商业化背景下古村落旅游景观生产 ——以安徽宏村为例

以安徽省古村落宏村为例,采用参与式观察和半结构访谈的方法对其旅游景观的生产方式与机制进行研究。结果发现,随着商业化发展,宏村旅游景观生产由原来单一的文物古建保护向更趋复杂化转变,针对3种不同类型的旅游景观采取相应的生产方式。宏村旅游景观生产背后是多种力量参与的生产机制：政府与开发商强强联合,是旅游景观生产的主导力量;当地居民依然扎根宏村,是旅游景观生产的核心灵魂;景区商家热衷于打造“店铺景观”,是旅游景观生产的积极分子;外来游客提出的改进建议则是宏村旅游景观生产的重要参考。4种力量集团本着对各自利益的谋求,彼此间相互合作,影响宏村旅游景观生产的最终结果。最后提出,古村落旅游景观生产需要还原原住居民生活化场景,借旅游商业化发展之势,建立均衡、可持续的景观生产机制与合理的利益分配体系或许是古村落旅游景观生产的正解。     

Crowdsourcing a cyclist perspective on suggested recreational paths in real-world networks

ABSTRACT

Routing and navigation services for leisure activities are conditioned by special needs and trade-offs. The advent of online communities and large crowdsourced datasets offers opportunities to improve the adoption of a user’s perspective in these suggested paths. This paper focuses on achieving two goals. First, the presented methodology analyses a dataset of 190,610 historical GPS traces to gain insights into the appreciation or attractiveness of each edge in a real-world network for a specific leisure activity (i.e. road cycling). Second, as literature on these leisure activities is still sparse, we want to create a thorough understanding of the activities at hand for future work. An appreciation model is proposed and the spread of this score is analyzed in shortest-path alternatives of popular routing engines for this activity. This analysis successfully discriminates these shortest paths based on the scoring value and three morphological parameters of the path. However, the robustness of the model should be improved to ensure the viability of the proposed approach in future work. More specifically, further research on the local optimality of the route choices will be imperative.     

Community Recovery Following the Deepwater Horizon Oil Spill: Toward a Theory of Cultural Resilience

Culture plays an important role in communities’ abilities to adapt to environmental change and crises. The emerging field of resilience thinking has made several efforts to better integrate social and cultural factors into the systems-level approach to understanding social–ecological resilience. However, attempts to integrate culture into structural models often fail to account for the agentic processes that influence recovery at the individual and community levels, overshadowing the potential for agency and variation in community response. Using empirical data on the 2010 BP oil spill’s impact on a small, natural-resource-dependent community, we propose an alternative approach emphasizing culture’s ability to operate as a resource that contributes to social, or community, resilience. We refer to this more explicit articulation of culture’s role in resilience as cultural resilience. Our findings reveal that not all cultural resources that define resilience in reference to certain disasters provided successful mitigation, adaptation, or recovery from the BP spill.     

Exploring Cities through a Population Ageing Matrix: a spatial and temporal analysis of older adult population trends in Perth,Australia

In an increasingly urbanised and ageing world the spatial distribution of an older population is a matter of growing scholarly and policy interest. Much of the research on this topic has tended to draw on one of two key measures: structural ageing, or the ratio of older cohorts to the rest of the population, or numeric ageing, which simply counts the number of older people without reference to the rest of the population. This paper argues that, on their own, these measures have limitations, and that considerable value lies in assessing the interplay between numeric and structural ageing measures. The population ageing matrix, a theoretical framework that classifies the demographic dynamics of population ageing across metropolitan areas, is presented and examined through the case study of Perth, Western Australia. The value of the matrix to reveal patterns and trends missed by analyses of single measures is investigated and areas that are experiencing changes in the composition and size of the ageing demographic are identified. The paper also reflects on the implications of these findings for policy and planning.     

Living the good life? The rise of urban mixed-use enclaves in Metro Manila

Gated communities and other forms of privatized enclaves have become features of many cities. The rise of urban mixed-use enclaves, which integrate functions of work, entertainment and living, is a relatively new and understudied phenomenon that is expanding rapidly throughout the Global South. In this article, we advance the concept of enclave urbanism through a case study of Eastwood City in Metro Manila, the Philippines. We trace the enabling factors for mixed-use enclave creation and assess how the different functions are marketed and integrated in practice into one “live–work–play” development. Based on extensive qualitative research, we argue that the global capital accumulation strategy of real estate developers leads to a strong focus on production and entertainment functions, but neglects questions of liveability. We reflect on the implications of our findings for mega-urban regions and urban studies research.     

