江南丘陵区农村居民点空间演变特征及影响因素研究——以长沙市为例

以江南丘陵区的长沙市为例,以1989年和2013年的Landsat TM影像及DEM为数据,应用GIS空间分析方法,对长沙市1989-2013年农村居民点空间演变的过程、格局、特征及影响因素进行研究。结果表明:①农村居民点密度不断加大,居民点空间扩展特征显著,但居民点布局较为分散;②农村居民点用地布局低地指向性特征明显,不同地貌类型区的农村居民点地域分异特征较为显著;③农村居民点空间布局的道路和河流指向性特征明显,距离道路与河流越近,农村居民点面积越大,反之则越少;④自然环境决定了长沙市农村居民点总体空间布局,同时,经济发展、农村城镇化与工业化、交通条件、政策制度等因素对农村居民点空间演变具有重要的影响。     

武汉市养老设施空间可达性分析

基于Arcgis平台,以第六次人口普查数据为基础,以乡镇街道为分析单元,采用具有不同有效服务半径的改进的潜能模型对武汉市养老设施空间可达性进行测算。结果表明,改进的潜能模型能合理地评价武汉市养老设施空间可达性,有效判断养老设施稀缺程度;养老设施空间可达性从武汉市东南地区向四周逐渐递减;距市中心越远,乡镇街道养老设施空间可达性越低。文章直观揭示武汉市各乡镇街道养老设施空间可达性差异,有效判别武汉市各乡镇街道养老设施稀缺程度,为养老设施空间配置、优化布局提供科学依据。     

城市混居地段外来人口社会隔离的空间测度——以广州客村为例

本研究选取广州客村代表典型的城市混居地段,创新性地从空间维度测度本地人与外来人群体的社会隔离程度,包括其社交对象的地域分布差异及空间活动轨迹的差异。基于社会学二模网络理论,建立空间共场性的概念,测度两类人群的社会隔离程度。研究发现:客村外来人群体的社交对象具有鲜明的迁出地指向特征;本地人与外来人两类群体的空间活动轨迹呈现显著分异,体现为使用公共服务设施与公共开敞空间的区隔;通过两类群体之间及各自内部的共场度测度,发现外来人群体过于离散的空间活动轨迹不利于其获取社会网络的支持。     

空心村村民居住生活空间特征及其优化重构——对河南邓州市8个村庄的调查

在空心村整治过程中,地方政府普遍重视通过土地整理和迁村并点实现用地集约,而忽视对村庄内部村民居住生活空间的优化。本文以邓州市桑庄镇8个村作为调研区域,对当地村民进行问卷调查和深度访谈,归纳出空心村背景下乡村居住生活空间的形态变化和利用模式,分析其反映出的乡村生活中的矛盾与问题,并在此基础上提出对乡村居住生活空间的重构思路,为空心村整治过程中乡村社区的重建与优化提供参考。     

Neoliberal privatisation? Remapping the public and the private in Sydney's masterplanned residential estates

The analysis of neoliberalism has become a key point of departure in critical urban studies and political geography. Its application in theorising new forms of residential environments is no exception. Common interest developments, gated communities and, in the Australian case, masterplanned residential estates (MPREs) are cast as vehicles of neoliberalist privatisation, extending private property rights and embedding market logics and neoliberal modes of privatised governance. This paper is a critical theoretical and empirical engagement with the interpretation of these residential developments as iconic expressions of urban neoliberalisation. We bring poststructuralist thinking on neoliberalism as an assemblage of diverse practices and projects together with poststructuralist conceptions of the public and private as contextual and enacted political constructions, to provide an alternative analytic—an analytic of assemblage—for investigating putative pathways of neoliberal privatisation. We suggest the purchase of this extended framework through an exploration of MPRE development by Sydney's largest MPRE developer. In this framework, MPREs become contingent productions in which multiple and overdetermined projects, practices and paradigms of governance are at work including, amongst others, social sustainability and interventionism. Rather than producing neoliberal privatisation, we explore how MPRE developments involve the complex constitution of new forms of public and private that exceed coding as neoliberal. We conclude that the framework engaged with here can enable productive advances for urban theorising. Its emphasis on practice, enactment, multiplicity and assemblage can resist a tendency to reify urban neoliberalism and nurture the development of new conceptions and discourses of urban governance less bound to the neoliberal imaginary.     

