《中俄蒙协约》签订后中国政府与自治外蒙古的关系

文章认为《中俄蒙协约》签订以后,中国政府与外蒙古自治官府有了直接来往,双方在巴布扎布匪帮问题和册封问题上有矛盾和斗争;中国政府在册封、处理德奥俘虏、处理恰克图边防问题上行使了一些主权;双方在收回唐努乌梁海一事上有所合作;中国内地与自治外蒙古的经济联系、人员往来有所增加。     

TSONGO,A SMALL LAKE IN NORTH TIBET

The Qinghai-Tibet Plateau has the most lakes of any area in China. The total surface area of the modern plateau lakes accounts for 52 percent of the total surface area of lakes in China. There are countless smaller lakes around the Serling Tso, which somehow unexpectedly became the biggest lake in Tibet after the sudden rise of the water level in 2004. One of them, Tsongo, has a shoreline shaped like a dancing fairy with curvy lines,     

“釜底之水”: 明清时期文安洼的水患与治理

河北文安、大城两县境内的文安洼,地处大清河、子牙河水系下游,地势低洼,“形如釜底”,导致积水难以泄出,历史时期常发生严重的洪涝灾害。明清时期文安县通过修筑堤防、开凿引河、营田种稻等多种措施治理文安洼,但水患仍频。文安洼水患难以治理的原因,既包括文安洼区域本身低洼的地形与大清河、子牙河下游流域淤高等环境因素,也包括文安县与周边州县之间治水利益的矛盾及文安县自身的治理乏术、乏力等社会因素。     

上元应节骨牌灯戏考辨

本文以戏曲史中鲜为人所关注的骨牌灯戏为研究对象,勾连清代宫廷内外相关材料,对民间与宫廷中的骨牌灯戏进行比较研究。通过对演出形式、唱词、队列变换、人员构成、灯具等方面的对比来分析二者的源、流等问题,尤其是它与节令戏曲等的渊源关系。提出骨牌灯戏是中华优秀传统文化的缩影。     

中国西南边境新冠肺炎疫情防控的尺度分析——以瑞丽为例

边境地区的新冠肺炎疫情防控受到不同行动主体在多尺度空间上的话语和实践的影响,其成效关系着全国疫情防控成败的大局。本文以云南边境城市瑞丽为对象,运用网络文本分析和网络式访谈法,基于尺度概念化框架对瑞丽市边境新冠疫情防控进行尺度本体、尺度隐喻及尺度实践分析。结果表明：在尺度本体上,国家、地方尺度实体推动疫情防控边界向内延伸,实现了物质边界的再生产;在尺度隐喻上,权力机关运用尺度话语展现疫情防控中的国家意志,极大凝聚了社会各界人士的精神边界,进而削弱了物质边界对人们造成的障碍;在尺度实践上,政府自上而下的疫情管控政策层层下移和普通大众自下而上的防控措施层层上推建构了人、物一体的边界,形成了双重性的再边界化景观,有效发展和巩固了中国内向性边界。     

The Historical Tradition and Mission of Chinese Archaeology

Chinese President Xi Jinping, gave an important speech describing the great achievements and significance of Chinese archaeology, pointing out the way forward for the development of Chinese archaeology in the new era. By reviewing the century-long history of Chinese archaeology, its historical tradition and the mission of the times are distinctive. Since 1949, under the guidance of archaeological culture theory and regional systems and cultural types theory, Chinese archaeology has made a series of significant achievements and taken up the mission of the times in inheriting historical traditions and exploring major issues including the origins of Chinese civilization. The current development of Chinese archaeology should further the historical tradition of Chinese archaeology under the guidance of the spirit of Xi Jinping’s speech. From a longitudinal perspective, Chinese archaeology should strengthen the research on the origin of Chinese civilization and its characteristics, development trajectory, major landmark achievements, and the way of civilization inheritance after its formation, especially to strengthen the exploration of how the“5,000-year continuous unity” was formed after the unification of the Qin and Han dynasties. From a horizontal perspective, with the Belt and Road Initiative as the main thread, we should continue to strengthen archaeological research on cultural exchanges between China and foreign countries, advocate mutual appreciation of civilizations, tell the Chinese story well, and contribute Chinese historical wisdom and experience to the world. On the whole, we should strengthen the theoretical construction and ability training of archaeology, strive to build Chinese archaeology with salient Chinese features, style, and ethos, and realize the historical mission of the new era of the Centennial“Chinese Dream.”     

Examining quartz OSL age underestimation for loess samples from Luochuan in the Chinese Loess Plateau

When using quartz OSL to date loess samples from the Chinese Loess Plateau, it has been reported that the agreement between OSL ages and the independent ages is limited to the samples younger than ～70 ka with a corresponding D_e of ～230 Gy, and a sample with an expected age of 780 ka was dated to 107 ka, corresponding to 403 Gy. The growth curves of these samples do not saturate at doses of 700 Gy, and a linear growth part was observed for doses higher than 200 Gy. However, the maximum measured age of ～100 ka imply that the D_e determined using this linear part of a growth curve could be problematic, or that the quartz OSL signal is not as stable as previously thought and has a barrier age of ～100 ka. In the current study, we examine the reasons for the age underestimation. We examined the shape of growth curves, anomalous fading, thermal stability, etc. The results show that, for the loess samples examined, quartz OSL does not fade anomalously, and the barrier age of ～100 ka is due to the fact that the OSL signals are less thermally stable, the lifetime of 0.311 Ma at 20°C obtained is much smaller than those for quartz samples from other regions such as Australia (～100 Ma).     

胡宗宪《吕港帖》与乍浦之捷考

《吕港帖》是明代胡宗宪致沈良才的一封信。胡宗宪在向上级汇报抗倭作战情况的同时,明确了倭寇驻扎的时间、地点以及胡宗宪拟布置兵力的时间,并说明了作战将领的心理状态。作者就信中人物和事件进行考证,推论出信中涉及的是明嘉靖三十五年七月江浙总督胡宗宪指挥的一次抗倭战事,即胡宗宪撰《筹海图编·大捷考》一章中的"乍浦之捷"。作为个案,《吕港帖》也反映了尺牍丰厚的文献价值。
