This paper offers a prospectus for a version of historical geography that puts the seas and oceans at the centre of its concerns. This is pursued in three ways. First, via a discussion of the epistemological and historiographic perspectives that might be taken on geographies of the sea, which argues that the view from the ocean can develop geographies of spaces beyond the local and the national, and can attend to the relationships between the human and natural worlds. Second, through a consideration of the imaginative, aesthetic and sensuous geographies of the sea that contends that maritime worlds open up new experiential dimensions and new forms of representation. Finally, in a survey of the material and social worlds of the oceans that suggests that new life can thereby be breathed into current concerns with global political economy, material geographies, the relationship between knowledge and located practice, and the intersections of social and spatial difference. The paper also provides an introduction to a special issue on the historical geography of the sea.  相似文献

The interactions of nature and society are intimately reflected in the degradation of the vast, yet diverse, landscapes and ecosystems of arid western China. The development of agriculture, especially irrigation, has altered rivers, soils and ecosystems so much that major ecological rehabilitation and restoration efforts have been needed since 1950. The catchments of the Tarim River in southern Xinjiang (the Tarim Basin) and of the Black River (Hei He) in Gansu Province and western Inner Mongolia provide examples of the benefits, difficulties and conflicts involved in dryland water management. In the early stages of the human development of these catchments, agriculture depending on irrigation using water from these inland rivers was encouraged. The over‐exploitation of these water resources led to such ecological problems as desiccation of lakes, drying out of rivers, degradation of soils and vegetation and lowering of groundwater levels, with consequent environmental and economic impacts. Since 1990 several high‐cost, national projects to re‐establish ecosystems have been initiated. Water is now released from dams in the headwaters of the rivers in order to restore water flows to the dried out lake basins. Such schemes have inevitably led to social problems and difficulties for the people who depended on the water from the dams for local irrigation. The contrasts in adjustments and attitudes over the use of water for agriculture and other economic activities, as opposed to schemes of restoration of ecosystems and ecological engineering, stem largely from two issues; inconsistent provision of information from the scientific community, and differing ideologies, namely environmental protection versus economic development.  相似文献

The notion of a superior “civilisation” has been a hallmark of the politics of Western institutions and fringe white supremacists alike. Known ideologically as “civilisationism”, it has occupied a prominent position in the ideology of the Australian far-right. Paying tribute to their settler-colonial origins, the far-right has consistently promoted “white civilisation”, even inspiring terrorist attacks. Despite this propensity for violence, far-right civilisationism remains largely unexplored. Through investigating a dataset of Australian far-right content, this paper reveals civilisationism as a significant part of their ideology, an ideology which relies on the idealisation of European technologies and environments to render Indigenous land and people uncivilised. A critical narrative analysis of the data illustrates the ways that these ecological factors are drawn into narrative to articulate Australian far-right civilisationism, an ideology inseparable from the political ecology of European history and colonialism, that today represents a particularly virulent version of its legacy.  相似文献

我国现存大量的以水泥为基本材料的近现代历史建筑,很多建筑既具有西方建筑美学特征,又融合了中国传统建筑的艺术形态,具有不可替代的历史意义和艺术价值。在长时间的自然和人为因素的影响下,这些建筑都普遍存在内部结构疏松、强度低的状况,保护这些水泥历史建筑已经成为文物保护工作者一项非常迫切的任务。在水分的长期作用下,水泥内部的微孔结构会由于钙质流失而遭到破坏,产生水泥的酥化现象。为加固保护这类历史建筑,本研究合成了一种亲水性高拉伸的有机硅材料。研究表明,该材料能在不明显改变水泥样品表面外观的前提下实现对酥化水泥样品的加固,经有机硅最佳浓度2%加固后的水泥样品的抗压强度可以提升约1倍。同时,这种加固材料在前期施工阶段具有良好的渗透性,加固剂固化后能够有效填补酥化水泥样品中的较大孔隙,从而达到增加强度的效果。另外,这种加固剂具有亲水性的特征,一方面不会存在强憎水性保护剂所带来的保护性破坏,另一方面在大面积现场施工时不需要使用大量有机溶剂,从而避免其对环境和人体的伤害。本研究对于进一步探索和开发水泥历史建筑的加固材料具有重要的借鉴意义。  相似文献

生态税收是政府通过对破坏生态环境的行为(生产行为和消费行为)征收相应数量的税收,用于环境保护的投资或对保护环境的行为的税收支出,以保持生态平衡的一种税收体系。中国日趋严峻的生态环境、生态税制的缺位、可持续发展战略的实现以及提高公民环保意识迫切要求构建我国的生态税收体系。因此,制定完备的《生态税法》;改革旧税种,创立新税种完善税收体系;奖惩并重、税收征收与支出并举,就成为构建我国生态税制的基本思路。  相似文献

The current project is a study of craniofacial trauma in a large sample (n = 896) of Prehispanic Canary Islanders (PCIs). The possible causes and social implications of the trauma found are considered, with reference to archaeological and historical data. Variables include the island, period and ecology, the sex and age of the individuals, the distribution of lesions across the skull (by side and by individual bone) and ante‐mortem tooth loss. The results show a fairly high trauma rate (16%), a low prevalence of peri‐mortem trauma (3.8% of all lesions), higher prevalence of trauma in males than in females (25% vs. 13% of all individuals), more cranial than facial lesions (8.9% vs. 3.5% of all elements) and more lesions on the left side of the skull (6.7% vs. 4.5% of all elements) which suggests that the lesions were sustained through intentional rather than accidental agency. There was no correspondence between trauma prevalence and ecology. The archaeological and historical data support the assertion that the lesions may be the result of skirmishing between groups, using weapons such as slingshots, stones and staves. The presence of edged‐weapon lesions on some individuals suggests that these may have been the victims of contact‐period European groups. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献
