汉景帝阳陵帝陵陵园内封土东侧外藏坑K16、K14及盗洞67中出土的动物骨骼共计18个属种29个个体,其中海洋性动物螺和蛤共计4个种12个个体,是这批动物骨骼的一大显著特征。海相动物的出现对外藏坑功能的研究提供了新的视角。文章结合动物骨骼标本及古文献资料对汉景帝阳陵周边环境做了初步的探讨。 相似文献

Stable isotope analysis of ancient skeletons has become a routine method and widely used to answer diverse archaeological questions related to the human (animal) diets since the initial study in 1977. However, this study in china is underestimated and much less unknown to international circles considering the infrequent publications in English journals. In this review paper, the research history in China was overviewed shortly and then, the research progresses concerning different research themes, such as the chronological trajectory of human diets, the development and spread of agriculture, the mechanism of animal domestication, human social hierarchy, and so on, were introduced in detail, trying to draw a rough framework of human dietary evolution given the unique Chinese geography and cultures. At last, the potential research directions were also suggested for the future studies. 相似文献

1988年中国社会科学院考古研究所内蒙古工作队发掘了敖汉旗孟克河右岸的榆树山和西梁(千斤营子)两个遗址.所出遗物与兴隆洼文化同类器相比,筒形陶罐与之相差较大,石器、骨器中有许多相同的器物,如石锄、石刃骨鱼镖等.西梁遗址所出的钻孔石器和环状器很有特色.艺术品中陶塑人头像和骨笛令人瞩目.根据其碳-14数据测定,两处遗址年代均为距今5000年以前. 相似文献

国家图书馆藏甲骨共有35600多片,是目前我国乃至世界上收藏甲骨最多的单位.其中8770片甲骨的拓片为<甲骨文合集>(以下简称<合集>)所收录[1],但由于<合集>所收的拓片大多没有核对过原骨,其中背拓有字而缺漏者,拓片模糊,脱落字或字的笔画的情况多有存在,从而导致释文中缺漏字、误释字的现象时有发生. 相似文献

本文围绕着对洋务企业中一个活跃群体即江南绅商崛起过程的细致分析,对学界此前观察中国近代绅商阶层的起源和中国近代工业化兴起进程的视角和进行历史定位的方式进行了反思.本文的研究表明,这两个历史事件决非是仅仅构成宏大叙事的重大事件,而是都包含着由冲击与回应、传统与近代、内因与外因、整体性与地方性等一系列二元关系发生复杂的交织和互动而形成的实践逻辑,也只有综合运用宏观与微观、自上而下与自下而上的视角,才能准确理解和把握这样的实践逻辑. 相似文献

In recent years, online volunteers have played important roles in disaster response. After a major disaster, hundreds of volunteers are often remotely convened by humanitarian organizations to map the affected area based on remote sensing images. Typically, the affected area is divided using a grid‐based tessellation, and each volunteer can select one grid cell to start mapping. While this approach coordinates the efforts of volunteers, it does not differentiate the priorities of different cells. As a result, volunteers may map grid cells in a random order. Due to the spatial heterogeneity, different cells may contain geographic information that is of different value to emergency responders. Ideally, cells that potentially contain more valuable information should be assigned higher priority for mapping. This article presents an analytical framework for prioritizing the mapping of cells based on the values of information contained in these cells. Our objective is to provide guidance for online volunteers so that potentially more important cells are mapped first. We present a method that is based on information value theory and focus on road networks. We apply this method to a number of simulated scenarios and to a real disaster mapping case from the 2015 Nepal earthquake. 相似文献

Numerous studies have studied how knowledge spillovers and various other factors influence industrial clusters in terms of geographical proximity. Related studies have generally confirmed significant positive correlations between firm innovative activities and factors such as spatial proximity and degree of industrial clustering. This study elucidates on an individual level, based on the relationship between proximity dimension and innovative activity, the interactive relationships between the mobility and interaction of high-tech talent and innovation performance. Survey results indicate that the spatial proximity of firms clustering within the Hsinchu and Tainan Science-based Industrial Park increases the interaction among high-tech personnel and the expansion of their professional networks, thus promoting innovation. Gradually organizational and social proximity evolve from physical proximity within high-tech districts via the evolution of industrial networks and interactions among high-tech talent. Additionally survey results demonstrate the value of mobility and informal relationships involving high-tech talent, as well as the effect of these relationships on innovation performance during the various stages of science park development. However, how to avoid lock-in in the future development of high-tech districts remains a critical issue. The results of this investigation provide a useful reference for planning and managing industrial districts. 相似文献
