Istanbul’s Taksim Square has long been a place from which people have envisioned the city and the nation. As such, it has a long history of architectural interventions. This essay describes three new interventions as they appeared in July2018, two years after the failed coup attempt of 15July2016: a municipal complex commemorating the resistance to the coup attempt; the juxtaposition of a memorial photo exhibit and the void of the Atatürk Culture Center; and the rapid construction of the Taksim Mosque. Drawing on conceptualizations of landscape and scholarship on Taksim Square’s contested meanings, this paper utilizes the “politics of perspective” as an analytical lens to examine how authorities are attempting to create anew way of seeing in the city. I argue that this project has acquired a new character in the aftermath of the coup attempt, placing viewers within the landscape rather than outside it.  相似文献

北极阿拉斯加北坡盆地是全球开展天然气水合物的调查研究最早的地区之一,对全球天然气水合物的研究具有示范作用。在大量文献资料综合分析的基础上,本文系统归纳了阿拉斯加北坡地区天然气水合物的成矿地质条件和成矿规律。认为阿拉斯加北坡的天然气水合物成矿系统是下伏下白垩第三系含油气系统在浅部的衍生,是由下伏气源、断裂、岩性、北极的特殊环境(永久冻土、地层温压场)等多种因素共同作用的结果。通过模拟计算和分析,将阿拉斯加北坡地区划分了3级远景资源区,估算出整个阿拉斯加地区的天然气水合物资源为6.0×10^12 m^3标准天然气,其中I级远景区主要分布于阿拉斯加北坡的滨岸冻土区和陆架区,资源量为2.83×10^12 m^3标准天然气。  相似文献

In accepting that Aotearoa is no-longer a rural nation there are exciting possibilities for the study of urban socio-cultural geography - the effects of urbanisation on the lives ofNewZealanders. Contemporary social geographical theories have combined with postmodernism, poststructuralism, postcolonialism and feminism toproducea ‘new cultural geography’. We argue that this new cultural geography couldprovide important theoretical avenues for the development of an ‘indigenous’ New Zealand urban socio-cultural geography.  相似文献

在对新疆县域经济发展评价基础上,分析了新疆县域经济分异的特征,探讨了经济分异的原因,提出了解决对策。新疆县域经济差异的空间分异、民族分异在很大程度上叠加为民族经济发展水平的空间分异。新疆县域经济分异与国家安全形势长期面临威胁时的经济建设投入差异、各民族就业人员比例差异、各民族人口的就业行业差异及各民族人口空间分布有关。应当增加对新疆特别是疆内落后县域的固定资产投资,并努力使经济增长与就业增长协调起来;增加基础教育投资,同时加大职业技术教育;鼓励实行少数民族人口一对夫妇生育两个子女的政策,以减轻家庭负担,提高学生入学比例,才能大力迅速提升少数民族人口素质。只有这样,才能协调好各民族、各县域经济的发展,有利于国家稳定发展。  相似文献

Grain production patterns are the basis of a nation’s food security. Since China’s reform and opening-up began in 1978, China’s urbanization process, driven by rapid social and economic development, has accelerated steadily. During this time, the dietary structure of urban and rural Chinese has also changed significantly. Accordingly, grain production patterns have undergone major changes. First, traditional grain production patterns in the north and the south have changed, and the food production center has shifted toward the north. In 1980, the grain yield of southern provinces accounted for 60% of China’s total, while that of northern provinces accounted for 40%. In 2015, the grain yield of southern provinces accounted for 56% of the total, while that of northern provinces accounted for 44%. Second, grain production by regions of the country is “shrinking in the east but expanding in the central regions,” meaning that grain production in eastern coastal provinces has decreased significantly, while that in the central region has expanded. The proportions of the nation’s total grain production from the eastern, central and western regions were 38%, 36% and 26%, respectively, in 1980. These had changed to 27%, 46%, and 27%, respectively, in 2015. Third, the spatial centralization of grain production has increased. The total grain yield of 13 major grain-producing provinces and regions in the country accounted for 69.27% of nation’s total in 1980, and it had reached 76.18% in 2015, showing that the impact of major grain-producing areas on national food security has increased. The influence of rapid urbanization on grain production areas shows remarkable regional differences. As the level of urbanization has increased, build-up land occupies a large number of high-quality farmland, especially in east coastal provinces and thus the grain planting area decreased obviously. The effect of dietary structure changes on grain production patterns was evident in two ways. On the one hand, as dietary diversity has increased, total grain consumption has decreased. The reduction in the proportion of planting area for grain crops to total crop planting area dropped from 82% in 1980 to 68% in 2015, making this change in total grain consumption evident. On the other hand, the ratio of grain for human consumption declined as the ratio of grain consumed by animals increased. The reduction in the proportion of rice and wheat grown and an increase in the proportion of feed grain production (mostly maize) from 20% in the 1980s to 36% in 2015 makes this change in grain production and consumption evident. In the future, with the establishment of national functional areas for grain production, the spatial pattern of grain production will return, while the demand for feed grains will continue to increase but with the space for expansion limited.  相似文献

