透过法国制图家桑松1656年绘制的中国地图,揭示已佚的由耶稣会士罗明坚与意大利制图家内罗尼合作的1590年单幅中国大地图面貌,指出此图主体部分是由罗明坚依据《大明一统文武诸司衙门官制》所载中文舆图摹绘的抄摹型分省图稿拼合而成的,拼合主要基于对分省图稿省际河道比较随意的连接,造成水系、诸省轮廓及方位等重大错误。部分图示还借鉴1584年刻印的巴尔布达"中国新图"。此图是已知最早的单幅西文中国详图,虽有缺陷,但对中国地理面貌的展现较此前西文地图有所推进。  相似文献

本文的研究中,在内蒙古地区地质学、古地理学和环境演变方面已有研究成果以及考古与历史文献资料的基础上,修复和描述了内蒙古陆地形成以来的地质历史时期和人类历史时期内蒙古土地利用/覆盖时空演变过程,并探索其驱动机制与因素,从而为正确把握内蒙古地区近现代土地利用/覆盖变化时空轨迹提供科学依据。古代相当长的历史时期,内蒙古地区基本上被游牧民族所占据,达到了一种古代的可持续发展。清代中期以后,特别是进入20世纪以来,随着几次大规模的移民拓荒高潮,耕地面积急速扩展而草场面积日益退缩,内蒙古草原生态环境遭遇空前的破坏,沙漠化和草原退化急速加快,土地利用变化和土地利用方式成为了土地覆盖变化的最主要驱动因子。土地利用变化(开垦草原、毁林开荒)的驱动因子主要有人口因素、经济利益和政府决策等三个方面,而且每一次大规模开荒时期三者往往相辅相成,促成新一轮的开荒高潮。  相似文献

Settled by families from the South and the Northeast, during the 1800s Indiana was a cultural crossroads. Ceramic and faunal data recovered from excavations conducted at the Moore-Youse house and Huddleston farmstead in east central Indiana provide a relevant archaeological example of midwestern foodways during the nineteenth century. Vertebrate faunal material from the two sites reveals early use of wild resources followed by greater reliance on beef and pork after the 1850s. Stratigraphic analysis results of zooarchaeological information are also presented to illustrate diachronic trends in faunal use at the two residences.  相似文献

马克思以前的自然概念以非实践的方式来看待自然,割裂了自然与人、自然与历史、自然科学与人的科学的联系。马克思“感性的自然”突出了自然界与人的相关性;“人化的自然”强调了自然概念的社会历史性;“历史的自然”体现了自然与历史的辩证法;“人本学的自然”是对自然科学与人的科学分离的克服;“价值的自然”是对人与自然和谐的守望。  相似文献

This article analyzes the indoor climate that creates risk of damages in naturally ventilated churches in the cold climate of Estonia. Indoor temperature and humidity were measured over a one-year period and the results were analyzed on the basis of damage functions: mold growth, risk of cracking and fracturing of wooden objects, and delamination of the gesso layer of panel paintings.

In unheated churches, one of the most dominant problems was very high relative humidity throughout the year, creating a high risk for mold and algae growth. Churches may need background heating to avoid freezing during a long cold winter that causes low surface temperatures of massive walls during the spring–summer period. It was found that mold risk was significantly lower in heated churches than in unheated or intermittently heated churches. The risk of mold growth was not decreased by the use of intermittent heating.

In heated churches, overheating (room temperature >+10ºC) causes a RH below 50% during cold periods, and the favorable period for irreversible response of panel paintings was significantly longer, so there is a higher risk that the gesso may crack or delaminate. From the point of view of the cracking and fracturing of wood, indoor climate conditions are in the safe range for most of the year.  相似文献

This article aims at exploring Japan and its cultural and symbolic representation in the Republic of Letters from the end of the seventeenth century until the mid-eighteenth century. In order to do this, the article focuses on early modern scholarly journals, as they were the most comprehensive and up-to-date instruments of communication for the international community of scholars during that time. By analysing the journals’ content we will see which topics were more commonly connected to Japan and understand the role Japan played in the development of the increasingly comprehensive and methodical knowledge of the early modern savants. This article provides a picture of the heuristic and rhetorical role of Japan in the shaping of new, expanded representations of the world. On the one hand, connections between the cultural representations of Japan and other extra-European lands are highlighted; on the other hand, Japan's peculiar and unique features within the cultural and scientific discourses of the Republic of Letters are examined. Finally, how the representations of Japan relate to the divisions and identities within the Republic of Letters itself is considered.  相似文献

ABSTRACT

The French-born, nineteenth-century commercial cartographer, Constant Desjardins (1787?1876) remains a rather obscure figure, despite a productive career of more than four decades and his creation of a precociously designed atlas of Europe. Desjardins was a typical mapmaker of his age in his interest in thematic mapping, his use of the new technology of lithography, and his publication of materials primarily for the growing educational systems of Europe. Yet he was unusual in the increasingly nationalistic era of nineteenth-century Europe in that he produced multilingual as well as monolingual maps. He also crossed many state borders, working in France, Bavaria, Austria, Hungary and Serbia. Indeed, this cosmopolitanism may explain his relative obscurity.  相似文献
