本文关注我国边境人口变动和人口流动状况,着重分析了人口流动对边境人口安全的影响机制,并探讨了边境人口流动的影响因素。研究发现,①边境县域人口总体规模稳中略降,人口增速和增量持续减少;②人口净流出已逐步成为边境人口变动主要因素;③边境人口变动与流动影响程度有明显区域差异。外流风险型地区已出现明显的人口负增长和外流,人口安全缺乏数量和质量保障;相对稳定型地区人口保持低速增长,但其人口净流出水平正不断提高,有向外流风险型转变的趋势;相对封闭增长型地区人口增长较快,但流动性较弱。各类边境地区人口流出流入呈现不同特征,并受到经济、教育、城镇化、民族、政策等不同因素影响。  相似文献

中国城乡协调发展空间格局与演化研究   总被引:3,自引:0,他引:3  
本文从三个方面构建了城乡协调发展度指数,对中国2000-2008年31个省城乡协调发展程度的整体变化及在大区上的空间差异进行了评价和原因探讨。结果显示,中国城乡协调发展程度整体呈现上升趋势,主要原因是城乡增长率差异系数的降低,说明我国近些年的支农惠农和统筹城乡发展的政策效果显著。东部和西部地区城乡发展逐步协调,而中部和东北地区城乡发展协调度下降。东部城市和农村基本实现共同富裕,而西部是较低水平上的协调。东北地区先大幅下降后缓慢上升,中部地区的城乡协调发展度目前是最低的,变化较为复杂。  相似文献

我国人口城镇化与土地城镇化协调发展研究   总被引:25,自引:1,他引:24  
中国正处于城镇化进程加速发展时期,城市规模不断扩大,城市数目不断增加,单以非农人口比重这一标准衡量城镇化水平并不能全面反映城镇化的内涵,因此,如何理性评价当前的城镇化状态值得思考。城镇化包含人口向城镇的转型、集中、强化和分异的过程,同样也包括城镇景观的地域推进过程。在归纳总结城镇化的深层内涵的基础上,选择人口城镇化和土地城镇化为切入点,从两个不同的角度衡量我国的城镇化水平,并研究二者协调发展状态。通过时间序列演算,发现人口城镇化指数与土地城镇化指数均呈现持续上升的趋势,并且从2002年开始土地城镇化指数增长速度明显加快,并在2007年土地城镇化指数超过人口城镇化指数;空间分析的结果显示,我国人口城镇化与土地城镇化协调发展空间格局具有水平总体偏低、阶段差距大、区域分异明显等特点。  相似文献

The intercensal period (2006–2011) was a time of significant policy and population change in Indigenous affairs. The aim of this paper is to document the changing distribution of Aboriginal and Torres Strait Islander population and housing geographies over that period. We use the Indigenous Region structure developed by the Australian Bureau of Statistics to show that Indigenous Australians grew at a rate that significantly outstrips the non‐Indigenous population with an increasing concentration of the Indigenous population on the urban eastern seaboard and particularly among older people. We present results that show that for certain measures, the housing situation of the Indigenous population in 2011 had improved relative to the Indigenous population in 2006. A smaller proportion of Indigenous households were estimated to live in an overcrowded dwelling compared with Indigenous households in 2006. There were also significant increases in the per cent of Indigenous households that owned or were purchasing their own home. Other results might be seen as less positive with community housing (a tenure type identified as having benefits in both qualitative and quantitative analysis) declining in importance. In net terms though, Indigenous households continue to experience a high degree of housing need. Compared with other households, they were 3.7 times as likely to live in an overcrowded dwelling.  相似文献

Sustainable development as a process towards sustainability requires collaboration among societal actors and stakeholders at multiple levels. A key issue is to provide them with that they have comprehensive and transparent knowledge base representing the state and trends of different dimensions of sustainability. This study addresses the need to analyse and present data of sustainability as a foundation for the sustainable development process within municipalities, and among them. As a case study, we focus on 18 municipalities in the crisis-struck Bergslagen region in Sweden and compare them with 101 surrounding municipalities. Data from 2001 and 2006 on 15 indicators representing ecological, economic and social sustainability criteria were transformed to a common scale through normalization around the median, and summarized. Bergslagen region municipalities performed poorer than the surrounding ones for all dimensions in 2006. The change from 2001 to 2006 was positive for economic and social criteria, while the ecological dimension developed negatively in all municipalities. We stress the need for municipalities to collaborate with each other and other actors both at municipal and regional levels, and to use sustainability indicators as a base for informed planning processes. We propose visualization of indicators using maps to support decision-making and social learning.  相似文献

