商末黄河中游气候环境的变化与社会变迁 总被引：21，自引：0，他引：21
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。 相似文献

AbstractExclusively planned tourism destinations, such as all-inclusive resorts, gated resort communities, private cruise liner-owned islands and privatized beaches, have increased over the last few decades. Researchers have analyzed these kinds of tourism environments as enclaves, which are typically driven by external forces and actors, strongly supported by globalization and the current neoliberal market economy. Existing research shows that tourism enclaves are characterized by active border-making, power issues and material and/or symbolic separation from the surrounding socio-cultural realities, leading to weak linkages with host communities and the local economy. Tourism enclaves involve power inequalities, injustices and unsustainable practices that often have serious negative impacts on local socio-economic development. The articles of the special issue focus on tourism enclaves in different theoretical and geographical contexts and they contribute to our understanding of how these exclusive spaces are created and transformed and how they shape places and place identities. The individual research articles are contextualized and discussed with the key theoretical perspectives and empirical findings on tourism enclaves. Future research needs include analysis of linkages and flows of labor, goods, ideas and capital in different scales; policymaking, planning and regulations; environmental impacts; and locals’ land and resource access in the respect of bordering, privatization and land grabbing. By focusing on these topics, the tourism industry could be guided towards more responsible and sustainable development path. 相似文献

Enclosed, controlled environments, stretching from sites of luxury consumption to urban food production, are proliferating in cities around the world, utilising increasingly advanced techniques for (re)creating and optimising microclimatic conditions for different purposes. However, the role of automated control systems—to filter, reprocess and reassemble atmospheric and metabolic flows with growing precision—remains under-researched. In this article, we explore the phenomenon of automated environmental control at three sites in the UK city of Sheffield: a botanical glasshouse, a luxury hotel and a university plant growth research lab. In doing so, we first show how controlled environments are constituted through specific relations between the inside and outside, which are embedded in inherently political urban contexts and processes. Second, we identify the technical and ecological tensions and limits of indoor environmental control at each site which limit the scope of automation, and the considerable amount of hidden labour and energy required to maintain and restabilise desired conditions. Drawing on these more established examples of ecological interiorisation in a key moment of transition, we raise urgent questions for critical urban and environmental geographers about the possible futures of controlled environments, their practical or selective scalability, and who and what will be left “outside”, when they are emerging as a strategic form of urban adaptation and immunisation in the face of converging ecological pressures. 相似文献

Lead isotope compositions provide a direct means of assessing provenance. The lead contents in bronzes cannot be used to argue against lead isotopes. Any claim for the origin of the source material for the origin of Yin‐Shang bronzes must satisfy the measured lead isotope compositions. Thus far, only southern African sources are found to meet this criteria. 相似文献

北宋东京汴河东水门考 总被引：2，自引：0，他引：2
本文综合研究文献记载与考古资料,认为北宋东京汴河东水门应由河道之上的水闸门、汴河南北两岸的陆行门,以及南北拐子城所组成。拐子城,系直门两重,是为了保卫上善与通津两座陆行门和汴河漕运而建,在北宋末年抗击金人的东京保卫战中,起了重要作用。张择端《清明上河图》中所绘制的那座城门,即为汴河南岸的上善门 相似文献
