明清丝绸之路哈密—吐鲁番段存在一条自哈密西南沙尔湖转西北至鄯善进而抵达吐鲁番的“沙尔湖路”,它与“黑风川道”“小南路”等传统路线均不同。利用《蒙古山水地图》等文献,可对沙尔湖路具体行经进行考证复原。该路沿线地形平坦,有泉水与植被,在明廷与吐鲁番、清廷与准噶尔在哈密的政治和军事对峙阶段曾广泛使用,后因泉湖干涸、气候炎热而中断。  相似文献

Methods of soil P analysis in archaeology   总被引:2,自引:0,他引:2  
Phosphorus (P) is unique among the elements in being a sensitive and persistent indicator of human activity. It has long been of interest to archaeologists because of its potential to inform them about the presence of past human occupation and to offer clues regarding the type and intensity of human activity. A wide variety of methods have been developed in both soil science and in archaeology to extract and measure soil P, resulting in a tremendous amount of data and a wide array of interpretations, but also considerable confusion over appropriateness of methods and terminology. The primary purpose of this paper is to address these issues by clarifying soil P analyses. Anthropogenic additions of phosphorus to the soil come from human refuse and waste, burials, the products of animal husbandry in barns, pens, and on livestock paths, or intentional enrichment from soil fertilizer. Once added to the soil, phosphorus in its common form as phosphate is stable and generally immobile in soils. Soil P comes in many forms, organized for the purposes of this paper on the basis of extraction and measurement procedures as (1) extraction for available P (Pav); (2) portable field techniques (the spot test or ring test); (3) chemical digestion of a soil sample for total P (Ptot); (4) extractions of inorganic P (Pin) for fractionation studies and extractions to look at individual compounds of P; (5) measurements of organic P (Porg); and (6) extractions for total elemental analysis. To compare the suitability of various extractants as the “best” indicator of human input and activity we subjected samples from three very different archaeological sites (Lubbock Lake, TX; Hulburt Creek, IA; British Camp, WA) to four methods of soil P extraction: perchloric acid digestion (Ptot), sulfuric–nitric acid extraction Ptot), hydrochloric acid extraction after ignition (Pin), and citric acid extraction (Pav). Further, methods of measurement were compared via colorimetry vs. Inductively Coupled Plasma (ICP) spectrometry, and the two methods of supposed “total P” were both measured via ICP. In general, the stronger extractants yielded more soil P, but the result are not clear-cut. Likely variables include the intensity of occupation, nature of the parent material, and postdepositional weathering (e.g., the addition of dust).  相似文献

In discussions concerning American Indians/First Nations and the practice of archaeology in North America, the issues are typically presented in a polarized fashion with American Indians/First Nations on one side and archaeologists on the other. Frequently the literature discusses how archaeologists should modify their practice in response to the needs of American Indian communities. Very little of the literature looks at the roles and challenges faced by American Indians who choose to pursue archaeology. This paper addresses this latter issue by examining my own work among First Nations communities in Ontario, Canada. Through the lens of ‘lived experience’, I will examine the interplay of identity, personal and communal histories, and the contemporary situation of my self and the First Nations communities I worked with, looking at how having ‘insider’ knowledge can be both useful and a handicap in fieldwork.  相似文献

试论马桥文化与中原夏商文化的关系   总被引:4,自引:0,他引:4  
曹峻 《中原文物》2006,(2):40-45
夏商时期位于东南太湖地区的马桥文化,同中原夏商文化在文化内涵上存在着许多相关性,但在更深层次的思想、制度乃至政治关系上,马桥文化则还未纳入中原夏商王朝的势力范围内。尽管如此,夏商时期的马桥文化正处于太湖地区从良渚时期较为封闭的对外关系、到吴越文化时期全方位同外界进行交流的中间结点上,因此在太湖地区早期古文化对外关系的发展过程中,马桥文化处于一个承上启下的位置。  相似文献

Differing interpretations regarding the organization of past intensive farming are often distinguished as “top-down” or “bottom-up” perspectives. The development of intensive farming and its social organization are attributed to either nascent states and centralized governments or the incremental work of local communities or kin-based groups. We address the social organization of raised field farming in one region of the Lake Titicaca Basin of the Andean altiplano, Bolivia. We evaluate past research in the Katari Valley, including our own, based on recent settlement survey, excavation, and a variety of analyses. Taking a long-term perspective covering 2500 years, we find that relations of production and rural organization changed greatly over time in relation to changing sociopolitical conditions. Local communities played dynamic roles in the development and organization of raised field farming, yet its intensification and ultimate recession were keyed to the consolidation and decline of the Tiwanaku state. We conclude that the top-down/bottom-up dichotomy is overdrawn. Local communities and their productive practices never operated in a political or economic vacuum but both shaped and were transfigured by regional processes of state formation, consolidation, and fragmentation.  相似文献

在南京玄武湖的历史上,700年来一直记载王安石作《湖田疏》奏请将玄武湖"废湖为田",其实《湖田疏》是一篇伪作,王安石的"废湖为田"案是一桩历史冤案。  相似文献

As an initiative to increase cycling, bike to work (BTW) events emphasize a pragmatic approach in which people learn through sensory experience. Pragmatism contends that the lived experience of the commuter within fluid geographies of social and physical conditions informs commuting knowledge and behavior. I researched how bicyclists participate in the 2012 BTW event in Lake Tahoe (USA) and how these experiences facilitate the process of becoming bicycle commuters. My study included participant observations, interviews, video observations, and route mapping. I analyzed this data with thematic and narrative analyses. I find that the BTW event illuminates bicycling, a normally invisible practice in a car world, and creates temporary bicycle-friendly spaces that provide the embodied experience and knowledge of bicycle commuting within context. Through this lived experience, participants can break free from unconscious car-based patterns and become embodied bicycle commuters who engage in active renegotiations of their commuting practices.  相似文献

新石器时代,南北陶器装饰已出现不同面貌,大体说来,黄河中上游为一种,表现为彩绘的样式:长江中游为一种,表现出素面刻划的特征。造成差异的原因,地理资源即无机质矿物颜料的多寡是第一位的,这一推论大体符合彩陶分布状况,和历史献记载以及现代探矿资料。  相似文献

历史时期射阳湖演变模式研究   总被引:2,自引:0,他引:2  
射阳湖历史上曾是江苏境内著名的大湖。历史时期,湖区经历了浅水海湾—古泻湖—淡水湖泊—沼泽性湖泊—平原沼泽的演变模式。春秋以前,本区是里下河浅水海湾的一部分;春秋至唐代,本区由古泻湖逐步演变为淡水湖;南宋以来,1128年黄河夺淮以后,大量泥沙进入本区,湖区淤积迅速,成为沼泽性湖泊,加之人类开发活动的深刻影响,射阳湖逐渐演变为里下河平原的一部分。  相似文献

史前太湖流域,礼器出现在社会初步分化的崧泽文化时期;良渚文化时期已经是一个分层的复杂社会,社会成员分化成为不同的等级、阶层,与此相适应,太湖流域史前社会出现了陶质、石质和玉质三种不同质地的礼器,并有着比较严格的使用制度,太湖流域史前社会的礼仪制度初步形成。  相似文献
