气候变迁与商人南下

自然科学研究成果显示,距今4000年-3500年期间全球气温有过明显下降,这一降温事件对当时人类的活动产生了重大影响。建国前的商人正处于此次气候发生变异的时期,其活动地域的南迁与气候变化紧密相关。     

Developing a framework of Holocene climatic change and landscape archaeology for the lower Gulf region, southeastern Arabia

Geomorphological and geoarchaeological studies from the lower Gulf region of southeastern Arabia are increasing our knowledge of hydrological, ecological, and aeolian changes during the Holocene. Preliminary analyses of sediment records from two palaeolakes in the United Arab Emirates are presented, highlighting the potential of these sediment sources for providing high-resolution decadal studies of climate change and landscape evolution over the past 10,000 years. In order to study the society-environment relationship in this marginal region, a framework of environmental change is being developed against which the archaeology of the region can be set.     

“杨各庄”等地名的地理分布及其音变的历史意义

华北地区及华东地区地名中多见“X各庄”和“X家庄”。该地区中,从西北部到东南部,“X各庄”的比例逐渐增多,而“X家庄”的比例逐渐减少,形成了一个语音渐变的地理连续体。这种特殊现象的形成是由于该地区西北部较频繁地受到北方阿尔泰语系诸语言的影响,而相对来说,东南部则较少受到这种影响。地名中的“各”仍然保留了中古汉语“家”的舌根音塞音声母[k-]。这种明显的地域互补分布表明了北方汉语方言前高元音前面的舌根声母转变为舌面音的力量来自于外部的人文影响,而非内部语言音变。     

Mid‐Holocene Development of Mangrove Communities Featuring Rhizophoraceae and Geomorphic Change in the Richmond River Estuary,New South Wales,Australia

This paper describes the hitherto unreported occurrence of mid‐Holocene mangrove deposits in the Richmond River estuary, southeastern Australia, thereby providing evidence for changes in the distribution and composition of mangrove communities within a subtropical estuarine system during the Holocene. Stratigraphic, radiocarbon and palynological evidence indicates that widespread development of mangrove communities took place in the upstream reaches of the Richmond River estuary during the period 7000 to 6000 years BP. These communities maintained their habitat through substrate aggradation under the conditions of a moderate sea‐level rise, in contrast to other estuaries within the region, which generally experienced the submergence of intertidal substrates. Mangrove species belonging to the family Rhizophoraceae, most likely Bruguiera gymnorrhiza and Rhizophora stylosa, dominated these communities, in strong contrast to contemporary communities, which are dominated by Avicennia marina. Moreover, these mid‐Holocene communities were located a considerable distance upstream of the contemporary occurrences of Rhizophoraceae species within the estuary. The changes in the spatial distribution and composition of mangrove communities parallel the large‐scale evolution of the estuary driven by sea‐level variation. Shallow, buried Pleistocene terraces probably contributed to the regionally unique aggradational response of the mangrove communities and their substrates to a sea‐level rise during mid‐Holocene times.     

内蒙古赤峰市大山前第一地点夏家店下层文化的植被和生态气候

内蒙古赤峰市大山前遗址属于中国北方青铜时代早期文化遗存 ,出土了大量夏家店下层文化遗物 ,其年代为 2 0 0 0BC～ 15 0 0BC。本文对大山前第一地点 1996年发掘区中部的探方T4 0 6内F8H1灰坑出土的木炭碎块进行了种属鉴定 ,并对出土的不同树种的木炭碎块进行分类和称量 ,得知当时的地带性植被为油松林和蒙古栎林 ,生态气候为温湿类型 ,同时也存在着气候暖干波动现象 ;柳属的发现说明遗址附近有河流存在 ;根据蒙古栎的起源和生态特性推测这一时期可能有人类的砍伐活动 ;H1出土的油松木炭可能绝大多数属于薪炭遗存     

