GIS技术在萨拉乌苏考古遗址公园规划设计中的应用

传统规划设计工作的技术平台多以计算机辅助设计(CAD)为主,本工作以内蒙古自治区鄂尔多斯萨拉乌苏考古遗址公园规划为例,将Arc GIS Desktop作为技术平台应用到公园的规划设计工作中。首先,通过对规划区的实地踏勘,采集相关数据和资料,进行规划区数据库建设;其次,在数据库建设的基础上,通过GIS技术构建与现实环境对应的虚拟地理信息空间,实现规划区景观的三维可视化;最后,利用三维景观模型对现实地理环境进行模拟、分析及虚拟场景飞行。不同于传统CAD的二维工作平台,本工作借助GIS对空间数据和属性数据的强大处理功能及其三维景观可视化模块,为实现内蒙古鄂尔多斯萨拉乌苏考古遗址公园的科学规划提供辅助。     

Use of ground penetrating radar to map subsurface archaeological features in an urban area

The ground penetrating radar (GPR) technique was used to investigate the subsurface in an urban area located in Mesagne (Italy) to obtain a map of the archaeological features in the ground. The GPR survey was undertaken at selected locations placed near (about 50 m) to a necropolis dating from the Messapian to the Roman imperial age, using a GSSI Sir System 2 incorporating 200 and 500 MHz centre frequency antennae. The selected areas (A and B) were surveyed along parallel 1 m spaced profiles using a 200 MHz antenna in area A and along parallel 0.5 m spaced profiles using a 500 MHz antenna in area B. For the selected areas the processed data were visualised in 3D space not only by means of the standard time slice technique, but also by means of a recently proposed approach, namely by iso-amplitude surfaces of the complex trace amplitude. The immediacy in revealing the spatial positioning of highly reflecting bodies, such as the anomaly interpreted as an old hypogeum room in area A, makes 3D visualisation techniques very attractive in archaeological applications of GPR. Their sensitivity to the signal/noise ratio is, on the other hand, highlighted by the quite poor performance in area B, where the only reliable result provided by all the techniques was the ancient living surface reflection, whereas none of them could effectively enhance the visibility of weak hyperbola reflections noted on 2D sections and probably related to the walls located on the ancient living surface. The performance of the various techniques in these two different situations allowed insights into their main advantages and drawbacks to be gained.     

Applying dynamics and comparing life tables for Pleistocene Equidae in anthropic (Bau de l'Aubesier,Combe-Grenal) and carnivore (Fouvent) contexts with modern feral horse populations (Akagera,Pryor Mountain)

In this study, we propose a method based on life tables currently used in population dynamics and ecology to compare the mortality curves of Equidae from anthropic and carnivore fossil assemblages with those from modern populations. The combined analysis of frequency (f_x) with various ecological parameters such as mortality rate (q_x), survival rate (l_x), fecundity rate (m_x), and killing factor (k_x), established for each age class, allows us to characterize the stability of fossil populations. These ecological parameters, developed in demography, correspond to many curves and constitute a complementary approach to interpret the two main mortality models, attritional and catastrophic, often evoked in zooarchaeology. The age structures of fossil horses from the anthropic sites of Bau de l'Aubesier (Vaucluse, France) and Combe-Grenal (Dordogne, France) and the hyena den of Fouvent (Haute-Saône, France) are compared to typical catastrophic modern populations of Equidae from the National Park of Akagera (Rwanda). We also used data collected by the Bureau of Land Management for present day feral horses from Pryor Mountain (Montana, USA) which constitutes a reliable referential of a stable living population. The characterization of age structures in those different contexts is discussed as well as the impact of Neanderthals and hyenas on fossil assemblages.     

Holocene climatic change and past Irish societal response

The extent to which North Atlantic Holocene climatic perturbations influenced past human societies is an area of considerable uncertainty and fierce debate. Ireland is ideally placed to help resolve this issue, being occupied for over 9000 yr and located on the eastern Atlantic seaboard, a region dominated by westerly airflow. Irish bog and lake tree populations provide unambiguous evidence of major shifts in surface moisture through the Holocene similar to cycles recorded in the marine realm of the North Atlantic, indicating significant changes in the latitude and intensity of zonal atmospheric circulation across the region. To test for human response to these cycles we summed the probabilities of 465 radiocarbon ages obtained from Irish archaeological contexts and observe enhanced archaeological visibility during periods of sustained wet conditions. These results suggest either increasing density of human populations in key, often defensive locations, and/or the development of subsistence strategies to overcome changing conditions, the latter recently proposed as a significant factor in avoiding societal collapse. Regardless, we demonstrate environmental change is a significantly more important factor in influencing human activity in the landscape than has hitherto been acknowledged.     

关于“夜郎文化”的思考

本文通过对被认为属于"夜郎文化"的威宁中水、赫章可乐、普安铜鼓山等遗址和墓地的出土遗物的对比研究,指出过去所认定的"夜郎文化"实际上是包含了三种不同的青铜时代文化类型,由此得出的"夜郎文化"并非严格上的考古学文化,而仅是一个大杂烩。     

谈谈考古遗址的展示保护

本文讨论了考古遗址的风化状况和原因,指出考古遗址的破坏是多种因素共同作用而产生的,为了保护考古遗址,就要采用多种相应的技术措施。这些措施包括:保护房的建设、地下水的治理、土体的机械和化学加固及生物因素的控制等。在遗址保护中要根据实际情况选择保护手段。     

思想是考古学的工具--论俞伟超的考古学理论与实践

俞伟超考古学思想历程可以分为三个阶段,马克思主义考古学解释体系的初步探索;考古学文化与族群关系的文献与实物的二重证据推定;考古学文化遗存的技术、社会和观念的三重解读以及以此为方法论核心的考古学新体系的建立。

The Archaeology of Regions: From Discrete Analytical Toolkit to Ubiquitous Spatial Perspective

In the 1970s and 1980s, regional analysis was an influential part of archaeological research, providing a discrete set of geographical tools inspired by a processual epistemological and interpretive perspective. With the advent of new technologies, new methods, and new paradigms, archaeological research on regional space has undergone significant changes. This article reviews the state of regional archaeology, beginning with a consideration of its history and a discussion of the fundamental issues facing regional investigations before focusing on developments over the last several years. On one hand, the diversification of archaeological theory has created new paradigms for thinking about human relationships with one another and with the physical environment across regional space; in this regard, historical ecology, landscape archaeology, and evolutionary theory have been particularly influential in recent years. This has led to a corresponding diversification of the traditional methods of regional analysis. Most notably, the advent of powerful digital technologies has introduced new tools, especially those from the geographic information sciences, that build on the quantitative methods of past approaches. The investigation of regional data is no longer based on a discrete toolkit of simple mathematical and graphical procedures for representing spatial relationships. Instead, regional archaeology has matured into a diversity of multiscalar spatial and geostatistical techniques that inform many areas of archaeological inquiry.