不同模式下城市郊区居民工作日出行行为的比较研究——基于北京与广州的案例分析

本文选择北京、广州的两个典型社区,分别作为转型期中国城市居住郊区化"政府主导模式"与"市场主导模式"的代表案例,基于两个社区的活动日志调查数据,比较两个社区居民的工作日出行行为,以此探究居住郊区化模式对居民出行行为的影响,在国内已有时间地理学研究基础上进行城市间直接比较研究的尝试。研究发现:政府主导的居住郊区化模式为居民提供了较完善的活动机会与便捷的出行环境,但并没有避免职住空间错位;市场主导的居住郊区化模式无法提供完善的活动机会与良好的出行环境,居民日常活动高度依赖于内城。     

Partnership,Master Planning and State Provision: a Case Study of ‘Actually Existing Neoliberalism’ on the Central Coast of New South Wales

Over the past decade neoliberalism has come to represent the dominant policy discourse and ideology in the majority of western economies. Following the attention given to this phenomenon at a global (and national) scale, there has been a recent rise in interest in its regional implementation and expression and in how these are mediated through the embedded institutional associations of context dependent localities. Using Brenner and Theodore's (2002a) notion of ‘actually existing neoliberalisms’, this paper explores the hybrid nature of the residential property market. Using one of Greater Sydney's fastest growing regions as an example, this paper shows how residential developments are hybrid constructions, framed by institutional and policy resonances constituted by both state and market actants. Key factors here are the processes of partnership (a process of joining the market and the state), master planning (a process of recognising and pursuing the goals of both the market and the state) and negotiation and provision of state infrastructure (a process of direct state construction of the market).     

20世纪90年代以来封闭社区国内外研究述评

全球化与"新自由主义"背景下,封闭社区已经成为当代城市研究的热点问题,本文对20世纪90年代以来的相关文献进行梳理,以多重维度解读封闭社区的形成与发展之动力机制,探讨了全球化与后福特主义、新自由主义公共策略、公共选择与制度经济学、社会隔离与社会冲突、文化权力与空间等五种研究范式。根据市场、权力、居民群体三方力量的消长,可将诸类案例划分为自发推动、资本驱动以及自上而下三种。对于封闭社区与社会隔离的相关性问题,存在社会结构体制与个人行为态度两个层面的争论。在此基础上,本文对国内的相关领域研究提出了建议与展望。     

住房制度改革对中国城市居住分异的影响

住房制度改革是中国城市居住分异的重要影响因素。住房制度改革后,城市居民可根据自身社会经济特征和消费偏好,选择居住区位和住房与邻里质量,住房选择行为相对自由化。商品房的开发在住房制度改革后得到鼓励,房产商在政府宏观调控指引下,自主选择投资区位,建设不同层次的住房和邻里,以满足不同层次居民的居住需求。不同类型企业、不同工龄的职工在享受房改房的机会明显不同,造成享受者和未享受者住房条件的差异,从而形成居住分异。公共部门的干预使得住房类型构成多样化,出现了经济适用房、房改房和廉租房等资助房,与商品房并存;种种约束条件使得社会群体在不同类型住房中分布并不均衡,形成居住分异。     

Residential segregation and inequality: Considering barriers to choice in Toronto

Segregation of visible minorities has persisted throughout time in Toronto. In examining these concentrations, the literature has been heavily focused on the notion that visible minorities are choosing to live in proximity to their respective ethno-racial groups and that these are spaces of aspiration rather than marginalization in Canada. This paper raises questions about the assertion of “self-segregation” by emphasizing affordability constraints on residential choices that are often rooted in discrimination in the labour market. Census data from 2016 and an adopted neighbourhood classification scheme were used to understand the spatial patterning of visible minorities in the Toronto census metropolitan area and highlight differences in the socio-economic characteristics of visible minority dominant and white dominant census tracts. The findings invite the inference that economic opportunities play a critical role in the residential choices of visible minorities and raise concerns about the quality of life in visible minority neighbourhoods. This research contributes to our understanding of how social inequalities have impacted the socio-spatial organization of the city of Toronto.
