Located in the Central Plains of China, the early Xia Dynasty site of Xinzhai (2050 BC–1750 BC) with large archaeological features and exquisite artifacts of jade and copper is pivotal for probing the origin and formation of Chinese civilisation. Here, stable isotope ratios analysis, supplemented by zooarchaeological results, was used to investigate the exploitation and management of animals utilised by humans. It was demonstrated that a diverse pattern of animal raising and exploitation was present at the Xinzhai site. The domestic pigs were fed with substantial amounts of millets or their byproducts to guarantee a food source for the dietary demands of the humans. Dogs were also found to have consumed large amounts of C₄ protein sources, likely in the form of human food scraps or leftovers. The domestic herbivores, sheep and cattle, showed different dietary characteristics in that the former mainly grazed in the natural environment, while the latter species were fed with large amounts of C₄ products. This intra‐species variation was somewhat related to their physiological characteristics but seems to have been more determined by their different status in social and ritual activities. Thus, this research at Xinzhai provides a glimpse of the organisation of animal resources during the initial formation of Chinese civilisation.

Fluid chemistry and microbial community patterns in chimney habitats were investigated in two hydrothermal fields located at the Central Indian Ridge. Endmember hydrothermal fluid of the Solitaire field, located ~3 km away from the spreading center, was characterized by moderately high temperature (307°C), Cl depletion (489 mm ), mildly acidic pH (≥4.40), and low metal concentrations (Fe ≤ 105 μm and Mn = 78 μm ). Chloride depletion indicates that the subseafloor source fluid had undergone phase separation at temperatures higher than ~390°C while the metal depletion was likely attributable to fluid alteration occurring at a venting temperature of around 307°C. These different temperature conditions suggested from fluid chemistry might be associated with an off‐spreading center location of the field that allows subseafloor fluid cooling prior to seafloor discharge. The microbial community in the chimney habitat seemed comparable to previously known patterns in typical basalt‐hosted hydrothermal systems. Endmember hydrothermal fluid of the Dodo field, standing on center of the spreading axis, was characterized by high H₂ concentration of 2.7 mm . The H₂ enrichment was likely attributable to fresh basalt–fluid interaction, as suggested by the nondeformed sheet lava flow expansion around the vents. Thermodynamic calculation of the reducing pyrite–pyrrhotite–magnetite (PPM) redox buffer indeed reproduced the H₂ enrichment. The quantitative cultivation test revealed that the microbial community associated with the hydrothermal fluid hosted abundant populations of (hyper)thermophilic hydrogenotrophic chemolithoautotrophs such as methanogens. The function of subseafloor hydrogenotrophic methanogenic populations dwelling around the H₂‐enriched hydrothermal fluid flows was also inferred from the ¹³C‐ and D‐depleted signature of CH₄ in the collected fluids. It was observed that the hydrothermal activity of the Dodo field had ceased until 2013.  相似文献

Pre‐earthquake and postearthquake temperature changes were documented in two hot springs at Xiangcheng. Pre‐earthquake changes were documented in spring I, 13 days before and 106 km away from the M_s 5.8 Zhongdian earthquake. The 11‐year cutoff spring spouted again, and the spouted water was 24°C hotter than the former escaping gas. Postearthquake changes were documented in spring II following the 2008 M_w 7.9 Wenchuan earthquake, approximately 425 km away from the epicenter. Temperature in spring II showed a step‐like increase with a magnitude of 4°C induced by the earthquake. Spring I which is 0.3 m apart from spring II did not show a sudden change following the earthquake. However, temperatures in the two springs were identical after the Wenchuan earthquake. It indicates that the earthquake generated new hydraulic connectivity between springs I and II, and the heat transport between the two springs accounts for the postearthquake temperature changes.  相似文献

Contact with nature is vital for the development of children and teenagers. In the past, informal urban green spaces (IGS) such as vacant lots appear to have been used for such purposes. We need to better understand how previous generations used IGS to make sure young people today can also enjoy its social, mental, emotional and physical health benefits. This study quantitatively compared adult residents' memories of IGS use in their childhood and teenage years in two geographically and culturally distinct cities: Brisbane, Australia, and Sapporo, Japan. The results showed most respondents (>70%) remembered using IGS in the past, and preferred it over other green space because it was easily accessible. Most (>70%) recalled experiencing no problems (e.g. danger of injury) when using IGS, a contrast to recently increasing parental concern for children's safety. Such factors may limit present IGS use and prevent it from fulfilling the important role it played for previous generations' recreation.  相似文献

