基于遥感影像及在线房租数据的城市内部贫困空间测度研究——以广州市内城核心区为例

学界以社会经济指标（人口普查、问卷调查等）为主导测度城市内部贫困空间,取得较好的研究成果;但是普查数据周期长、贫困群体社会经济数据可获得性低,如何制定全覆盖、多方位、易获取的测度指标是该项研究的主要挑战之一。本文尝试使用遥感影像、在线房租等公众可获取的数据,采用FETEX2.0、WEKA等软件,利用三个指标（土地覆盖指数、复杂度、单位房租）建构基于大数据的贫困指数,测度广州市内城核心区718个居委会的贫困得分。再将测度结果与利用第六次全国人口普查数据测度的贫困空间对比分析,探究两种测度方法的区别和适用性。结果显示：①两者的测度结果具有较强的一致性,尤其对前5%最贫困的居委会具有较高重合度;②本文建构的大数据贫困指数对城中村、传统工业区等典型贫困空间识别效果更好。本研究使用易获取、更新周期短的数据,有利于城市贫困空间分布的实时监测,对引导精准分配扶贫资源、有效实施贫困社区更新规划具有重要意义。     

市场资本驱动下的乡村空间生产与治理重构——对婺源县Y村的实证观察

乡村振兴不能回避资本,然而资本下乡会改变乡村内部治理结构,如何善用资本以实现乡村善治成为一个难题。文章以江西省婺源县Y村作为典型案例,基于空间生产理论视角,深度剖析资本介入后村庄治理主体的关系转换和资本运行的内在机制,并揭示资本介入后乡村善治面临的难题。文章认为,市场资本介入乡村重构了空间生产主体,并倾向于构建符合自身需求的新空间形态。新空间形态进一步形成了新社会关系网络,新社会关系网络在市场资本的助推下稳固,并逐步将村民主体排挤出村庄,导致资本下乡后空间非正义等问题凸显。未来的乡村治理模式应当发挥资本的触媒作用;维持政府公正性角色,保持乡村空间正义;明确村民主体地位,鼓励村民作为村庄营建的主体;强化集体力量,保持村集体对空间的有效控制权。     

基于手机信令数据的长春市活动空间特征与社区分异研究

居民时空行为成为透视城市空间的重要视角,本文基于手机信令数据研究长春市活动空间及其社区分异,轮廓性的揭示居住空间、就业空间和消费休闲空间的分布规律,从人地互动的过程与格局的视角认识城市空间。研究发现,居住活动对中心城区依赖明显高于就业和消费休闲活动,就业活动呈现多中心连片发展格局,近郊的欧亚卖场和郊区的净月潭成为人们消费休闲活动的重要选择。就业-居住距离和消费休闲-居住距离的社区分异显著,折射出三类活动空间关系复杂,由此感知城市生活空间质量和社会空间结构。通过对社区分异的空间聚类分析明晰各地域自身问题,从而有针对性的对长春的空间调整优化和居民行为引导提出建议,构建和谐宜居的城市空间。     

城市广场:城市制约中的空间政治

现代性的线性时间维度向后现代的空间转向,是一种典型的文化表征。城市广场,作为当代城市生活转向空间存在的\"第二自然\"。它开始成为一种超越空间二元对立模式划分的\"异位空间\",并具有了特定的空间文化意味与空间政治学色彩。即城市广场的空间狂欢、类民主化的自由集市和秩序失序后的再秩序化是其显著的特征。这些都使得城市广场成为一个具有后现代意味的文化空间。     

城市邻避空间及其演变轨迹——以南京市殡葬邻避空间为例

随着我国快速城镇化的进程和城市规模的扩大,多元化的能源设施、废弃物处理设施、社会类设施、特殊交通等邻避设施必将陆续进入城市规划区,并成为城市新的风险,基于公众对不同类型邻避设施风险接受度的差异而形成了不同特征的邻避空间。本文提出了邻避空间的概念,分析了其形成机制、扩散模式和类型,在此基础上以南京市殡葬邻避空间为例,分析其在“产生-挤压-消亡-再生”的空间生命周期中,邻避空间和城市空间之间经历的“侵入-竞争-协调-融合”的互动肌理,由此形成在城市中“边缘-近郊-市区-中心”的空间演变规律及再生手法,理论上丰富了邻避设施风险认知的范式和邻避空间的分析,实践中有利于提高邻避设施在城市中的顺利布局并应对邻避冲突。     

The Gravity of Archaeology

One of the defining features of the material culture of space exploration is the fact that much of it is “out there”: in orbit around celestial bodies and on planetary surfaces. In outer space, we have to rethink the meaning of place. Cartesian coordinates must be replaced with equations of motion to describe the ceaseless movement of heavenly objects in relation to centres of gravity. Archaeological sites in space are not solid condensations of artefacts, hundreds or thousands of years compressed into layers perhaps only centimetres deep. The materials of an archaeological deposit become rather a cloud or swarm. But for both Earth and space, gravity is the structuring force. In this paper I want to reconceptualise archaeological sites according to their position in the gravity well, using dynamical systems and Riemann surfaces. I then consider the Mir space station as an example of a site existing simultaneously on Earth and in orbit, as a preliminary excursion towards a frame of reference that can be used to effectively conduct an archaeology in outer space.     

Developing ethical geography students? The impact and effectiveness of a tutorial-based approach

This paper explores the effectiveness of a tutorial-based approach in supporting the development of geography undergraduates’ ethical thinking. It was found that overall the intervention had a statistically significant impact on students’ ethical thinking scores as assessed using a Meta-Ethical Questionnaire. The initiative led to a convergence of scores, having a bigger impact on those who had a relatively low score prior to the intervention. Interestingly, the approach had the biggest impact on students who self-identified as physical geographers. Unlike some previous research, there was little evidence of difference between male and female students.     

Chronotopes of study abroad: the cultural Other,immersion, and compartmentalized space–time

Study abroad offers a specific configuration of encountering cultural Others: in a demarcated “abroad” space in a compartmentalized time period. Informed by Bakhtin's notion of chronotopes, this article investigates narratives of American college students who studied in Paris, France and Bilbao, Spain in June–July 2011 based on an ethnographic fieldwork of their stay. I identify two chronotopes held in tension in their narratives that reflect tenets of the discourse of immersion: of homogeneous space where every minute students spend in the host society is “local” time full of learning, which risks portraying the host society as frozen in the time of the students’ stay; and of heterogeneous space where local space–time and outsider (e.g. American students and tourists) space–time co-exist hierarchically, where students strive to show their engagement with the former. This article calls for encouraging students to examine the effects of these chronotopes on their experiences and for viewing study abroad not as an encounter of two cultures but as diverse students joining in the ongoing production of heterogeneous host society space with a compartmentalized yet expanding notion of time.
