Rongma Area, Tibet, China: implications for the palaeogeography of the South Qiangtang Block. Alcheringa XX, x–x.

The Permian Longge Formation in the South Qiangtang Block, Tibet, is overwhelmingly composed of carbonate rocks with various skeletal (brachiopods, foraminifers, gastropods, echinoderms, ostracods, corals, bivalves, algae, and bryozoans) and non-skeletal (intraclasts and ooids) components. Three stratigraphic sections of the Longge Formation in the Rongma area of north-central Tibet—known as South Yibug Caka, Niushan and East Yibug Caka—were selected for this study, which examined both sedimentary facies and foraminiferal assemblages. The foraminifers in these sections consist of at least 38 species belonging to 18 genera. Based on the distribution of the foraminifers throughout the composite section, two foraminiferal assemblages were established, and the age of the Longge Formation was determined to be late Kungurian to Capitanian. During lithological studies, ten microfacies were identified using depositional textures, petrographic analysis and faunal content: mudstone, bioclast wackestone, bioclast perforated-foraminifera packstone, bioclast crinoid grainstone, intraclast wackestone, breccia, intraclast grainstone, ooid grainstone, fine crystalline dolostone and residual-grain dolostone. These microfacies are interpreted to represent four depositional environments—restricted lagoon, open marine, shoal and slope—which together suggest a shoal-rimmed carbonate platform. The non-fusuline foraminifers show transitional palaeobiogeographic affinities (Tethyan Cimmerian subregion), and the assemblage is considered to be influenced by the northward drift of the South Qiangtang Block, the climatic warming after the Late Paleozoic Ice Age and warm-water oceanic currents caused by the newly formed Neotethys Ocean. This indicates that the South Qiangtang Block was located in a relatively warm-water, low-latitude area during the middle Permian. The Permian depositional sequences in the Rongma area were also influenced by the palaeogeographic evolution of the South Qiangtang Block.

The Library is on Fire,Now What? Assessing the Damage and How to Approach It: A Case Study from the Chesapeake Bay

ABSTRACT

The Longwood Institute of Archaeology conducted the Vulnerability, Potential and Condition (VPC) assessment of shoreline archaeological sites along 1990 km (1237 miles) of the Chesapeake Bay in Virginia. VPC assessment involves a three-pronged approach that includes (1) the assessment of site vulnerability due to changing shorelines using an analytical package called Analysing Moving Boundaries Using R – AMBUR, (2) the assessment of potential shoreline site locations through predictive modelling using Weights of Evidence – WofE – analysis, and (3) the assessment of current conditions of known sites through direct observation. Vulnerability assessment results indicated that 49% of site shorelines in the project area are moving landward. Potential assessment located high-probability site locations with an 83% efficiency. Condition assessment, conducted using standard field protocols, provided feedback of the sites’ current conditions. The intended outcome of this method is to provide resource managers with information needed to make informed, data-driven management decisions.     

中国古代文明和国家起源研究中的几个问题

近年来新出土的《容成氏》等战国竹书,在增加和扩充史料的同时,我们也应意识到它们依然是有其局限性的,重建上古史还得靠以考古学为基础的多学科的结合。而考古学本身也有自己的局限性,它也需要借鉴人类学的理论以及技术的、经济的、环境的、人口学的等等知识。将酋邦理论、社会分层理论与聚落形态学理论相结合是研究的趋势和方向,但理论贵在创新。因而,结合中国考古新发现,从中国的材料出发,创建出符合中国历史实际的理论,才是最上乘的文明和国家起源研究。依据近年来对山西襄汾陶寺和河南新密古城寨的考古发现,将早期文明与初始国家出现的时间,划定在龙山文化时代,应该说是有着充分事实依据的。与此相关,将中国古代的国家形态划分为邦国—王国—帝国,要比称之为古国—方国—帝国,更约定俗成更合理一些。     

The dental arcade and human morphology

Cranio-dental fossils are relatively common in the fossil record and this paper considers the question of whether the dental arcade can act as a predictor of hominid morphology. A method of measuring the catenary number of an arcade is also described and defined. © 1998 John Wiley & Sons, Ltd.     

Cities of God? Medieval urban forms and their Christian symbolism

Situated in the context of recent geographical engagements with 'landscape', this paper combines 'morphological' and 'iconographic' landscape interpretations to examine how urban forms were perceived in late medieval Europe. To date, morphological studies have mapped the medieval city either by classifying urban layouts according to particular types, or by analysing plan forms of particular towns and cities to reveal their spatial evolution. This paper outlines a third way, an 'iconographic' approach, which shows how urban forms in the Middle Ages conveyed Christian symbolism. Three such 'mappings' explore this thesis: the first uses textual and visual representations which show that the city was understood as a scaled-down world – a microcosm – linking city and cosmos in the medieval mind; the second 'mapping' develops this theme further and suggests that urban landscapes were inscribed with symbolic form through their layout on the ground; while the third looks at how Christian symbolism of urban forms was performed through the urban landscape in perennial religious processions. Each of these 'mappings' points to the symbolic, mystical significance urban form had in the Middle Ages, based on religious faith, and they thus offer a deepened appreciation of how urban landscapes were represented, constructed and experienced at the time.     

Why Do Languages Lose Grammatical Categories?: Latin and Romance Evidence

Although sound change may contribute to the loss of grammatical categories, such as the Latin future and passive, comparative data show that phonological change alone cannot account for these morphological changes. Syncretism can arise from sound change, but patterns of sound change within Romance falsify the homonymy avoidance argument. Furthermore, Italian and Occitan provide models for analogical \"solutions\" to syncretism. Patterns of loss of grammatical categories must be contextualized cross-linguistically without preconceptions about which categories may be lost. Close analysis of phonological and morphological factors will facilitate the establishment of a typology of category loss.
