The influence of relief, as well as other environmental features such as soils or the hydrological regime, on prehistoric settlement patterns is commonly accepted. Settlement patterns and preferences changed over time in different areas, so it is difficult to formulate general rules of human behaviour throughout history. In lowland areas of the temperate zone, which lack radical relief changes and have widespread access to water resources, specific settlement preferences and significant changes in these preferences are difficult to interpret.New methods developed to address the problem of the settlement transformations as a result of prehistoric settlement and economic processes using multivariate statistics have been adapted for the middle part of the Great Poland Lowland. In this region, data from the Polish Archaeological Record Project database have been used.Models of the dependence between geomorphological features and settlement intensity form the basis for estimating changes in prehistoric settlements. The degree of preference (or avoidance) is a nonparametric function of the number of archaeological sites observed in the area relative to the number of sites expected from a completely random pattern. The most crucial factors for settlement are distance to plateau edges, distance to water bodies, and the wetness index. The results show that the entire investigated area is more or less suitable for settlement, but the most occupied terrains are the areas near plateau edges.  相似文献

Archaeologists generally agree that Paleoindian residential groups moved regularly over extremely large ranges. However, on the Great Plains, this argument depends substantially on datasets derived largely or entirely from projectile points rather than from systematic analysis of a wide range of artifacts. This paper argues that projectile points differ from most Paleoindian tools in ways that make such datasets unlikely to be reliable sources of information on range sizes. Furthermore, evidence from Paleoindian tool caches and the condition of discarded points suggest strongly that the raw material used to produce projectile points at least sometimes moved across the Plains independently of material used to make most other kinds of flaked stone tools. This, in turn, implies that not all stone used during Paleoindian times was procured by visits of whole residential groups to raw material sources, raising serious questions about the validity of widespread views of Paleoindian mobility.  相似文献

鲁北—胶东盐业考古调查记   总被引:1,自引:0,他引:1  
本文通过对鲁北莱州湾和胶东半岛16个县市和出有盔形器的遗址进行了调查,对盔形器的形态演变、分布区域、使用功能等进行了初步研究,并与国内外有关遗址和类似器物作了比较分析,确认菜州湾沿海包含大量盔形器的遗址是商周时期的制盐作坊,而盔形器则是制盐的特殊用具.  相似文献

三衙,全名为殿前都指挥使司、侍卫亲军马军都指挥使司和侍卫亲军步军都指挥使司,是北宋禁、厢诸军常设之统帅机构。其帅,宋人称作“三帅”、“管军臣僚”,或简称“管军”。三衙制度,与募兵制取代征兵制相适应,肇始于唐末五代,至北宋方渐趋于定型。它的确立,首先解决了中唐以降的藩镇割据问题。兵权由地方集中到中央得以实现。在此基础之上,从宋太祖开始的北宋统治,本着“兵权宜分不宜专”的原则,又从合理调整三衙与枢密院、皇城司以及帅臣之间的关系人手,构建了三衙、枢密使、皇城司主管宦官、帅臣之间彼此相互制衡的严密体系,并加强了台谏对三衙的监察,和皇帝对军政的亲自干预,从而进一步实现了兵权向皇帝手中的集中。  相似文献

Abstract

It has recently been proposed that lowered lake levels after 4250 BP broadened opportunities for mobility and interaction patterns among hunter-gatherer populations in the Saginaw drainage and in Michigan more broadly (; ). Here, data are presented on chipped stone reduction strategies as reflected in two site assemblages in Bay City, Michigan (20BY28, 20BY387) that bridge this key point in time. The earliest Late Archaic components of these sites, occupied during the higher than modern post Nipissing recession ca. 3200 BP, are typified by on-site reduction of local cherts, often utilising a bipolar reduction strategy. Subsequent uses of the area largely shifted to lower elevations. The more recent site components contain both more diverse projectile styles, many of which can be linked with Ontario types, and higher occurrences of non-local raw materials, specifically Onondaga chert apparently arriving at the site as preforms. The last use of these sites occurred during the Late Woodland, also during lower water levels approaching modern, and reflecting the highest use of Onondaga chert. We suggest that these changes resulted from shifting mobility and exchange patterns, facilitated in part by lowered post Nipissing water levels.  相似文献

魏晋南北朝时期,在继承秦汉杂述及地理志书的基础上,进入了中国古方志发展史上的一个特殊的繁盛阶段。在国家分裂,朝代更迭的背景下,各种方志层见错出。计有:"记"、"志"、"录"、"传"、"赞"、"图"等多种体例的方志,呈现出不同的特点。这一现象和魏晋南北朝时期的时代特点有紧密的联系,结合时代特点来考察此一时期的方志,才会在总体上得出一个比较客观的评价。  相似文献

Cryptocrystalline silicates from the Chadron Formation were widely used by prehistoric human groups in the Great Plains of North America. There are two documented quarry areas: Flattop Butte in Colorado and the White River Badlands of South Dakota. Cryptocrystalline silicates from these sources are visually indistinguishable, making it difficult to determine the sources of artefacts found at archaeological sites. In this investigation, neutron activation analysis is used to distinguish the two sources. This technique also identifies lithic material from the Clovis-age Eckles site in Kansas as being from Flattop Butte.  相似文献

十六国北朝特别是十六国,频繁而大规模的内部人口流动,是由胡族统治者实施的,并以强制迁移性质为主,强制迁移的目的,是以之为兵、用之耕耘。这样的移民状况加上其他复杂因素,决定了长期、普遍、广泛设置于东晋南朝的侨州郡县,在十六国北朝境内,总体上说,是不长期、不普遍、不广泛的。十六国北朝特别是十六国的多数侨州郡县,既无土地也无人民。如十六国的侨置,多与"虚设"无异;至于北朝的侨置,则不外以下几种情形:因招抚或安置流民而置,为安置特殊性质的移民而设,备职方而立,务广虚名,以及承东晋南朝之侨置而不废者。十六国北朝侨州郡县与侨流人口的考证与研究,既要具备与东晋南朝进行比照的观点,其研究难度也较之东晋南朝为更大。  相似文献

清代塞外围场格局与动物资源盛衰   总被引:1,自引:0,他引:1  
清代的塞外围场,建于山深林茂之区,有丰富的动植物资源,地域相连,功能各异,政治军事地位十分重要。清皇室决定着围场资源的利用方式和占有形式,康乾时期不间断的军事演练式的行围对围场动物资源衰减有重要影响,嘉道停围后,骑射演武的军事功能荡然无存,但动物资源衰减依旧势不可遏。塞外围场分布格局、资源存在结构及分配形式改变,围场体系完结。  相似文献
