殷墟卜辞中有四方风名 ,是研究商代思想的重要资料。本文认为 ,四风应是象征四种气候 ,后世哲学思想中的“气” ,应是源自商代自然崇拜中的“风” ,古人认为“风”是“天地之使” ,故卜辞中有“帝史风” ;古人还认为“风”是天之命令 ,故四风象征天命。  相似文献

The almost ubiquitous presence of small amounts of iron in ancient coins gives them remanent magnetic properties which can be measured easily on commercial magnetometers. The stability of the remanence suggests that ancient coins might retain information about the geomagnetic field at the time and location of manufacture and so be valuable in setting up archaeomagnetic dating curves. However, measurements show that the remanence directions tend to be too scattered for this purpose, although it is quite possible to distinguish magnetically the obverse and reverse faces of struck coins.Saturation remanence studies of coins and coin analogues indicate that the main carrier of the remanence in struck coins is precipitated fine-grained iron (rather than the oxides of iron) which is produced during the minting process. The intensity of the remanence generated depends upon the thermo-mechanical history of the flan prior to striking, which suggests that the magnetic properties of such coins are not simply related to the provenance of the ores used.  相似文献

This historiographic essay contends that warfare made and unmade the Qing dynasty between 1644 and 1911, and its study has helped to create the field of modern Chinese history during the past seventy years. It advances three principal claims. First, the literature on war, especially interstate conflict, can serve as a synecdoche for the development of the modern China field as a whole since the 1950s. The research interests of late Qing specialists have oscillated along an “external-internal-external” axis that corresponds with three distinct periods of intellectual inquiry, scholarly production, and generational dominance. Second, historians have reached inaccurate conclusions about the state capacity of the Qing Empire after 1840 through a crude analysis of the First Sino-Japanese War, a mistake they can rectify by adopting a longer-term perspective on the state-making process. Third, scholars have deftly traced the changing role of military power in modern Chinese politics but have also adopted the interpretive categories of wen and wu from literati discourse without sufficient critical reflection. In the future, researchers may seek to explore the intersection of warfare and the environment, technology, and ethnic identity, approaches that will continue to move the field in comparative, global, and Inner Asian directions.  相似文献

东西对话:中国政治地理学研究展望   总被引:2,自引:0,他引:2  
中国政治地理学的发展尚处于起步阶段。中国与西方政治地理学者的学术交流相对有限,这主要是由于语言的障碍,以及中国学者对于研究课题政治敏感性的担忧,普遍缺乏对政治地理学研究内涵的理解。本文基于对中西方政治地理学发展现状及相关研究可能性的理解,指出以下五个在中国具有进一步拓展空间的政治地理学课题:广域行政与空间政治;国际关系与地理想象;边界冲突与划界研究;边界与边界区域研究;环境政治地理学。这些课题的开展不仅可以加强中国自身的政治地理学研究,而且对西方正在进行的政治地理学研究也会起到积极的推动作用。  相似文献

转型中国的地方管治:海外学者的观点   总被引:1,自引:0,他引:1  
改革开放以来,中国的城市与区域在分权化、全球化和市场化的宏观背景下,经历了剧烈的政治、经济和社会转型,地方管治成为城市地理学研究的热点问题。本文对海外研究中国地方管治的有关文献进行综述,总结了目前主流理论对中国地方管治变革的两种观点-强势的地方政府与低效的地方政府,并做出评述。研究同时也指出深化中国地方管治研究和地方政府间关系研究的新方向。  相似文献

新中国区际粮食流通的三次变化及其原因分析   总被引:3,自引:0,他引:3  
新中国50多年间,粮食流通经历了计划调拨到市场调节的变化过程。在这一变化过程中,粮食流向流量发生了由南粮北调到北粮南运到北出南进乃至南北同出三次历史性变化。通过对这一过程和相关因素的分析可以看出,这三次重大的历史变化既是中国区域经济在市场化主导下非均衡发展的结果,同时,它又将对区域经济和国民经济、世界经济的进一步发展和调整产生重大的影响。  相似文献

ABSTRACT

This viewpoints paper reflects upon the journey youth geographies have travelled over the last 20 years and highlights some thoughts on where directions for new research might be best placed in the coming decades. In particular, the paper draws attention to the growing numbers of youth in the Global South and especially in the African continent where youth populations are set to continue to rise. The paper identifies some of the potential challenges faced by the majority of youth in coming years in particular the need to decolonise thinking around youth geographies while also considering the importance of economic, social and political contexts in shaping debates. The paper charts some potential new directions while also suggesting that youth’s own perspectives need to receive greater prominence in theory and outcomes.  相似文献