In seeking to explain why and how the war in Afghanistan has dragged on, most analysis has focused on the western and Afghan government effort. In this article, we examine how the war looks from the perspective of the insurgency. Using Helmand province as a case‐study, we draw on a large number of original interviews with Taliban field commanders and fighters to produce a uniquely detailed picture of the Taliban at war. In the first section, we explore how the Taliban returned to Helmand from 2004 to 2006, and show how the British made the situation far worse when they deployed forces to Helmand in 2006. In the second part of the article we examine the evolution of the Taliban insurgency in Helmand since 2006. We show how the Taliban has developed an increasingly centralized organizational structure, a more militarized shadow government and greater professionalism of field units. The overall picture that emerges is of a resilient insurgency that has adapted under immense military pressure. The Taliban have suffered very heavy attrition in Helmand, but they are far from defeated.  相似文献

This article has been developed and updated from a paper delivered at the Grossbritannien-Zentrum, Humboldt University at Berlin, June 2000. Traditionally, sport has been marginalized, even treated as an irrelevance, in the study of International Relations (IR). The 2002 World Cup Finals raised yet again questions about the realism of continuing to write sport out of IR, and particularly to ignore its impact upon such relationships as those between Britain and Germany. Football's role in mirroring, influencing and articulating British perceptions of Germany, at least at the popular and media level, is presented as a case-study, since the football field proved another important British_German battleground throughout the twentieth century. This trend continues. Already, three high profile football internationals played during 2000–1 as well as rivalry to host the 2006 World Cup tournament have illuminated the problematic state of the British-German relationship, particularly the fact that history, most notably world war imagery, imparts en enduring extra-sporting sub-text for any England-Germany footballing encounter.  相似文献

This study examines the relationship between China’s contraception policy and married women’s (20–49 years) choice between long-acting and short-acting contraceptive methods during two periods–1980–1994 and 1995–2012. The aim is to examine the link between strictness of the contraception policy and married women’s contraceptive choice. Using data from the 1988 and the 2006 National Family Planning and Reproductive Health Surveys, we estimated the effect of contraception policy in the tightened and the loosened policy periods using a permutation test. The results show that while contraception policy promoted long-acting contraceptive methods, many married women themselves preferred short-acting contraceptive methods. During the tightened policy period, we found married women on average were 2.7 times more likely to use long-acting methods. The effect was only 1.7 times during the loosened policy period. The effect was also parity dependent. The more stringent the contraception policy was, the more likely married women used a long-acting contraceptive method. This study provides the first ever proper estimation of China’s contraception policy effects during the two periods.  相似文献

Tuberculosis has existed from early prehistoric days to modern times. The main causative agents of tuberculosis worldwide are Mycobacterium tuberculosis (M. tuberculosis) and M. bovis, along with M. africanum, M. cenettii and M. microti; these species make up the ‘M. tuberculosis complex’. This worldwide infection has been of special interest to palaeopathologists due to its characteristic bone lesions as well as its great antiquity. Historically, tuberculosis has been recognised in Japan for more than a thousand years. However, the origin and early prevalence of tuberculosis remain unknown. In the present study, we present the earliest evidence of skeletal tuberculosis found in the Aneolithic Yayoi period in Japan (ca. 300 BC to AD 300). The skeletal remains showing typical pathological changes of spinal tuberculosis were dated to between 454 BC and AD 124 by dendrochronological methods using coburied arrow-shield board and house columns made of Japanese cedar. We discuss the early prevalence of this infectious disease and its influence on the population history of the Japanese from prehistoric to Aneolithic times.

文章以深圳市平湖镇为例,通过实地考察和典型调查,对大城市外围地区流动人口的结构及其城镇建设用地使用特征进行研究。发现平湖的流动人口结构较为简单,大多数是来自我国西南落后地区青壮年农村剩余劳动力,并且以务工和经商为主。由于其从业特征的差异,务工和经商人员分别集中在城镇工业区和商业区内,人口分布密度较高,人均建设用地面积严重偏低。文章认为在大城市外围地区的城市规划中必须加强对流动人口的用地需求研究,以解决大规模的流动人口与相对紧缺的城镇用地之间的矛盾,并且进一步做了平湖流动人口用地需求分析,提出其规划调整建议。  相似文献

人口统计数据空间化是解决统计数据与自然要素数据融合分析的有效途径。随着RS和GIS技术的发展,人口空间化方法推陈出新,但不同的方法各有优缺点,方法选择和精度保证是两个重要的问题。本文以黄河三角洲高效生态经济区2010年县(市、区)单元人口统计信息为案例,分别基于土地利用数据和夜间灯光数据建立1km栅格的人口空间化模型,再分别以县(市、区)和乡(镇、街道办)为验证单元,比较两种方法模拟人口分布的优缺点。结果表明,基于土地利用数据的人口空间化模型整体优于基于夜间灯光数据的人口空间化模型,且前者更适合于模拟人口总数居中的县(市、区),后者在人口密度梯度较大的城镇边缘有更好的模拟效果,在人口较少的地区二者的模拟效果均不太理想。本研究能够为获取高精度的区域人口空间化模型提供参考。  相似文献