The provenance of the highly radiogenic lead (HRL) contained in Chinese Shang bronzes has attracted great scholarly attention in recent years. A new study of the Hanzhong Shang bronzes has put forward a hypothesis that the HRL metal may come from the adjacent Qinling Mountains. This article reanalyses the lead isotope ratios and alloy compositions of the Hanzhong bronzes. Combining the analytical results, the modern ore data and the slags from Guanzhong area, we propose that there is no direct evidence to identify Qinling as the provenance of HRL metal (especially lead). Whilst over 80% of the Hanzhong bronzes contain HRL, the indigenous artefacts containing both HRL and special alloying elements (As, Sb, Ni) account only for minor portions. This fact cannot verify that HRL originates from Qinling, and even makes it difficult to prove that most of the Hanzhong bronzes use local metal resources. An alternative argument might be that the HRL used in Hanzhong derived from the Shang dynasty. The use of HRL reflects a unified system for allocating metal resources centred on the Shang kingdom, which has great significance for further understanding of the resource circulation patterns among different bronze cultures and locations during the Shang period.  相似文献

The bronze wares of the Han Dynasty excavated in Chongqing are decorated with plating patterns, maintaining an exquisite lustre right up to modern times after the covering patina is cleared away. In this paper, a plated fragment of the Han Dynasty from the Wushan County Museum was characterized by combining optical microscopy (OM), scanning electron microscopy with X‐ray energy‐dispersive spectrometry (SEM–EDS), X‐ray fluorescence analysis (XRF), X‐ray diffraction (XRD) and X‐ray photoelectron spectroscopy (XPS). The results showed that the bronze fragment was gilded with a ~ 3 μm thick gilded layer and a ~ 20 μm thick silvered layer. The high concentration of Hg and Hg‐rich intermetallic compounds confirmed the existence of mercury gilding/silvering technology, for example, Au₉Hg in the gilded layer and Ag₁₃Hg₇ in the silvered layer. An ordered stripe structure was observed in the gilded surface, corresponding to the formation of rod‐like, intermetallic Au–Hg compounds. Specifically, a high concentration of Au was detected in the silvered layer. The exploration of gilded/silvered bronze casts light on this ancient technology and the benefit of identifying, protecting and reproducing it.  相似文献

This paper seeks to unpack the politics of heritage preservation in post-1997 Hong Kong. Referring to international frameworks on heritage preservation, it seeks to position Hong Kong’s cultural resource management on par with international discourses for the advancement of heritage governance. Debates surrounding heritage are indeed a part of the wider picture of Hong Kong’s cultural and identity politics and the Hong Kong-China relationship. By examining various contested cases of heritage conservation, and by linking those debates back to the government’s responses within the context of cultural governance, we suggest that heritage management has become a hot stove for cultural politics in post-colonial Hong Kong with deep repercussions in the political, social and economic spheres. The paper examines the rising social debates concerning the removal and conservation of built heritage, and the various government attempts to address these debates. It argues that the current heritage governance mechanism has failed to meet social needs and provide an articulated heritage policy. We propose that a coherent organisational structure is required to better accommodate diverse and contradictory views and discourses surrounding heritage and cultural governance and to tackle the various cultural challenges in postcolonial Hong Kong.  相似文献

The development of lacquerwares reached its peak between the Warring States Period and the Han Dynasty (390–87 bc ) in the Changsha region of China. By studying excavated fragments of lacquers from this period, this paper examines the constitution of various pigmented layers, such as red, black and white layers, coloured lacquer layers, namely reddish brown or reddish orange, dark‐coloured or black, and silver lacquer layers, using non‐destructive methods. In addition, the characteristics of lacquer production techniques in Changsha are also discussed in comparison with those of other regions in China during the same period of time.  相似文献

Chang'an (now Xi'an) was the capital of the Western Han Dynasty and the starting point of the Silk Road. In the light of the importance of Chang'an as the centre of politics, economy and cultural interaction, the overarching question proposed in this paper is focused on its role in the mirror production and distribution network during Han period. On the basis of chemical and lead isotopic analyses of 34 Han mirrors, this paper discusses the potential existence of a mirror production centre in Chang'an. Meanwhile, a comparative study with mirrors uncovered from the south‐western frontier and from Central Asian and North‐East Asian countries offers new insight into these related issues.  相似文献

The Yuzhen Palace is one of the nine palaces in the Ancient Building Complex built by order of the Yongle Emperor during the Ming dynasty. The buildings were built with dressed black bricks. As a result of the planned national South–North Water Diversion project, the water level in the Danjiangkou Reservoir that surrounds the Yuzhen Palace was expected to rise by approximately 15 m. To avoid submersion of the site, three gates were elevated by 15 m in 2013 and other buildings dismantled, for later reconstruction. The characterization of the construction materials has therefore become of primary importance. Here, we present results on the plasters of the Longhu Hall. The analysis of materials involved a multi‐analytical approach combining optical and electron microscopy with X‐ray and vibrational spectromicroscopies and thermogravimetry. The results indicated the use of two earthen plaster layers and a whitewash finish coating applied over a thin preparatory intermediate layer to improve the adherence of the finish coating to the earthen plaster. Ramie and straw fibres identified in the earthen plasters were added to reduce shrinkage and cracking during drying. The raw materials used and the application technique pointed to a well‐established construction industry using traditional earthen building materials together with lime technology.  相似文献