基于供给侧结构性改革的空心村综合整治研究

供给侧结构性改革是新时期推动中国经济持续增长的重要顶层设计,其实施将惠及农村的转型发展进程。空心村综合整治以优化重构乡村空间、促进城乡要素流动为目标,通过村庄整治盘活农村闲置土地及其他资源。本文以空心村综合整治为研究对象,探究了供给侧结构性改革对于空心村整治工作推进的现实意义。结果表明,传统单纯依托需求管理的经济增长方式很大程度上导致了空心村问题的出现和加剧。供给侧结构性改革将从补短板、去库存、增加制度供给三方面服务于空心村综合整治工作。为确保空心村综合整治关键技术推广应用,构建了空心村综合整治的制度保障体系,具体包括农村转移人口落户制度、宅基地有偿退出转让制度、空心村整治财税制度以及就业安置和福利制度。最后,基于城镇化背景下农村“人地宅”关系的演进历程梳理,探讨了供给侧结构性改革对于农村新型“人地宅”关系构建的重要意义。     

梯度城镇化的村庄解析：以福建上杭为例

引导农村人口有序地向城镇转移,实现大中小城市和小城镇协调发展,是当前中国经济社会面临的重大问题。归纳总结了农村人口迁徙目的地的4个层次,提出了梯度城镇化的概念,并以福建省上杭县村庄问卷为基础,进行梯度城镇化的村庄解析,辨识不同梯度人口迁徙的影响因素。研究发现：① 村庄人口规模对村庄人口流出具有阻止作用;县城和乡镇吸引农村人口迁入存在明显距离衰减。② 老年人比重高降低了年轻人迁徙到县城的成本,有利于农村人口的县城集聚。较高的少儿抚养比可能会抑制农村人口进入县城居住和拥有住房。③ 教育驱动是县城城镇化的重要动力。高人力资本有流向地级市的趋势。     

Catching sea cucumber fever in coastal communities: Conceptualizing the impacts of shocks versus trends on social-ecological systems

Research on vulnerability and adaptation in social-ecological systems (SES) has largely centered on climate change and associated biophysical stressors. Key implications of this are twofold. First, there has been limited engagement with the impacts of social drivers of change on communities and linked SES. Second, the focus on climate effects often assumes slower drivers of change and fails to differentiate the implications of change occurring at different timescales. This has resulted in a body of SES scholarship that is under-theorized in terms of how communities experience and respond to fast versus slow change. Yet, social and economic processes at global scales increasingly emerge as ‘shocks’ for local systems, driving rapid and often surprising forms of change distinct from and yet interacting with the impacts of slow, ongoing ‘trends’. This research seeks to understand the nature and impacts of social shocks as opposed to or in concert with trends through the lens of a qualitative case study of a coastal community in Mexico, where demand from international seafood markets has spurred rapid development of a sea cucumber fishery. Specifically, we examined what different social-ecological changes are being experienced by the community, how the impacts of the sea cucumber fishery are distinct from and interacting with slower ongoing trends and how these processes are affecting system vulnerability, adaptations and adaptive capacity. We begin by proposing a novel framework for conceptualizing impacts on social systems, as comprised of structures, functions, and feedbacks. Our results illustrate how the rapid-onset of this fishery has driven dramatic changes in the community. New challenges such as the ‘gold-rush-style’ arrival of new actors, money, and livelihoods, the rapid over-exploitation of fish stocks, and increases in poaching and armed violence have emerged, exacerbating pressures from ongoing trends in immigration, overfishing and tourism development. We argue that there is a need to better understand and differentiate the social and ecological implications of shocks, which present novel challenges for the vulnerability and adaptive capacity of communities and the sustainability of marine ecosystems.     

Changing neighbourhood cohesion under the impact of urban redevelopment: a case study of Guangzhou,China

Large-scale urban redevelopment has caused the breakdown of traditional social bonds in Chinese cities. To date, very few studies have attempted to delve into the impact of this urban redevelopment on neighbourhood cohesion. Using data collected from questionnaires conducted in 20 urban villages and 1 urban village redevelopment neighbourhood in Guangzhou, this paper examines the impact of urban village redevelopment on the restructuring of neighbourhood attachment, neighbourly interaction, and community participation—three dimensions of neighbourhood cohesion. Results of a path analysis show that, overall, neighbourhood cohesion declines after redevelopment occurs, and that the sources of neighbourhood cohesion differ between urban villages and the redevelopment neighbourhood. Our findings show that after redevelopment, neighbourhood attachment becomes more influenced by residential satisfaction but less by neighbourly contacts, and community participation becomes less subject to neighbourly interaction and neighbourhood attachment. Such changes occur as a result of the differentiation between social groups and the concurrence of environmental restructuring and demographic reconstruction during the process of urban village redevelopment.     

Zooplanktonic Communities of the Divergence Zone in the Northwestern Alboran Sea

Abstract. Using principal component analysis, the zooplanktonic communities of the divergence zone in the northwestern sector of the Alboran Sea were studied. The study was based on 35 vertical trawls in the 200 metres superficial level. The two first components account for 65 % of the total variance. The first component is a contrast between a warm water coastal community (characterized by low specific diversity and the abundance of Cladocera and Copepoda such as Acartia clausi, Centropages chierchiae and Temora stylifera) and a community of cold subsuperficial water distinguished by high specific diversity and a low number of individuals, one of its most characteristic elements being the eggs and larval stages of the Conostomasidae Maurolicus muelleri. The second component appears to be associated with an ecotone between the communities previously cited, and with a specific grouping (Rhincalanus nasutus, Eucalanus monachiis, Pseudocalanus elongatus, Temora longicornis , etc.) resulting from the peripheral displacement of subsuperficial elements brought to the surface by the cyclonic circulation of water masses between the Atlantic current and the Spanish coast.
