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

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

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

Archaeobotanical survey has sampled a series of late Neolithic to early Bronze Age settlements in the upper Ying valley (part of the central plain of China) and provided useful data for understanding prehistoric arable ecology and farming during a period of increasing local social complexity. A combination of the modelling functions offered by Geographic Information Systems (GIS) and the data reduction possibilities offered by Principal Component Analysis (PCA) allow us to explore possible relationships between local arable ecology, crop-processing strategies and the natural environment. The results should be treated cautiously given the size of the analytical sample but suggest that differences in the natural environment around each site may explain varying patterns of wild food collection, while social and cultural factors may better explain variation in farming practice and crop-processing at different sites.  相似文献
