This study address the question of the use and function of Early Neolithic (4000–3000 cal. BC) funnel-beaker pots from Mälardalen in eastern Central Sweden. The material studied is pottery from a wetland offering at the site Skogsmossen in the province of Västmanland. While deposited under ritual circumstances in a fen, the pots were likely used in a domestic domain on the settlement adjacent to the offering fen, prior to final deposition. The lipid analysis indicate a varied vessel use, there are traces of aquatic resources, plants, terrestrial animals and milk. The identification of milk residue is the oldest so far from Sweden.  相似文献

试论清代皇帝明黄色朝袍的功用   总被引:2,自引:0,他引:2  
在清代皇帝冠服中,明黄色朝袍的功用尤其引人关注。但是,长期以来人们对“朝祭所御”的概念往往含混不清,以至认为清帝明黄色朝袍既可亲郊飨庙又能御殿朝贺,模糊了朝服与祭服的区别。顺治十年(1653年)都察院左副都御史傅景星奏言:“自古帝王一代之兴,必有一代之制,黄帝尧舜垂衣裳而天下治。衮冕黼黻代有不同,朝有朝服,祭有祭服,所以肃臣民而格上下也……”。本文旨在讨论清帝明黄色朝袍的不同作用,从而区分出朝服与祭服的不同。  相似文献

Research on past human diets in the southern Lake Titicaca Basin has directed us to investigate the carbon and nitrogen stable isotopes of an important dietary element, fish. By completing a range of analyses on modern and archaeological fish remains, we contribute to two related issues regarding the application of stable isotope analysis of archaeological fish remains and in turn their place within human diet. The first issue is the potential carbon and nitrogen isotope values of prehistoric fish (and how these would impact human dietary isotopic data), and the second is the observed changes in the fish isotopes through time. Out of this work we provide quantitative isotope relationships between fish tissues with and without lipid extraction, and a qualitative analysis of the isotopic relationships between fish tissues, allowing archaeologists to understand these relationships and how these values can be applied in future research. We test a mathematical lipid normalization equation to examine whether future researchers will need to perform lipid extraction procedures for Lake Titicaca fish. We also analyze a number of aquatic plants to better understand the range of isotopic signatures of the Lake Titicaca ecosystem. We use these data to better understand prehistoric human diet and the role that fish may have played in the past as well as potential changes in local lake ecology through time.  相似文献

Intensive agricultural systems interact strongly and reciprocally with features of the lands they occupy, and with features of the societies that they support. We modeled the distribution of two forms of pre-European contact intensive agriculture – irrigated pondfields and rain-fed dryland systems – across the Hawaiian archipelago using a GIS approach based on climate, hydrology, topography, substrate age, and soil fertility. Model results closely match the archaeological evidence in defined locations. On a broader scale, we calculate that the youngest island, Hawai'i, could have supported 572 km2 of intensive agriculture, 97% as rain-fed dryland field systems, while Kaua'i, the oldest island, could have supported 58 km2, all as irrigated wetland systems. Irrigated systems have higher, more reliable yields and lower labor requirements than rain-fed dryland systems, so the total potential yield from Kaua'i (49k metric tons) was almost half that of Hawai'i (97k metric tons), although Kaua'i systems required only 0.05 of the agricultural labor (8400 workers, versus 165,000 on Hawai'i) to produce the crops. We conclude that environmental constraints to intensive agriculture across the archipelago created asymmetric production efficiencies, and therefore varying potentials for agricultural surplus. The implications both for the emergence of complex sociopolitical formations and for anthropogenic transformation of Hawaiian ecosystems are substantial.  相似文献

Archaeological charcoal remains are often used to reconstruct local woodland composition in the past, but rarely address how and why people may have selected specific woody taxa for particular purposes. Models from the field of human behavioral ecology predict that people forage for wood resources by taking into account the relative usefulness, abundance, and handling time related to procuring different wood types. Archaeological and ecological data from the site of Gordion, in Central Anatolia (modern Turkey), were used to test expectations associated with such models. Results suggest that inhabitants of Gordion used wood types for fuel in proportion to their local availability, but that they selected specific, more distant woods for construction. In most occupation periods pine was preferred for construction, perhaps because it produces long, straight timbers for roofing, despite the distance at which it grows from the site. This case study demonstrates that behavioral ecology modeling can help to distinguish between multiple wood acquisition strategies potentially used in the past and improve our understanding of wood use from archaeological charcoal remains.  相似文献

During the three-month long Sino-Japanese hostilities in the summer of 1937, Shanghai industries suffered the heaviest loss ever sustained during any previous military conflict in the city. Yet as has been shown in a previous study, local industries seem to have recovered fairly quickly. All statistics point to a return to pre-war levels of production in most sectors by the end of 1938 in some cases and during 1939 for most industrial branches. The purpose of this paper is to try to highlight the spatial dynamics at work in this recovery process. It relies not just on original sources, but on the unique capabilities GIS offers in processing large amounts of historical data and exploring connected issues in land use, demography, and urban life. The paper argues that Shanghai industries went through a thorough phase of relocation and migration within the city, but also of inbound migration from the surrounding regions. This study is based on a particular set of documents produced by the Shanghai Municipal Council, the largely independent body that administered the International Settlement. In this study, therefore, I shall argue that what happened in the territory of the International Settlement mirrored what happened next door and possibly in other parts of the Chinese-administered/Japanese-occupied areas. Beyond the issue of industrial movement, this paper also examines connected issues in land use, demography, and urban life.  相似文献

Current research on the cartography of the Venetian Empire rests on a state-centred perspective which reduces maps to mere technical tools in the service of maritime expansion and colonial government. In contrast, this paper argues that such an approach cannot sufficiently account for the multiple ethnocartographic transactions between Venetian authorities and local communities which defined Venetian map-making projects. Taking the seventeenth-century conquest of the Peloponnese as its focus, the paper proposes to rethink the Venetian cartographic archive as constituted through a set of socio-cultural and political practices involving both colonial surveyors and native inhabitants. By analysing the assemblage of cartographic knowledge in the context of the encounter between colonisers and colonised, the paper examines topographical surveys as the product of cross-cultural communication shaped through negotiation, competition and unequal dialogue. Ultimately, the paper aims to show the heuristic value of a dialogic approach to cartography for a better understanding of both the colonial society of the Venetian Peloponnese and the making of knowledge in Venice's overseas empire.  相似文献

有明一代,河南省曾进行了三次土地丈量活动:第一次在明初洪武年间,丈量出的土地数字仅是当时开垦的土地数,不能反映全省实有的土地数量。第二次在明中期嘉靖年间,是在一种错误思想的指导之下进行的,丈量之后又以“符合原额”为宗旨,大量进行了折亩活动,故丈量出的土地数字既不能反映当时河南省的开垦耕种数,也不能反映当时实有的土地数字。第三次是在明中后期万历年间进行的,指导思想明确,法令严格,方法得当,丈量出的土地数字既能反映当时河南省的开垦耕种数,又代表了全省实有的耕地数字。  相似文献
