广州市保障性住房社区居民的居住-就业选择与空间匹配性   总被引：8，自引：2，他引：6  

周素红  程璐萍  吴志东 《地理研究》2010,29(10):1735-1745

从居住-就业区位选择角度出发,以广州市典型保障性住房社区(棠下小区、同德小区)为案例,研究保障性住房居民的居住－就业选择特征及其空间匹配性的群体差异和影响机制。经过十多年的发展,研究小区发生明显的居住人群过滤现象,出现大量转售和转租情况,形成保障性住房、商品房、转租房、原单位房的住户结构。保障性住房住户和商品房住户的居住与就业地的空间关系变化较大,其空间不匹配问题突出,但二者在形成机制上存在较大差异。前者主要因保障性住房供应的政策性因素,使其住户的区位选择与主要就业场所不匹配而引发的,属于被动迁移型空间不匹配现象;后者主要是购买转售的保障性住房的住户,为获取保障性住房的政策性福利而通过市场方式选择远离其就业场所空间而引发的,属于主动选择型空间不匹配现象。私人转租房住户和原单位房住户的居住－就业空间匹配性良好。保障性住房的转租和转售在一定程度上产生了政策性福利的再分配,存在一定的不公平性;同时,居住－就业空间不匹配对相关居民的生活质量也带来一定的影响。因此,需要进一步研究保障性住房合理的空间布局方案和实施途径,优化城市空间结构,在考虑社会公平的前提下尽量解决各类群体的居住与就业问题。  相似文献

对玉树地震序列自2010年4月11日至9月15日由台网记录到的1 832个地震采用双差地震定位法进行重新定位,获得了1 670个地震重新定位的震源参数。重新定位后的震源深度主要分布在15 km以内。重新定位后的Ms 7.1级主震发生在无地表破裂段,余震活动向两侧破裂扩展。余震沿地表破裂带基本呈线性分布,剖面上显示为近垂直的结构面,在北西端无地表破裂出露处,出现近垂直于断裂方向较宽的北东向地震密集带。震源机制解显示的主压应力方向斜交地表破裂带,地表破裂与震源破裂都表现为纯左旋走滑的错动性质,而在北西端主压应力方向偏转为近垂直于断裂带的方向,此处较宽的北东向地震密集带可能由近东西与南北两个方向的共轭破裂所组成。余震的后期活动与发展并不局限于主震形成的破裂带内,更多的受局部应力调整被触发而产生新的破裂。  相似文献

INDUSTRIAL INERTIA VERSUS RELOCATION: A SHIPBUILDING ILLUSTRATION     

Daniel Todd 《The Professional geographer》1983,35(3):286-298

Industrial inertia has both spatial and behavioral connotations. In the first place, it implies stability in plant location whereas in the second, it results from managerial behavior which either actively perceives advantages from status quo locations or passively condones such locations through lack of initiative. This paper illustrates the dilemmas facing a British shipbuilding firm which chose to locate at a greenfield site instead of opting for the traditional centers.  相似文献   

中国西北地区台站迁移对气候资料均一性影响的研究进展     

韩海涛  王雅萍  张瑾 《高原气象》2021,40(2):448-454

随着全球变暖的趋势越来越明显,气候变化研究也成为最受关注的问题。均一化长序列数据是气候变化研究的基础。然而由于台站的迁移等因素,导致了资料序列中的非均一性,这种包含非气候因素变化的非均一性气候序列直接影响了气候研究的不确定性。本文在综述国内外地面气候资料均一性检验方法、地面气候资料非均一性产生的原因等进展的基础上,重点分析了中国西北地区台站迁移对气候资料均一性的影响,认为台站迁移是造成气候资料不均一性的主要因素之一,使研究结果不能正确反映气候的变化趋势;国外成熟的均一性检验和订正方法为我国西北地区地面台站迁移对气候资料均一性的影响研究提供了可借鉴的思路、方法和手段;以往关于我国西北部地区气候变化的研究较少考虑气候序列中存在的非均一问题,造成了研究结论的不确定性。因此有必要对我国西北地区经过台站迁移的台站进行均一化的检验和订正。  相似文献   

祁连山中东段地区断层构造和构造变形特征研究     

周琳  李长军  李君  庄文泉 《大地测量与地球动力学》2022,42(6):565-568

基于中小地震重新定位结果和震源区应力场等地球物理资料,分析祁连山中东段地区断层构造和构造变形特征。结果表明：1）祁连山中东段地区震源深度主要分布于2~20 km。龙首山断裂震源深度分布呈上宽下窄的倒三角形;门源6.4级地震的余震震源深度为5~15 km,倾向SW;金强河断裂东段地震活动性强,倾向NE,倾角较高;老虎山断裂东段地震活动性强,倾向NE,深部呈近垂直产状。祁连山中东段地区震源深度自西向东递增,推测祁连山东段地区更深部可能已发生构造活动。2）研究区主压应力方向为NE-NEE向。3）沿祁连山中东段地区一系列走滑断裂与前缘逆冲断裂的组合破裂是青藏高原北东向挤出的一种重要的构造变形调节模式。  相似文献   