20世纪中国的社会转型与社会变革的两种思想和方式

在20世纪中国社会转型的过程中,革命与改良(改革)这两种变革思想和方式之间虽然有重大区别,但又是互补的,而且"你中有我,我中有你".两者在不同的历史时期各凸现其主导功能,也会相互转化,不可绝对地厚此薄彼,更不可只肯定一种而否定另一种.事实上,革命与改良是同一部乐曲的"双重变奏",两者的相生相克、相辅相成、交互辉映,共同组成了20世纪中华民族救亡图存、启蒙大众、革故鼎新的历史画卷,共同推进了中国社会的现代化.20世纪最后20多年的改革和发展趋势表明,中国尽管已从根本上摆脱了自我束缚的困扰,但进入新世纪后最需要的是居安思危,力戒盛世意识,增强忧患意识.

Siberia at the Last Glacial Maximum: Environment and Archaeology

This article focuses on the presence of humans in Siberia and the Russian Far East at the coldest time of the Late Pleistocene, called the Last Glacial Maximum (LGM) and dated to c. 20,000–18,000 rcbp. Reconstruction of the LGM environment of Siberia, based on the latest models and compilations, provides a background for human existence in this region. Most of Siberia and the Russian Far East at c. 20,000–18,000 rcbp was covered by tundra and cool steppe, with some forest formations in the river valleys. Climate was much colder and drier than it is today. Eighteen Upper Paleolithic sites in Siberia are radiocarbon dated strictly to the LGM, and at least six of them, located in southern parts of western and eastern Siberia and the Russian Far East, have solid evidence of occupation during that time span. It seems clear that southern Siberia was populated by humans even at the height of the LGM, and that there was no dramatic decline or complete disappearance of humans in Siberia at that time. The degree of human adaptation to periglacial landscapes in the mid-Upper Paleolithic of northern Eurasia was quite high; humans coped with the cold and dry environmental conditions using microblade technology, artificial shelters, tailored clothes, and megafaunal bones as fuel.

商末黄河中游气候环境的变化与社会变迁

新石器时代到商代黄河流域的气候属于温暖湿润期;商代后期气候出现厂干旱化,导致了古公亶父迁岐,文王迁程迁丰,帝乙帝辛时不断向南方发展;而商末的旱灾和饥荒是周武王克商的直接导火索,导致商周之际的改朝换代。商末气候环境的变迁对其时社会政治的影响极大。     

A climate terrorism assemblage? Exploring the politics of climate change-terrorism-radicalisation relations

Despite a series of claims from Bernie Sanders (2015), Barack Obama (2015), and others arguing that climate change, radicalisation, and terrorism are connected by complex causal relationships, there is very little academic examination of the politics of these claims. Building on DeLanda’s (2006) account of assemblages and social complexity, this paper conceptualises climate change-terrorism-radicalisation relationships as a ‘climate terrorism assemblage’. A ‘climate terrorism assemblage’ is a complex, emergent ‘whole’ formed from a heterogeneous range of interacting geopolitical components (e.g. climatic factors, migration, think tanks and academic publications, and a discourse of ‘climate security’). Specifically, a climate terrorism assemblage is characterised by ‘strategic territorialisations’: context-specific, multi-scalar points at which political claims of causal links between climate change, terrorism, and radicalisation are crystallised. Strategic territorialisations are produced in two, interrelated contexts. First, using the case study of the Syrian Conflict, a climate terrorism assemblage reveals an intricate, contested politics of ‘drawing lines’ which link climate change, terrorism, and radicalisation. Secondly, the paper argues that, at the points at which causal links are constructed between climate change, terrorism and radicalisation, a climate terrorism assemblage territorialises around intersectional subject formations, in particular a young masculine subject vulnerable to potential radicalisation and terrorism. Overall, the paper concludes that a climate terrorism assemblage provides a productive analytic frame to investigate the contested power relations of climate change-radicalisation-terrorism connections.