济宁市相对资源承载力与可持续发展   总被引:3,自引:0,他引:3  
自然资源、经济资源对一个国家或地区的人口起重要的支撑作用,是可持续发展的基础。本文在界定相对资源承载力概念的基础上,采用相对资源承载力的研究方法,以济宁市为研究区,以山东省为参照区,计算分析了1996-2008年济宁市相对自然资源承载力、相对经济资源承载力和综合承载力。结果表明:①济宁市各项资源承载力都处于超载状态;②济宁市自然资源对综合承载力的贡献率占较高比例,是人口的主要承载资源。在此基础上,指出济宁市实现可持续发展存在的相对综合承载力下降、耕地面积减少、煤炭依赖症、三大产业结构不合理等问题,分析了济宁市实现可持续发展具有的平原面积大、矿产资源丰富和旅游资源得天独厚的竞争优势。  相似文献

随着中国城市住房价格大幅上涨,住房可支付性成为青年面临的严峻挑战。尽管越来越多的研究开始关注中国城市住房不平等问题,但大多侧重住房资源分配由国家向市场的转移,相对而言,家庭在住房资源获取中的作用被忽视。本文选取上海市作为研究区域,使用2013年长三角社会变迁调查数据,以上海“80后”青年家庭为研究对象,重点关注夫妻双方父母的住房状况和社会经济属性对青年家庭住房产权获得的影响及性别差异。研究发现,父母户口很大程度上影响着青年家庭的住房结果;不同户口状况的父母住房财富存在较大分化,其影响着年轻家庭可获得的家庭购房资助的数额。与妻子父母相比,丈夫父母的户口状况对青年家庭住房结果的影响更大;而妻子父母在本地且拥有住房产权的双重优势与青年家庭住房产权获得有更强的正向联系。家庭背景对子代住房的影响结合婚姻匹配机制使住房优势或劣势在青年家庭内部累积,或会加剧住房分化现象。  相似文献

The first decade of the twenty-first century was one of the most prosperous in Australia's history. The boom was led by a buoyant minerals and energy resource sector, contributing to high levels of economic growth, rising real wages and low unemployment. Yet, as with the nation's previous resources booms, there were marginal transformations in the economies of those regions from which the minerals were extracted. Overwhelmingly, the wealth generated by the resource boom has concentrated in the cities. Moreover, public expenditure in resource regions also remains comparatively low, and indeed tend to reproduce a development framework oriented towards extraction rather than diversification. This paper employs elements of Innis' staples thesis to help explain this pattern of regional development, and in particular the relatively low levels of reinvestment in resource peripheries. Drawing on the notion of a 'resource bank', we contend that resource regions are often viewed as a reserve of latent wealth that can be drawn upon for the benefit of the urban 'core'. Yet, we also highlight emerging strategies aimed at overcoming this and that seek to return a greater proportion of wealth to those regions from which it was extracted.  相似文献

County scale cartographic analysis of Ronald Reagan's reelection landslide of 1984 shows the geographical core of his electoral strength to be in the Interior West, non-ethnic areas of the South, and suburbs across the nation. Examination of spatio-temporal variations using factor analysis at a state scale shows this to be a continuation and reinforcement of recent electoral-geographical cleavages. T-mode factor analysis traces the emergence of a contemporary Conservative Normal Vote during the past several presidential elections and the manifestation of this cleavage in the election of 1984.  相似文献

当前世界地缘政治经济格局发生深刻变化,全球化发展正面临重大挑战。在此背景下,建设海南自由贸易港既是中国深化改革开放的需要,也是在全球治理语境下中国积极重塑地缘政治经济格局的重要举措。以海南自贸港为对象,采用话语分析和网络民族志方法,探讨基于国家品牌的地缘政治实践,审视政府、媒体和国内外普通受众如何参与海南自贸港地理意义的(再)生产,并讨论了其背后的地缘政治运作机制。研究发现,国家品牌建设涉及国家、媒体和普通受众之间的互动,政府利用媒体工具构建宏大叙事,塑造国内外受众对海南自贸港的地理想象,进而支持和强化中国作为全球治理的建设者身份。然而,不同社会文化背景的受众群体形成了差异化的情感体验,普通受众对海南自贸港的认同等积极感知支持了国家身份叙事,质疑和感到威胁等情感则对自上而下和由内而外的话语营建提出挑战。不同行动者的建构和表征作用使国家品牌意义不断被想象、表达和重塑,导致基于国家品牌的地缘政治运作复杂化。  相似文献

区域产业集聚研究进展   总被引:13,自引:3,他引:10  
马延吉 《地理科学》2005,25(2):226-232
区域产业集聚研究是人文地理学重要的研究领域,是人地关系地域系统研究的重要方面,在全球化背景下,区域发展要响应全球化,促进区域产业集聚形成,培育区域发展优势,提高竞争力,融入到全球生产网络。文章重点回顾了近10年来区域产业集聚的研究进展。区域产业集聚的理论研究取得了很大进展,集中体现在新产业区理论、新经济地理学理论、产业簇群理论、点-轴理论、公司地理论等方面。学者们从不同侧面,对区域产业集聚机制进行了研究,注重集聚经济、贸易与市场拉动、企业联系、知识传播等方面的研究。区域产业集聚研究是对全球经济一体化的重要响应,区域企业集群与推进企业的培育是区域产业集聚的关键。要不断调整区域产业集聚要素,以形成产业集聚的最佳状态和效果,要加强传统工业基地的产业集聚研究。既要培育合理的产业集聚,又要注重与区域人口、资源环境相协调。  相似文献
