从三峡地区与东部平原的对比看考古学文化中的环境因素

三峡地区与东部平原的不同地理环境,导致了峡区和平原地区的考古学文化的差异。古代人类对不同地理环境适应的结果,是反映在考古学文化中的环境因素。     

集体化时期农村人口流动剖析--以赣闽粤边区为例

学界一般认为,在长达20多年的集体化时期,农村人口难以流动,农村社会几乎是一个不流动的社会.通过对赣闽粤边区农村人口流动剖析后发现:集体化时期,农村社会仍然流淌着人口流动的涓涓细流;这些细流,既有城镇人口的下乡流,也有农村劳力的进城流,还有农村内部的人口迁移流.集体化时期很大程度上是一个由体制安排移民的时代;集体化时期的农村社会,很大程度上是一个人口向农村、向山区迁流的社会.     

Variabilité et fréquence des cycles de gel‐dégel dans la région de Québec, 1977–2006

Freeze‐thaw cycles are most common at the beginning or near the end of the winter season. These cycles have various effects on the ecosystems of Eastern Canada, affecting both biotic and abiotic components of temperate cold environments. Using air temperature minima and maxima from four meteorological stations close to Québec City, we determined the frequency of daily freeze‐thaw cycles for the last 30 years. The results show no significant increase in the number of freeze‐thaw cycles despite a small increase in air temperature. Polynomial curves describing the relationship between mean air temperatures and the number of freeze‐thaw cycles were calculated. Based on these equations and anticipating a climate change scenario, we projected future freeze‐thaw cycles. Assuming a 5 °C increase in mean air temperatures by 2100, we estimated that the number of days with a freeze‐thaw cycle could increase by approximately 20 days per winter. The increase in the number of such cycles will be concentrated during the coldest months of the winter (January and February).     

丝绸之路沿线城镇空间分布特征研究

丝绸之路是一条连接欧亚大陆的著名古代陆上商贸通道,沿线分布有众多的城镇。通过实地调研和文献分析,结合立地条件对丝绸之路沿线城镇空间分布的地域特征进行了系统分析,依据城镇发展阶段的不同,提出了散点型、串珠型和网络型三种基本的空间分布形态,在分析研究政治、经济、环境、文化等要素的时空组合基础上,提出了城镇空间演变的三个基本特征,即空间发展的差异性,中心城镇的游移性和城址变迁的宜居性,这对于指导丝绸之路沿线城镇化发展和新农村建设具有十分重要的意义。     

The reconstruction of past environments through small mammals: from the Mousterian to the Bronze Age in El Mirón Cave (Cantabria,Spain)

El Mirón is a large cave in the Cantabrian Cordillera of northern Spain that presents a long archaeostratigraphic sequence radiocarbon-dated by over 60 assays to between 41,000 and 2000 BP. The sediments, collected from four areas within the cave and sieved-washed with fine wire meshes, contain microvertebrate remains of fish, frogs, lizards, birds and mammals, of which the latter are most abundant. Preliminary taphonomic analysis suggests that the microvertebrates were naturally collected by owls and (less) small carnivores. Small mammal assemblages are useful for palaeoenvironmental reconstruction because they are linked to particular habitats and are sensitive to environmental changes. The small mammals from El Mirón are ideal for this because sample sizes are large, bone preservation is good, and the stratigraphic sequence is long. In this paper we reconstruct the late Quaternary environments in the Cantabrian region of Spain using small-mammal assemblages from El Mirón Cave. On the basis of the ecologic adaptations of this suite of fauna, the majority still extant, we have identified seven habitat types, which are plotted through time. The evolution of the small mammal assemblages at El Mirón reveals seven major climatic shifts that correspond closely to the climatic changes recognized in the Iberian Peninsula during the last 41 kyr.

谈肩水金关汉简中的几个地名

新近公布的肩水金关汉简记录有丰富的西汉行政区划信息。本文结合传世文献,对汉简所见赵国尉文、梁国載、魏郡鄃、魏郡厝、魏郡廪丘等地名以及相关西汉政区问题进行分析。本文指出赵国尉文县与尉文侯国有关,梁国載县为《汉书·地理志》梁国甾县的早期书写形式,鄃、厝两县于武帝末年至元帝初年隶属魏郡管辖,而简文中的"魏郡廪丘"则为魏郡斥丘的误释。     

王油坊类型龙山文化南徙路线重建——兼论江淮地区的“廊道”性

王油坊类型龙山文化的南徙之旅呈现东西两途。西线去往宁镇地区,即禹会-牛头岗-江宁点将台和高淳朝墩头;东线前赴环太湖流域,即禹会-南荡,至江阴花山,再东去松江广福林。在其南徙的过程中,江淮是必经之道。江淮属于"廊道"地区,一方面,它的连通性给区域间文化交流带来便利;另一方面,这一开放的区域又易引来外域强势文化的干扰,导致本地文化受损。众多的能流、物质流、信息流,都以高密度、高流速和少停留的方式从此通过,从根本上决定了廊道地区相比于稳定的文化母区,不可能凝聚和沉淀起深厚的文化底蕴,导致江淮地区的社会进程出现断裂相。     

新石器时代中国玉器的区域特征

新石器时代我国辽河流域、黄河流域与长江流域三个地区的玉器,在材质、造型和纹饰方面表现出强烈的区域性特征:辽河流域的玉器多采用岫岩玉为原料,长江流域的玉器则多用透闪石一阳起石制成,而黄河流域多见绿松石制成的器物;辽河流域的玉器纹饰简单风格朴实,长江流域的玉器器形和纹饰都很特别,黄河流域则多生产工具且光素无纹.此外,玉器反映了新石器时代中晚期辽河流域内渔猎经济和宗教在社会中居于主导地位,长江流域中下游地区则可能进入了王权、军权和神权一体化的方国阶段,而世俗权力的独大在黄河流域普遍存在.世俗权力在这一地区社会政治生活中占据了主导地位.     

试析河南汉墓出土陶仓楼的分期及区域特征

本文在陶仓楼类型划分基础上,认为河南汉墓出土的陶仓楼至西汉晚期在豫中地区首先出现,为二层带腰檐建筑.西汉末至东汉早期此型陶仓楼向高层发展,区域由豫中扩展到豫北地区.东汉早期豫西、豫西南地区出现二层无腰檐陶仓楼.这时期河南陶仓楼数量和式样增多,分布范围广泛.东汉中期为陶仓楼繁荣期,豫北地区出现带附楼的院落式陶仓楼.东汉晚期各区域陶仓楼走向衰落.
