The flora of the archaeological area of Maxentius’s villa (Rome) was tested as bioindicator of buried remains of masonry and pavements. A total of 53 floristic surveys provided the occurrence of each species in sample units, as well as some their phenological features. The data were elaborated through multivariate statistical analysis in order to assess floristic affinities/differences among sample units, and define their ecological characteristics. The fuzzy set methodology was applied to evaluate relation between floristic richness, plant cover and soil depth. Results showed that the buried remains of stonework create a discontinuity in the ground, influencing the flora growing above it. This phenomenon may give rise to differential presence of some species (e.g., Cota tinctoria, Trifolium scabrum ssp. scabrum on thin soil; Ranunculus bulbosus, Trifolium pratense on deeper soil), but will not have such a great effect on floristic richness. The bioindication of this phenomenon also occurs through phenological irregularities in single specimens and changes in plant cover. Nevertheless other environmental factors (soil moisture/aridity, trampling, enrichment of nitrogen, cutting, ground depression) can interfere with the use of plants as bioindicators of buried structures. It is therefore necessary to consider other factors ecological influencing each site when you want to use plants as bioindicators in archaeological prospection. 相似文献

Launch of Very High Resolution (VHR) satellite sensors meant a significant evolution for Remote Sensing archaeological applications since data with high spatial resolution may be used to identify signals related to buried archaeological remains (e.g. cropmarks, soilmarks, dampmarks) in very extended territories. The aim of this work is to develop a suitable image processing workflow to improve the cropmark visibility in the VHR satellite images. The workflow implemented consists of two steps: first the panchromatic and multispectral images have been pansharpened in order to merge the two images, then some Enhancement methods have been applied on the pansharpened image. As a result of the several tested pansharpening techniques, the Principal Component Resolution Merge yields images of very good quality useful not only for visualization but also as input for further processing. Among the different enhancement methods taken into consideration, the Spatial Enhancement, carried out by applying the Wallis Adaptive filter further improve the visibility and recognition of the archaeological signals. 相似文献

AbstractRecent developments in archaeological research have highlighted the need to build up a Guide to Archaeostratigraphic Classification and Terminology. Its preparation was undertaken by Workshop 2 (“Classification et Terminologie Archéostratigraphiques”) in the context of the International Geological Correlation Programme. The paper below is the first version of this Guide project; it is intended to propose some basic definitions and principles. 相似文献

This paper reports the results of a study into the effectiveness of core sampling for discovering Palaeolithic and Mesolithic hunter-gatherer sites in the Netherlands and northwestern Belgium. Earlier work established optimal sampling strategies for use in archaeological heritage management survey in the Netherlands. However, the statistical model used for this was based on a limited amount of data on the distribution of lithic artefacts in Palaeolithic and Mesolithic sites. For the current study we have analyzed the distribution of artefacts in a selected number of excavated sites, and estimated discovery probabilities of these sites through simulation. The simulation results indicate that discovery probabilities are lower than expected due to the effect of clustering of finds. Furthermore, the density of flints in Palaeolithic and Mesolithic sites is generally lower than the estimates that were used for setting up the optimal sampling strategies, and a substantial number of sites is very small. This means that, in order to discover Palaeolithic and Mesolithic sites with sufficient reliability, we will have to apply more intensive survey strategies than have been recommended up to now. 相似文献

Spatial and temporal variety of prehistoric human settlement and its influencing factors in the upper Yellow River valley,Qinghai Province,China 总被引:4,自引:0,他引:4

We report an investigation of forty-two prehistoric sites in the upper Yellow River valley located in Guide, Jianzha, Hualong, Xunha and Minhe, Qinghai Province, China, including forty-four new radiocarbon dates from twenty-four sites, review published archaeological surveys and radiocarbon dates, analyze landform features and discuss the reasons for spatial and temporal variety of regional prehistoric human settlement. Our results suggest that people occupied the upper Yellow River valley during the early Holocene, but a continuous archaeological record begins only after about 5500 Cal yr BP. Thereafter, the intensity of prehistoric human settlement in the area is varied. Neolithic human settlement spread northwestward to high altitude areas of the upper Yellow River valley during early-mid Majiayao and Qijia periods, but moved southeastward to lower locations in the area during late Majiayao period. During the Bronze period, two coeval archaeological cultures, the Kayue and Xindian, occupied the upper Yellow River Region. Kayue archaeological sites are numerous and widely distributed in the high areas of the upper Yellow River, while Xindian sites are restricted to the lowest basin of the region. Variation in site density and location are likely the result of changing paleoclimate and technology. 相似文献

An integration of geophysical surveys, ground hyperspectral data, aerial photographs and high resolution satellite imagery for supporting archaeological investigations at the multi-component Vészt?-Mágor Tell, located in the southeastern Great Hungarian Plain, is presented in this study. This is one of the first times that all these techniques have been combined and evaluated for retrieving archaeological information. Geophysical explorations, specifically magnetic gradiometry and ground penetrating radar methods, have revealed shallow linear anomalies and curvilinear rings at the Tell. The use of remote sensing images has confirmed the diverse anomalies with respect to geophysics through photointerpretation, radiometric and spatial enhancements. Moreover, several indices from ground hyperspectral data also have revealed stress vegetation anomalies. These integrated results were used to map the main areas of archaeological interest at the Vészt?-Mágor Tell and plan future excavations. It was found that these multiscalar data can be used efficiently for detecting buried archaeological features. 相似文献

When prehistoric archaeological sites yield non-carbonised wood, one of the ways to test for management practices consisting of pollarding and coppicing is analysis of branch diameter and age. However, the interpretation of such data is often based on assumptions. To test whether it is in fact possible to identify past woodland management on the basis of age/diameter analysis in archaeological wood assemblages, this paper presents models that predict the expected age and diameter distribution of branches from unmanaged and managed trees. The models have been tested using data on modern-day Alnus glutinosa, Fraxinus excelsior and species of the genus Salix. Branches of modern-day unmanaged and managed trees with a diameter up to approx. 2 cm (not an absolute limit) have a comparable age. Branches with a diameter of approx. 2–6 cm from unmanaged trees are older than similar branches from managed trees. The age distribution in the latter also ends abruptly. The age/diameter data from the modern-day trees indicate that the models can be used to discern management in the past, if branches up to approx. 2 cm in diameter are avoided and if, critically, taxon, sample size, growing conditions, natural disturbance/opportunistic wood collection and the possibility of diameter selection are taken into account. Archaeological datasets mainly from prehistoric sites are then reinterpreted by means of comparison with the models. Indications of management in prehistory as demonstrated by age/diameter are scarce but available. There is thus a clear need for further research in this field. Practical suggestions are provided for improving the quality of future research on woodland management practices by means of branch age/diameter analysis. 相似文献

On 31 July 1849, John Collingwood Bruce gave a lecture on Hadrian’s Wall at the British Archaeological Association’s annual Congress in Chester. This was his first lecture outside his native North-East on the subject on which he was soon to become the leading authority. Two primary accounts of the occasion survive, but are contradictory in several details. These contradictions are explored, the accuracy of the account in the JBAA upheld and the importance of the occasion emphasised. 相似文献
