明清丝绸之路哈密—吐鲁番段“沙尔湖路”研究

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。     

Methods of soil P analysis in archaeology

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).     

Iktomi in the Land of the Maymaygwayshi: Understanding Lived Experience in the Practice of Archaeology Among American Indians/First Nations

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.     

A Rock‐Magnetic Quest for Possible Ore Sources for the Ancient Iron‐Smelting Industry in the Olkhon Region (Lake Baikal,Siberia)

Rock‐magnetic techniques were used to examine the topsoil layer of Kurma archaeological site (in the Olkhon region, on the north‐western coast of Lake Baikal, Siberia) in an effort to determine the possible sources of iron ores for iron‐smelting centres (at about the bc /ad boundary). Measurements have shown a magnetic enhancement of the topsoil due to magnetite grains resulting from weathering of strongly magnetic crystalline rocks. They have also revealed a preliminary picture of the distribution of strongly magnetic topsoils around the ancient iron‐smelting centres. Perhaps, in addition to traditional sources of raw materials, the ancient metallurgists used black sand talus as an ore deposit.     

Top-down or bottom-up: rural settlement and raised field agriculture in the Lake Titicaca Basin, Bolivia

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.     

王安石·《湖田疏》·“废湖为田”

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。     

Embodied bicycle commuters in a car world

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.     

The fish of Lake Titicaca: implications for archaeology and changing ecology through stable isotope analysis

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.     

游地社区恢复力认知测度与影响因子分析——以千岛湖为例

人是社会-生态系统的主要决定性因素,旅游地社区恢复力提高是旅游地可持续治理的关键。运用通径分析方法,从治理、社会、经济及生态系统4个维度建立社区恢复力认知测度模型,定量测度千岛湖社区认知恢复力,识别脆弱性及应对能力认知对社区恢复力的复杂影响。结果表明：①社区恢复力认知可提取8个因子,政府治理在社区恢复力中的作用最为显著,是社区恢复力提高的主导力量。②千岛湖恢复力认知综合平均值为2.42,处于中等偏下水平。社会子系统恢复力认知值最高,生态和经济子系统恢复力认知值最低,系统发展应关注生态资本的积累与保护以及经济发展的多样性与稳定性。③社区脆弱性、个体和政府应对能力的各变量对社区总恢复力及各维度认知呈现出错综复杂的关系,政府应对能力对总恢复力及各维度认知的影响相对最强,个体应对能力对多数恢复力认知维度未产生明显影响。需进一步发挥个体作用,促进个体和政府的共同参与,提高社区恢复力。     

清代太湖流域的环境与卫生——以外国人的游程与感觉为中心

太湖流域是一个独立的地文系统,自唐宋以来的经济开发和商业化发展,使这里的民生显得异样繁荣。地方史料中的绝大多数,谈论的都是这里的高额赋税负担和内部经济生活的多样化及地区差异,对于民众生活的环境与卫生问题,直接性的详细记载极少。清代中后期外国人在这一地域内的众多游记和日记,于这方面却有颇为细致的描述,侧重点大多在河流环境、建筑居住、城镇街道景观和饮食卫生等问题,负面性的评述占据了大多数。这一当中固然有太平天国战乱后的影响内容,也有中国人的许多常态生活习惯,更带有外国人的猎奇与鄙薄的眼光,但是在总体上都可反映出中国人长期并不真正重视的环境问题及相对淡漠的卫生观念。而所谓"近代化"的理论推导,大多仅限于1843年开埠后沿江滨海重要城市的一些证据,其实并不符合太湖流域广泛城乡的实际生活。
