This paper is focused on the joint use of non‐invasive and minimal intervention techniques for supporting archaeological prospection. Very high resolution (VHR) satellite imagery analysis and ground‐penetrating radar (GPR) and boring surveys were integrated for the study of the Longcheng site, located near Hefei city in Anhui Province, China, to test their effectiveness and efficiency in prospecting archaeological remains and evaluating their degree of preservation. First, target locations of potential archaeological structures were identified on a WorldView‐2 (WV‐2) satellite image through spatial and radiometric enhancement, interpretation and object‐oriented classification. Second, archaeological features extracted from the WV‐2 imagery were further investigated by a GPR survey that provided detailed cross‐checking information about buried remains. Finally, a subsequent boring survey was conducted across those prospective archaeological structures in order to map the stratigraphic sequences on the basis of colour, compactness and the inclusions contained in the soil, and then to test their correspondence with the GPR data. The boring led to detailed confirmation of the results produced by the remote sensing analyses and GPR surveys, as well as the discovery of datable artefacts. On the basis of all the integrated data, the preliminary layout and structure of the Longcheng site was reconstructed in GIS. Furthermore, the widths, lengths, heights and burial depths of these buried archaeological structures were estimated in detail.  相似文献

Rich settlement and burial evidence from the Baikal/Angara region in Central Siberia provides one of the most promising opportunities in the global boreal forest for studying Holocene foragers. The Neolithic and Early Bronze Age prehistory of the region is known to western scholars only through a few English translations of the works of A. P. Okladnikov. Since the publication of Okladnikov's model, the region has witnessed large-scale archaeological fieldwork that has produced abundant quantities of new evidence. Moreover, the model has been partly invalidated by extensive radiocarbon dating. Research advances over the last couple of decades have augmented the area's previous reputation but have also revealed the need for new theoretical perspectives and modern analytical techniques.  相似文献

湖滩争夺与省界成型——以皖北青冢湖为例   总被引:1,自引:0,他引:1  
在传统地方史志的记载中,对于一个行政区疆域的记载往往是以"四至八到"的形式来表示的,依照这种粗略的记载,在很多地区根本无法准确的划出政区之间的边界。在各级政区的边界类型中,又属省界的地位比较特殊。对于省界争端的处理往往会面临"属人主义"和"属地主义"两种原则的抉择,而争端的处理过程其实体现了中央政府、省政府、基层政府与普通民众之间的多重复杂、互动的关系。民国时期青冢湖苏皖省界纠纷的处理过程正是体现了上述关系,并且展现了原本模糊的省级政区界限逐渐演变为精确的几何界线的动态过程。  相似文献

杭州在唐宋时期的辉煌历史与灿烂文化,是明末清初西湖小说的素材来源与情感寄托,而这在与后南宋时代的兴衰对比中产生了强烈的反差与失衡。失落中的梦华怀旧情结,在小说作者的审美心理与创作动机中,以及杭州读者群的接受心境与审美情趣中是普遍存在的。这是明末清初西湖小说兴盛的一个重要心理因素。  相似文献

Paleodiet reconstruction using stable isotopes of carbon and nitrogen was carried out on individuals from the Bronze Age cemetery, Khuzhir-Nuge XIV on the western shore of Lake Baikal, Russian Federation. The cemetery contained 79 graves with 89 individuals and was in use between approximately 2700 and 2000 cal. B.C. with the exception of one burial, dated to around 4000 B.C. Archaeological and ethnographic evidence indicates that hunting and fishing were the main subsistence activities while gathering was less important. δ13C from collagen and carbonate apatite was analysed, along with δ15N from collagen. Bone mineral preservation was evaluated using Fourier transform infrared spectroscopy. δ13C and δ15N of collagen are positively correlated and reflect varying reliance on terrestrial mammals, fish, and seals from Lake Baikal. Lake Baikal biota exhibit considerable variation in δ13C at the base of the food web thus; there is variation in human δ13C (−20.1‰ to −16.2‰) despite the fact that there are no C4 plants in the region. δ15N results (range 10.3‰–16.5‰) indicate that fish, and possibly seals, made up some of the diet for everyone, but in varying amounts relative to terrestrial herbivores. δ13C from carbonate is not correlated with δ13C from collagen, a situation that has been found in remains from other coastal sites. A mixed diet from both terrestrial and freshwater ecosystems is the most likely explanation. Analysis of mortuary variables within the cemetery reveals three distinct clusters of graves with variations in burial treatment among the clusters. δ15N values are significantly different among these clusters, suggesting an association between diet and mortuary customs.  相似文献

A number of archaeological sites on Lake Baikal revealed evidence of Neolithic and Bronze Age seal hunting. A collection of 35 canines from four sites was used to develop a methodology for analysing growth increments of canine dentine for the purpose of examining aspects of prehistoric seal hunting. Results from this preliminary analysis indicate that seal hunting at these sites was a seasonal activity confined to spring and early summer. Baikal seals were probably hunted in early spring for their meat, blubber and furs, and later in the season for their meat and skins.  相似文献

Abstract

In situ preservation is a core strategy for the conservation and management of waterlogged remains at wetland sites. Inorganic and organic remains can, however, quickly become degraded, or lost entirely, as a result of chemical or hydrological changes. Monitoring is therefore crucial in identifying baseline data for a site, the extent of spatial and or temporal variability, and in evaluating the potential impacts of these variables on current and future in situ preservation potential.

Since August 2009, monthly monitoring has taken place at the internationally important Iron Age site of Glastonbury Lake Village in the Somerset Levels, UK. A spatial, stratigraphic, and analytical approach to the analysis of sediment horizons and monitoring of groundwater chemistry, redox potential, water table depth and soil moisture (using TDR) was used to characterize the site.

Significant spatial and temporal variability has been identified, with results from water-table monitoring and some initial chemical analysis from Glastonbury presented here. It appears that during dry periods parts of this site are at risk from desiccation. Analysis of the chemical data, in addition to integrating the results from the other parameters, is ongoing, with the aim of clarifying the risk to the entire site.  相似文献

Abstract

This paper aims to analyse the collaboration of the Greek-Albanian Archaeological Expedition with the local community of the tri-national district (FYROM-Greece-Albania) of the Great Prespa Lake, in South-eastern Albania, conducted by the Institute for the Transbalkanic Cultural Cooperation (Greece) and the Institute of Archaeology of Tirana (Albania). It is argued that local cultural heritage, including the heritage of the archaeological past, can play a significant reconciliatory role in an extremely delicate national and environmental landscape throughout the work of all the bipolar participants: locals and ‘foreign experts’.  相似文献