基于手机信令数据的城内迁居活跃度识别方法研究——以武汉市为例     

牛强  盛富斌  刘晓阳  严雪心 《地理研究》2022,41(8):2142-2154

中国城市的快速发展加速了城市内部人口的居住迁移,精细测度居民迁居行为及其空间分异特征,对于从人的行为视角来分析城市居住空间结构演进过程具有现实意义。本文以武汉都市发展区为例,基于手机信令大数据,提出净活跃度指标和总活跃度指标来量化描述迁居活跃度,并依据两个指标的分类及组合,将居民居住地划分为高迁入型活跃区、平稳型活跃区、高迁出型活跃区、高迁入型非活跃区、平稳型非活跃区与高迁出型非活跃区六种空间类型,进而探讨居民迁居的空间分布特征。结果表明：① 武汉都市发展区内部人口迁移总体呈现出从主城区向近郊区逐步迁移的趋势,且主城区人口总活跃度相较更高。② 主城区以高迁出型活跃区和高迁入型活跃区为主,近郊区则以平稳型非活跃区为主。③ 不同空间类型内的居住类型存在差异：高迁入型活跃区内以新建小区、高校住区、学区房、城中村为主;平稳型活跃区以农村居住地、园区周边住宅为主;高迁出型活跃区以老旧小区、园区周边住宅、城中村、农村居住地为主;非活跃区则以农村居住地为主。本文提出了一种基于时序手机信令大数据的居民迁居活跃度评价指标体系,并以实证研究证明其对于居民迁居地空间类型划分的有效性,研究结果可为相关规划决策部门掌控城市内部的人口迁移特征提供数据支撑、为城市不同区域针对性的进行公共资源配置提供参考依据。  相似文献   

The Impacts of Relocation on the Livelihoods among Different Agro-pastoralist Groups in an Immigrated Village in Tibet     

ZHU Jin  PAN Ying  ZHAO Zhongxu  LI Zhennan  WU Junxi 《资源与生态学报(英文版)》2022,13(5):888-896

China has achieved a comprehensive victory in poverty eradication. Relocation has been the major measure of the poverty alleviation strategy, and 10 million poor people have successfully been relocated in the ‘Thirteenth Five-Year’ period (from 2016 to 2020). This paper established an integrated evaluation index system for the livelihoods of relocated groups and the sustainability of the village, based on the framework of United Nation 2030 Sustainable Development Goals and using the data from questionnaire surveys in Bailang Village, Tibet. The indicator system quantitatively analyzed the changes in the livelihoods of different agro-pastoralist groups before and after relocation from the three aspects of living standards, livelihood assets, and livelihood strategies. The results showed that relocation led to the improvement of the livelihoods of immigrated households. As the duration after relocation increases, the living standards rise steadily, especially in poverty eradication (SDG1), which increased nearly 100%. Relocation affects the livelihood strategies of the relocated groups, in that the original pure farmers chose more diverse livelihood strategies and the non-farm employment ratio (SDG8) of the village increased. The total SDG score increased from the perspective of the sustainable development of the village. The data also showed that relocation had limited impacts on the livelihoods of the aborigines. The results implied that the relocation policy for poverty alleviation has been implemented successfully in this area. This research could support policy optimization for improving the sustainability of the village and the livelihoods of the immigrants.  相似文献   

Effects of Industrial Relocation on Chinese Regional Economic Growth Disparities: Based on System Dynamics Modeling     

WU Aizhi  LI Guoping  SUN Tieshan  LIANG Yusheng 《中国地理科学(英文版)》2014,(6):706-716

The economic growth of China has led to increasing growth disparities between regions. Such disparities are uncontrolled and are severely negative symptoms in the process of economic development. On the basis of system dynamics （SD） modeling and the rela- tionship between industrial relocation and regional economic growth, we construct a model of the interrelationship between the two aforementioned phenomena. The model is an effective and creative exploration for examining effects of industrial relocation on Chinese regional economic growth disparities. The SD model is employed in this study to build an inter-regional labor migration SD model, an inter-regional capital migration SD model, an intra-industry SD model, an intra-regional population SD model, and an intra-regional SD model which are based on realities in labor and capital flow from the view of industrial relocation. VENSIM software is utilized to per- form a system simulation based on the data of the eastern, middle, and western regions from 2000 to 2010. Results show that indus- trial relocation gradually narrows the relative disparity in GDP among the three regions. Moreover, the absolute one is enlarged con- tinuously. The absolute and relative disparities in per capita GDP among eastern, middle, and western regions generally exhibit de- creasing trends.  相似文献   

企业空间动态研究进展   总被引：6，自引：2，他引：4  

史进  贺灿飞 《地理科学进展》2014,33(10)

企业空间动态从微观视角研究区域产业活动的空间分布及其变化.本文以西方经济地理学哲学基础和方法论转换为背景,梳理了企业空间动态研究的4个理论框架,即新古典框架、行为框架、制度框架和演化框架,探讨了不同框架下企业空间动态的影响因素;在此基础上,分析了现有研究在理论、数据和方法上的问题,并提出了未来研究的展望.与国外丰富的理论与实证研究相比,中国的企业进入、退出和迁移研究主要是在经济学领域,人文-经济地理学虽在企业迁移研究方面取得了一定成果,但在企业进入与退出研究方面尚处于起步阶段.借鉴西方理论时必须注意到中国的政治体制、社会意识形态和经济转型背景,开展本土化的研究.  相似文献
